Can we just take a minute to appreciate Matts engineering skills, the man built the Morrvair and this wrecker from ideas in his head and brought them to real life, and they aren't show trucks built to look pretty they are purpose built machines ready to put in a lifetime of hard work.
Bingo, frog snacks!! bingo my friend!! you absolutely nailed it buddy.!!!!
@Erik Larson The WLORW is unique, impressive, complex, and cool looking.
If it performs as Matt thought out in his head, this one of a kind master piece will be well worth the year until it's birth into the off-road world.
@Jona Hollstein Pretty Cool
@Lee D yessir. We call it yankee ingenuity.
Very beautiful said.exactly
I love how Tom actually knows what he's doing and disapproves of many things/processes Matt does, and is almost equally happy and dissapointed when it seems to work out ok anyway.
For total measuring we use mm so you could measure 54.35mm using a digital caliper / micrometer. And if you ever get into precision engineering, we measure microns 0.001 of a millimetre with a digital micrometer etc.... Hope that gives some insight into the metric system, love the video's! Cant wait to see the wrecker up and running!
its mm until that level of precision becomes unnessicary, so 50cm is 50cm but 500mm is that but more precise :)
Hi Matt, love your videos. It is great to watch you guys recovering in the snow while I am sitting here in our comfortable summer weather!
Metric measurements: I often feel agony for you when you have to work in imperial measurements, that we drive me insane! In Australia, we only use metric, so here are some examples as to how we work. Up to 1m, we would only express the length in millimeters, so in your case, yes, it would be 54mm. We would say "54 mils". (I'm expressing that phonetically, if we were writing it down, it would obviously be 54mm) Once we go over 1m, say 3.540, some people will express that as "three point five four zero", some would say "thirty five hundred and forty". We never worry about breaking down 1mm, for 99% of us, that's small enough! I'm not certain, but I think someone working in engineering, say on a lathe, may still work in thousands of an inch. I could be wrong there, maybe they deal in thousands of a mm now?? When you are working on the mighty wrecker, if you got down to tolerances of 1mm, you would probably be okay! Can't wait to see the new wrecker at work! Bless you all 🙂
@Tiln Commonly expressed as microns ;-)
If you need smaller than millimeters, you'd use micrometers, which are 1/1000, but fancier(and shorter) name
Some manufacturing practices confuse the issue. The thickness of some plastics or films may be expressed such as 6 mil poly but refers to thousandths of an inch. Boeing uses rulers that are graduated in tenths of an inch. Some lumber assembly may state 10.5 feet which is actually 10 feet 6 inches. Throw in a British pint vs a US pint and you can start to see why metric is used as a international unit. When the robots of the future overthrow us they can sort it all out. No worries!
Dude! Matt please throw this rig on a scale when you are 100% complete. So interested to see final weight.
You are all so awesome, love the vids everyone
Ed looks great, he is always interested in what is happening and he is always included
Chad needs an award at the Off-road Tow Truck Olympics because he seems to have wired everyone's truck.
@HighTide • 🌑 While Archie’s Edith was an amazing fictional character, Edith Head was the real deal. Hundreds of features across dozens of production companies and studios. A virtuoso of her world. Like Chad.
@David Morris
What does that mean? Edith is Archie Bunker's wife from All in the Family 70s sitcom show
He is the Edith Head of the off-road world.
I like Chad, easygoing and hard-working at the same time
Truth
Love all the guesstimation in engineering here and how well it worked! I've always been amused at people using different colors of Loctite for different things. I've always exclusively used red for everything, even if I plan to have it off within a year. Never had an issue breaking it loose.
I always appreciate that when you change something on the WLORW, or anything else you are working on, you take the time to tell us why and let us watch. The fact that you are always trying to improve on your own designs is a true mark of a craftsman. Well done to your entire crew! As always, God bless and be safe.
Improving on the design is always a plus no doubt. Sometimes its easier to see when its in front of you rather than in your head or on a blueprint.
I will say though it can cause havok as well. You can get caught in a viscous circle. A couple of my builds started with ideas that later have to be scraped due to changes or ideas that came up as I was fabricating.
Built my YJ up most of the way with 1/2 ton axles. Then seriously modified the suspension to the point that the required tire size was going to be too big for a half ton axle. Even with chromoly shafts and stronger joints.
Also after I got the suspension dialed in I decided do a homemade hi-line or high fender setup on my YJ which raised my fenders 3.5". So then I had to go back to my suspension design and lower the jeep while keeping the flexy suspension I fabbed up. I took 2" off the height by reworking axle spring pads and raising/frenching the spring eye mounts. Lowering 2.5" took 10x more work and thought then any kind of lifting ever did.
Lol, sorry. Im a sharer...
Switching to decaf now.....
I've been using Valvoline Wheel bearing grease for 50+ years. Another good grease is Boat outdrive blue spline grease. A little expensive but more water resistant in case seals fail. Hope the new hubs last a long time! Wrecker
is looking outstanding! Can't wait to see her moving under her own power! Thanks for the video!
Hi Matt, yes in Canada we still use the imperial system for some measurements. We do not use deci or deca meters in normal environments. Using millimeters versus centimeters really depends on the accuracy of the measurements you are about to make. We do use have portions (i.e. 2.5cm) but rarely other fractions, we would normally go to the smaller units (25mm or 250 micrometers). Hope this helps
25 millimeters is actually 25000 micrometers. And yes, i know in Canada we're supposed to spell it "millimetres" but it always looks "wrong" to me. Yet micrometer is correct, and micrometre is incorrect. 😂
To answer you question Matt, you would use (up to) w decimal places when you're measuring for applications like building WLORW. As a precision grinding specialist (hey, i don't make up my job title, LOL!) i use 3 decimal places - which takes you into the realm of microns. To put that into the physical world that most people understand, the human hair is 0.003" in Ø. That equates to 0.0762mm. Hope that helps you better understand the crazy metric world.
Seeing this wrecker in action will be awesome! The work that has been done is amazing! Matt and crew, good job!
We all need someone like Tom Tom in our lives making sure we stop delaying fixing broken things and do it the right way.
Tom is slow and steady, and Matt is pedal to the metal. They compliment each other very well!
Is that called a wife??
@MediocreMan same
I already am that guy. I need someone that helps me just do things and not worry about perfection lol
People would bring their car in to my dad after getting tires put on at another shop. The other shop tightened so tight, they wouldn't come off. My dad would send them back to that shop and they would sometimes break them off. They never learned!
What a great idea! Audible low fuel warning for Matt’s rigs! Enjoyed
I have come to admire Tom so much more since he came on to the channel. I didn't know who he was at first because I've only been watching for a couple of years. He has depths of knowledge. MorrTom!
"Kind of like pliers. We did a little bit of everything, but nothing really well." Words to live by!
Love watching you guys!! Awesome build so far!
To answer the metric question, we (in England) use the metric decimal system so we don't use fractions. We use the decimal equivalent. Everything thing is based on the millimeter (mm)
1 inch = 25.4mm
1 1/16 = 26.9875mm (round up and say 27mm)
With very accurate measurements, it's still based on the millimeter
1 micron = 0.001mm
If you're measuring something big, you would move the decimal point.
2.5 meters = 2500mm you would just say 2 and a half meters .
I absolutely love how quickly Matt moves from 0 to 60 when sparks start raining down from heaven. He went from Zero to 60 in 0.03 seconds, and then immediately back to Zero once he found the source of the problem. "We're gonna need a new one of these". Hilarious!
The absolute best person to have on your team is someone who cares enough to respectfully question your methods. I know it can cause friction, but if you can get that relationship to work out, it’s frickin’ gold. I think you guys are working together brilliantly. Tom Tom is awesome
It seems Tom Tom has learned to do the right thing the right way. Now he is learning to do the right thing the wrongish was lol.
@Dave Runion Yes.
Guys like tom tom are many times the difference between the people being recovered and the people doing the recovery. Every team needs this person, a voice of reason, to be successful… but not more than 1 or nothing gets done. 😂
I agree. Having only yes-men around can lead to disaster. Trust but verify.
The boss who surrounds himself with yes people is setting himself up to lose.
I would like to point out that in your shop you have a bridgeport that can do precise cutting which would be a good option if you lack a lathe, but, i guess an angle grinder works :)
I absolutely love the world's largest wrecker videos! Great job , man I can not WAIT to see this thing in the rocks and sand
Another great video from the whole crew in Hurricane! Looking forward to the Wrecker competition, it appears Matt has it in the bag for that #1 trophy!
I have always admired how you handle inch breaks. Here in Germany, in metal construction we allways measure in milimeters. Smaller than that, we talk about tenths, hundredths or thousandths of a millimeter. For example, if a shaft requires 1160.54 mm nominal dimension, this would be one thousand one hundred and sixty comma fifty-four mm or eleven hundred and sixty comma fifty-four. We use a comma as decimal separator.
Im an engineer who uses metric at times.
I usually use just mm & meter, with using decimals on the mm even though there are finer measurements.
If its something ultrafine you step down another 1000 to micrometers. The fact that there is a unit every 10 is nice but usually moving in 10^3 suits me best for units of length
@Evan Walters 23mm is still way too large to use microns. I'm an engineer in the US and we use microns when talking about things that are less than ~0.1mm.
I challenge Matt to use mm for a week.
In Australia the engineering I've been around stay using mm's no matter how small, we don't go to microns. If it need that much precision we would say 23.589mm instead of 23589 microns.
Our measurements are usually given in one unit because they are always multiples of 10, so you can easily divide them in your head. For example, you might say 1050.5 mm, which would otherwise be 1m, 5cm and half a millimetre. In Germany at least, tyres are measured in metric, only rims are measured in inches. P.s. Love your videos, Matt and crew
I guess that even in Germany you are using km (1 km= 1000 m = 1000000 mm) for long distances?
@Peter O'Halloran Haha, “most” as in the ones who make a living reading measurements. As far as the general population, they can’t read the imperial ruler, much less the metric system.
@Savage63 Same for me the other way around! And it's mostly fine - just a different base unit. But the problem for us metric types is the constant use of fractions when adding and subtracting measurements. It breaks my head! But only because I never learned or practiced it. To your point.
@KJ That's absolutely fair. Interesting that you say "most" though. Clip-Share will have me believe that everyone in the US is completely and utterly confused with metric 😀
Only dressmakers use centimeters. Any professional or engineering type will only use millimeters and microns.
I love how Tom just goes along with it when he knows it isn't right, but it always works out. I love it. great one two combo on the channel. Tom Tom getting funnier. Pink Grease - Timken.
I think they are both learning from each other in this team. Matt is rough and ready but knows if something fails it will be out on a track somewhere with only basic tools. Tom is a workshop engineer who knows how to do the work properly but not always practically. They are both giving a little more to the other each project.
Yay! Great progress guys, thanks for taking us along! I love your work :D
You've probably had several thousand answers to your metric question but I'll add my 2 cents worth. In the construction industry here in Oz we use strictly mm, i.e. a house will be 8450x14960mm overall (and we would read that as, 'eighty four fifty by fourteen nine sixty,' because we're lazy and saying, 'hundred,' let alone, 'thousand,' is way too much effort and by only using millimetres we don't have to specify, again, saving words!).
In furniture making we'll work to a tolerance of 0.2mm, 'point two of a mil,' (gotta say it with an Australian accent!).
Verbally we may say, 'we're out by half a mil,' but otherwise don't generally use fractions and certainly not in written form.
Tyres (tires) yes, are weird... our rims are measured in inches and tyres come in either imperial (like a 31x10.5R15) or metric though metric sizes are retarded. A metric tyre might be a 265/65R17 which is 265mm wide with a side wall 65% of the tread width and a 17 inch rim (which amounts to basically a 31" tire!). Whoever invented that system was a creative individual but at least we can still run American made tires on our vehicles...
Anyway, back to the wrecker!
Oh yeah, love your channel and the family you surrounded yourself with!
Looking like a fun build Matt and crew, on the grease question, I personally use mystik, or royal purple, with working in the oilfield, as well as farming at home these 2 greases put up with alot and are very good.
For heavy duty automotive and equipment lubricant grease hands down the best I have ever used in my 40 years as a mechanic is Chevron Ultra Duty Grease EP (extreme pressure). Very good for packing wheel bearings. Plus it’s red for Tom Tom!
Hi, Jo from Germany here. I love your show! As far as measurements are concerned, in situations like this we use only millimeters, for example we say "you need to cut off 38 mm". 1 mm equals 0.039 inches which is already quite small, but it's quite frequent to divide the mm in its decimals ("1.2 mm").
I used to be a science teacher in the mid 1970s and I would teach the kids about the metric system and demanded they use it. There was the usual whining, but I gave them 2 quizzes. The first one was a quiz on the English system, it drove them crazy. For example: How many feet in a mile? How many inches in a yard? How many ounces in a cup. How many ounces in a pound. How many pints in a quart? How many quarts in a gallon? You get the idea, they didn’t know most of the answers. Then I gave them a quiz on the metric system. I constructed the quiz so that every answer was 10. For example: How many millimeters in a centimeter (10). How many centimeters in a decimeter (10). How many decimeters in a meter? (10). How many decimeter is in a Kilometer (10) How many grams in a centigram? (10) How many centigrams in a gram?(10) How many grams in a a decigram (10). How many decigrams are in a kilogram?(10) if you know these, how many milligrams in a kilogram? (1000- 10 x 10 x 10) same goes for all the rest. It was then the kids realized the metric system is just a series of multiplying or divided by 10 it’s easy! Then I showed them the easy method of just moving the decimal point. For example How many centimeters in 205 millimeters. 205/10 is 20.5 centimeters. See it’s easy! I showed them the DRUL rule. From biggest (Kilometer to millimeter) from top to bottom, largest to smallest. The DRUL shows that as you go down you move the decimal to the right (Down Right), if you move up, How many millimeters in a Kilometer you move the decimal to the left (Up Left). Eventually I convinced most of the students that the decimal system makes much better logic. Everybody can multiply and divide by 10. Hopefully! Hey Matt and Tom, you too can be comfortable with the metric system. It will require you to buy metric wrenches which I bet you already have. You too can master the metric system!
Mac from Canada here, we do the same here as Jo from Germany, the only time I have heard anyone use decimeters was a road builder and he would say stuff like " We need to bring it up 3 decks here and cut it down 2.3 decks over there, so just use that fill from over there to build this up here!" BUT I have never heard any other crew use decimeters that way.
And in fabrication 1mm is almost every time small enough. I mean how often do you need something more precise the e.g. 3 13/16 inches. For machining we of course use 1 or 2 (or even more) decimals.
For bearing grease, the best I’ve found without getting into specialty stuff is Chevron Starplex. I’m up in Canada in fairly harsh conditions for bearings and have found that this sticks around.
Glad to see TomTom fussing Matt’s shortcuts haha. Another great video thanks guys.
Loving the extended videos! Love the 4 wheel steering. Can't wait for recovery's. It's gonna be a cake walk
Not without the key
TrailMater mentioned that March’s event will include a shuttle bus. I immediately thought of Heavy D’s off-road party bus being the shuttle! That would be epic!
I like what your shop does. Is there the "right" way sure, but know that you succeed with your methods, gives me the confidence to tackle some of my own shop projects. keep it going.
22:14 metric would all be said in mm mate. use cm for big stuff like doorways, and use mm for small precise stuff like the steering stops. So what you are making would be 54mm as you said. G'day from Tasmania, Australia long time subscriber of your channel and love all that you guys do.
@michael howell Just measuring by the inch is the most common way in the U.S. For example, in construction, the standard distance between studs is 16 in. You'd say it that way instead of 1 ft 4 in.
Correct, and if you just want to move for 54mm to cm. Then it's just 5.4cm.
@michael howell half of a mm is 0.5μm ...
This comment should be at the top. This is all i wanted to know after he asked this question as I didnt know either :D:D
@matt somerville Learn something new every day. The way I wrote it before is How everyone I know would say it, but we all use metric system and the mm
Just found your channel tonight, an I can't stop watching! I've been building motorcycles and offroad trucks and muscle cars for 20 years, with absolutely "poor guy" tools and for a long time laying in the rocks on the side of the road...lol. I absolutely love you guys. Wish I had the capital to do the things you guys do. Almost done with my 78 GMC monster, I have been rebuilding from the ground up for almost 15 years. Never been on a vacation in my adult life, but would love to come hang out for a while and ride some trails and work on some stuff. Love your attitudes! God bless you all and keep up the good work!
You should start your own channel and show us the work you’re doing
Seriously hoping to drive out for the wrecker event in March. Driving from Indiana I’m concerned about the chances of not getting past potential weather events this time of year. Do you have any feel for what is typically the situation in March coming across I70 ?
actually, with your application and environment, I prefer the green farm implement grease. It resists water way better than even Lucas ( which I do like the red and tacky ). and in general it just seems to stick to parts a lot better.
I still dont know why I watch these videos... pure awesomeness, i dont need an antidote to this.... will always be looking forward to more content...
What a crazy awesome amount of work! Good job !
It's great seeing the progress on the wrecker. And for measurements we wouldn't use fractions or swap units and instead just use additional decimal places depending on what suits the scale of the part.
So its not 13cm and 2.5mm, or 13cm and 1/4, but it could be either 13.25cm, or 132.5mm. It's definitely a lot easier to work with, especially at small scale
@tristanask That's probably, because to someone used to the imperial systems these _feel_ like different units, as it is the case with miles, feet, inches. The latter really are three different units for lengths, that need some odd factors to convert.
But with metric system, km, m, cm, mm actually are _not_ four different units, that happen to have easy conversion factors, but the unit in all four cases is the same: m (meter). The unit prefixes "k…", "c…", and "m…" actually are only factors: k=1000, c=0.01, m=0.001!
It changes completely your perception of metric units, if you understand to bind the prefix to the number.
So 5.3 km actually is 5.3k m - unit meters! As 5.3k = 5.3×1000 = 5300, so actually 5.3 km = 5300 m. So this is no _unit_ conversion, but changing the _number_ by factors base 10 (which conveniently just shifts the decimal point).
You can do that even with an Excel cell format! :) Imagine some engineering, that internally measures everything exactly to the mm, so measurements might be something like 5, 23, 1500, or 3250000. Using this cell format:
[>=1000000] 0.0,, "km";[>=1000]0.0, "m";0 "mm"
the display of these numbers will be 5 mm, 23 mm, 1.5 m, 3.3 km,
but you still can calculate with these cells and do sums and whatever, because the stored numbers are not changed.
Only dressmakers use centimeters. Any professional or engineering type will only use millimeters and microns.
@AJNpa80 Yupper, that's what most of us do in Montana and Wyoming, too! I've been 'mayzuring one thing or another, for almost 69 years now. I'm to old to learn a new language!
@vipecrx I think what John Russell means is that most engineering measurements are done in mm not cm. So using metric but just not cm.I studied Architectural Engineering ( not what I do for a living now) and we worked in mm or m, very very rarely cm.
@AJNpa80 then drive through the crick, and up into the mou'uns.
Hey Matt. I work in printing and we use millimeters for measuring all the time. I have never heard centimeter and decimeter mentioned since high school. Also personally I have never had an occasion where the tolerance was tight enough to go into fractions of a millimeter.
I've been watching your videos for about 2 weeks on Facebook. When I ran out of content I looked up your Clip-Share channel. I love the dogs, but sometimes I worry they get too close during rescues.
Tom cutting that axle was definitely a “disagree and commit” moment. 🤣
Have you looked into a pressure relief by pass for the hydro steering?
This would reduce the possibility for a failure due to over pressure
Love the channel
Tomtom, you have been my hero in so many ways. Where are your safety glasses when you are drilling and grinding on the rock slides??
You could do either 52mm, or 5.2cm. In my workshop it’s usually called out in millimetres unless stated otherwise, e.g. “cut this down to 52”. For smaller measurements you use decimals on the millimeters, or go to a smaller unit.
@Edmo130 yeah but they used metric to put them there
You don't know that NASA use metric, I understand.
They use metric, because they are smart enough to understand that metric are superior 😉
@Edmo130 nope theres only the 1 one kind. The "other" pretends it uses the imperial system. Basing imperial measurement on the metric system standards. Silly Americans, its just like using the metric system just with extra steps :)
Everything should be in millimeters
Everything
Even large measurements, 5m is easy in mm, just 5000 mil.
@Edmo130 By law, the official measurement system of the United States since 1975 is the metric system.
The Metric Conversion Act of 1975 (later amended by the Omnibus Trade and Competitiveness Act of 1988, the Savings in Construction Act of 1996, and the Department of Energy High-End Computing Revitalization Act of 2004) designated the metric system as the preferred system of weights and measures for US trade and commerce, and directed federal agencies to convert to the metric system, to the extent feasible, including the use of metric in construction of federal facilities.
For the metric system, usually when it's above 10mm we start calling centimeters. However in some cases like these kind of measurements we would say for example 54mm. Or 5.4 centimeters. If you need to be more precise than that, you can divide the millimeters. 54.5mm is fine (between 54 and 55 mm)
I shed a tear every time they have to take a cutting wheel to something they’ve so masterfully created.
@David Acton Man, you absolutely nailed that one!
I shed an anticipatory tear every time I see them using an angle grinder with NO SHIELD on it!
@dhrracer Good point!
If they so masterfully created it they would not have to take a cutting wheel to it.
It doesn’t matter the colour of the grease to me, packing hubs is something I just do and enjoyment doesn’t enter the equation. It might come from growing up on a farm and my dad teaching me using the open pail of grease and having to scoop it out by hand. Then to go back into the house mom would want every speck off. Probably was a way to keep me busy.
Sure glad that you take the time to do these videos.
great build guys!! Those rear shock reservoirs would look great on the 2 cross braces, if thats not what you've already decided to do
@Butch Greene im guessing for the majority of applications they will work, which Matt probably did. im pretty sure you would be able to buy them in either configuration
I'm confused as to why the reservoirs are mounted to the shocks. I'd much rather have them remote on a braided steel cable
Due to the metric system being divided into tenths, you would usually choose the unit that best represents the objects length, for example i would say that bolt is 23 millimeters long (ca. 1 inch), a saw blade is a 15 centimeters (ca.6 inches) in diameter, while a bridge is 45 meters long (ca.147 feet). A rule of thumb that I use is that if a length has more than three numbers, like 3654 mm, and is not in meters I change the unit, so in the previous example it would be 365.4 cm. But you should always choose the unit that makes the most sense in your application.
If you need measurements smaller than millimeters you do it with decimals, ex. 0.1875 mm, rather than 3/16 mm. If the measurement is 2.5 mm I would say "2 and a half", but "2 point 5" works just as well and is perceived as a bit more exact in some cases.
@Niall Stoddard the milli prefix does mean thousandth(10^-3). So either they stole the prefix from that definition or it was called a milliinch then shortened to Mil. Looks like I have some history homework.
@Lachlan Goll Want to get more frustrated with the Imperial System?? a 'mil' is a Imperial unit referring to 1/1000th of an inch. Depends on the field, but a lot of people call it a 'thou' or 'thousandth' instead which makes it often less of a concerning overlap.
@Lachlan Goll I usually doesn't say what unit I use, unless it is in a range it can be confused with another unit.
Tldr: metric > imperial
Yes, to be picky, we never change the unit. We only use different prefixes, its all based around the metre.
The imperial has different units that represents different lengths.
✨🙏🌊💙🌎💙🌊🙏✨...out of curiosity...was turning the big one in to a six wheel drive a consideration? Pros and cons to this question please,love watching you all, thanks....
"I think we need an audible siren..."
"People say you need that for your fuel gauge!" Hahaha; amen to that!
Also, very cool to see that swapping the shocks around gave the clearance needed.
In metric, you only use one set of units. Which units you use depends on how precise you want to be. It is rare to go past one decimal, so 6” is 152.4mm (or usually, 152mm). If you want more precision, you use micrometers or even nanometers.
TomTom is such a good man, coworker and friend!
Would ya do an updated video on your recovery gear. Would be cool to see the difference between the two videos.
Nothing says Sunday morning like watching Matt work on his truck...
Here in South Africa I watch him on Sunday afternoon
Exactly!
Wish Matt would do a mid week video on the wrecker too
me drinking my coffee enjoying matt on sunday morning 😂
Facts
Love your videos. I have the greatest respect for Matt and his knowledge and heart.
My favorite grease is the Redline CV-2 :) worth checking it out especially for heavy duty stuff. All we use in our race cars
Can't wait to see it on the road, it's going to be a beast!!!!
You use all millimeters and the decimals after are microns. It works a lot like thousandths. So, for example, 1/2" is 12.7mm which would read 12mm and 700 microns. I hope that helps!
Soo as a european whos always super confused with your imperial system i'd say that when doing metalwork you usually use millimeters with decimals if presicion is necessary.
Carpenters and woodworkers mostly use centimeters where I'm from.
Greetings from Austria and keep up the good work!
For the metric system, generally up in the great white north, we either use MM for small measurements, and normally CM with a decimal for larger measurements. So something that's 325mm, would be 32.5cm. Great work guys, the wrecker is really shaping up. It's was always fun doing shop work with my dad, because he's an old school machinist, and everything for him has always been imperial measurements, but everything for me in school was metric. So it took a while for me for me to get used to imperial, but for some reason a lot of the trades still use it for everything, construction is one, you never see guys using metric for that up here. Honestly, its kind of annoying.
@Shane Booth Then also, there are three different measurements for tire width. You have to know which manufacturer is using which measurement. They are either measured across the tread, across the widest part of the sidewalls or the width at the rim. They all make a difference to the actual tread width.
Only dressmakers use centimeters. Any professional or engineering type will only use millimeters and microns.
Can i suggest a vid called "Matt & Tom's Metric Madness" where everyone in the workshop has a laugh trying to stay in metrics?
Matt as a metricated Kiwi, if I was in your workshop helping on the Heavy Wrecker I would just stay in mm for everything engineering. I'd use tenths of a mm for accuracy I.e. 12.7mm is verbally expressed as 'twelve point seven millimeters.' The numbers can seem large, but no worse than when you say a vehicle is 17000lbs and my brain has to translate that to roughly 8.5 tonnes to understand you :-) Where you might start to like metrics is adding say 3 lengths together all with fractions to get a total length: 3 3/16 "+ 5 5/8" + 2 7/64"=?? 81mm + 143mm + 53.6mm = 277.6mm I get a lot less brain fade adding decimals in my head or on a scrap of cardboard.
New Zealand went metric when I was at school. So I can do both, tho having spent my adulthood as both a graphic and product designer I think on balance it was a good call. But you be you - you do it so damn well!
@Trif 55. Tyre sizes like that is the biggest head crunch going, 3 different measurement methods…
I've seen machine shop measurements well over 1meter called out as like 1340mm it's just always mm,
our tyres are great, e.g. my toyota takes: 205/55R16
205 is tread width in mm
55 is 55% of the sidewall height as a percentage of the tread width
R16 is the wheel rim in Inches?! lol
my dad was old enough that inches were common at home and all our rulers still have both on, doing rough wood work as a kid I just used inches plus "a bit" where required, these days I use cm for estimation and mm for real work but am in the boat of not understanding imperial fractions at all
Tom is an excellent addition! Love em'
I love watching the way you guys build and figure things out, i have no comments on that other than please continue with the creativity. With that said, 2.25" would be 57.15millimeters and its pronounced MEH-surement not MAY-surement. Cheers from Canada..
The best wheel bearing grease is the one that's in the bearing. It really don't matter that much, just make sure it's packed properly.
Tom Tom,use safety goggles when working with the grinder. The sharps can really damage your eyes permanently.
Grease recommendation: Lucas Mining and Construction Grease. It's got a decent amount of moly in it, and it has some absolutely killer performance numbers (if they're accurate). It is rated as a GC-LB product, so it's rated for use in wheel bearings and chassis grease points.
Tom is quickly becoming one of my favorite MorrCrew members. I love that man’s knowledge and ideas he brings to the crew.
@Thomas Siegfried well obviously? I just don’t see the reason for the engineer comment. If I had stated the same thing about Ed for example, then someone chimed in with “he’s a gold miner” as if it made the previous statement any more or less true. Having an engineer title doesn’t mean you have the knowledge to do anything in it’s respected use case. Just means you have a degree or use the title engineer. My comment was reflecting that Toms prior knowledge of vehicle work and adaptive abilities has made him a great addition to the team. Just like everyone else on the crew.
Tom is not making hack jobs as all other americans, including matt
Engineers job is to do that?
@zoltan liszkai yeah. And?
He is an engineer.
the fun thing with metric is that you can just easily convert to finer units if you need to. so you can make out of 3.5 meters (to 10cm accurate) 356 centimeters (to 1 cm accurate) or even 3562 millimeters (to one mm e.g. 1/10th cm accurate) to get more precise measurements. most of the time millimeters are fine enough for general fabrication
Having grown up with the metric system, for shorter lengths I would definitely use just millimeters - as in 53 mm. (I don't think I've ever heard anyone say, "5 cm and 3 mm"). Even larger measurements are often expressed in millimeters, such as 1435 mm for standard railway gauge.
Shock socks (normally for motorcycles) would work well on your steering setup so you don't jam mud and debris into the seals
For centimetres we usually use decimals instead of fractions. As exemple à 10 cm & 2 mm part would be a 10.2 cm part. You have the choice to do all mm as well, but might as well enjoy the fact that 10 mm is 1 cm, 100 cm is 1 m etc. On the contrary you can't say 10.2 inches from a tapes mesure. It would be the closest fraction
Hi Matt, in Germany, engineers and hobbyists usually use millimeters [mm]. They usually omit the indication that it is in millimeters. So if the bolt is to be 0.25 meters [m] = 25 centimeters [cm] long, they say 250. But you hear other specifications, too, mainly in stores like Home Depot.
When you measure something with a caliper, you usually put a period after the decimal point. If you should make a component "a little" smaller on the lathe, then many also say that you should take away 2/10. What means as much as 0.2 mm. Fractions, however, are only used as multiples of 1/10 or 1/1000.
It is similar with the threads. No one would specify the pitch for the standard thread. A metric thread is not M8x1.25 - it is M8, unless you have something different. Then the pitch is explicitly mentioned. So for an M8, I would pre-drill 6.8 and then tighten the bolt with a 13 wrench. Whereas a 17 wrench can be a wrench and a synonym for a beer bottle opener ;-)
Speaking of threads. Here, with car tires, pipes, ammunition, powder charges, imperial units appear again and again. Likewise, certain, mostly older professional groups also have special units that not everyone knows. As an electrical engineer, I find it confusing that in Australia millimeters are often referred to as mils, whereas for electronic components, even in Germany, the unit mil = though = 1/1000 inch is often used.
Best regards and thanks for the great videos. I am looking forward to the Wrecker Games like a hawk.
In cars, the Japanese have often an mm smaller bolthead so 13 is 12 and the treads are tighter so M 12 is often 1,50 mm instead of 1,75- not fun to try the wrong threads...
Of all that, I got that a 17 mm wrench is a beer opener.
Measurements on my offroad jeep are done in quarter inches and an angle finder. Especially when it just gonna bomb through the forest and parts will be replaced or changed the same month, why bother making stuff perfect.
Always go mm unless you need less accuracy than a cm. So your wheelbase might be 3850mm. Concidering a mm is way less than 1/16", they usually don't need to be split unless talking clearances, then you usually use a decimal and 10ths, 100ths and 1000ths. Been working on Japanese bikes for decades...
@sgt_mcnuggets No, because that is not the same number.
@sgt_mcnuggets Every dimension is rounded to the maximum precision of the instrument used to measure it or the practical limits of the design intent. Nobody in the trade would see 3854mm and 3.85mm as the same dimension, but 3.854m would be seen as the same
@Dwayne Penner Mate I am a machinist. The only time how many zeroes you use matters is on a ASME drawing if the title block specifies implied tolerances. ISO or anything else resolution doesn't matter because tolerance is not implied. If you're giving someone a generic measurement the amount of zeroes you add is irrelevant. Someone giving me a 1.23" vs 1.2300000000" measurement doesn't matter to me without a tolerance on it. If you do this to a machinist they will think you are a fresh graduate or sharp as a box of rocks.
@SuperAWaC i mean it does though, if i say 3854mm you could still way its 3.85m.....
@SuperAWaC Tolerance is not implied, but I wasn't talking about tolerance I was talking about resolution. In fact I never mentioned or even referred to tolerance. But for your education tolerance is the acceptable deviation from the nominal (or in the case of measurement the actual). Tolerances are usually expressed as a +/- value and are NOT included in the measurement itself; they are usually communicated in the standard/specification/contract/drawing etc. Resolution is the how sensitive the instrument and /or the measurement is (what is the smallest value that can be determined). Try passing off a 1.230" measurement at a machine shop as 1.23" when accuracy to the thousandth (or even half thou.) is expected, and see how it goes when you explain they are exactly the same thing. Zeros to the right are significant and deleting them because you think they are extraneous is NOT how it works in any industry I have been in, which includes construction, aviation, oil and gas; try that and the part you order has a 9 in 10 chance of not being the right size. A zero to the right means that you need accuracy to that level, and removing a zero reduces the accuracy, in the example if you state the part needs to be 1.23" you are communicating that a part that measures 1.234" would work just as well as a part that measures 1.230". If you want your part to be accurate to the thou. you communicate that with the last zero.
Greetings from Germany, love your vids! Always makes me wanna rebuild my feroza.
For the metric system, you can say like 9,5 cm or 95 mm, or even 0,095 m if you want to.
All dimms are expressed in mm here in the UK (except for plumbing, they strangely use all sorts of different systems!), so something that is 12 metres long would be 12000mm. All drawings I've ever used have "all dimensions in mm" stamped on them, saves a lot of confusion.
I have one more comment I think Matt's off road, fab rats & Robbie Layton should have your own reality tv show bc we love all 3 families & we love seeing them all together we also wish they would introduce their families bc sometimes it gets a little confusing on who's that is lol but my family loves u guys & we love watching y'all!!!! Much love from Greenup co Ky aka flatwoods ky! ♡♡♡♡
Matt seems to solve issues by trial and error, most engineering process's evolve like this. Remember too many cooks spoil the broth!
Love that Matt can use the impact and know when to stop and be within reason of the proper torque.
One thing I will mention on torqueing wheels, when over torqued the risk isn't just marring the threads, you can actually stretch the studs which weakens them and you add the risk of them breaking. I own my own semi truck, over-torqueing lug studs can end in sheared studs and wheels running away.
Keep up the good work guys, love watching all the shenanigans you get into!
On cars, the torque is especially important on light alloy rims - if they are tightened too tightly, microcracks form on them and you can lose the wheel, especially when the load becomes high such as when cornering and turning at higher speeds where you absolutely do not want to lose either steering or braking ability!
Sheet metal rims have a much greater tolerance and there it is very true that the threads give way or that the bolt comes off due to fatigue.
Tom Tom is a really good addition to your team and at least should get the award for employee of the week award for helping on everything hes asked to . Smiles 😃 from Canada 🇨🇦
and i think he's the voice of reason.
when you get the wrecker all done, i was wondering how do you get it to a job sight with the people you need for recovery and camera work?
For those who are complaining about the lack of security glasses, Matt is using two @31:41 :)
Made me go back and look!
Tom Tom is such a good add to the team!
30:22, Tom Tom respectfully: "If we flip the shock around...and just rework the back of this, how much work is that? Is that a ton of work?" Dear Matt: You really couldn't have appreciated this best of all solutions for the shocks more gratefully than to start implementing it together with its creator without hesitation. Sometimes it's damn hard to acknowledge with words that also "the other one" has it simply fully on it. I understand: You brought the whole thing into being. But the more you share it, the more it will fulfill you. It is great to see with you - looking at yourself critically in the mirror - how the successive admission of this realization enriches your life. You are a great team, all together! Do not stop growing in this way.
I grew up in my dad’s garage, then went to school for mechanical design and learned the ‘right’ way to do things. To this day, one of my favorite things is all the ‘wrong’ ways my dad does things, and how well it always seems to work. What I’ve learned from all this is that there’s theory, and there’s practical application. Both are valuable, but at the end of the day, practical application always wins. If it’s stupid but it works, it ain’t stupid.
As for metric system…
3,256.3 millimeters
325.6 centimeters
3.3 meters
Instead of fractions (3-1/2mm), you use decimals (3.5mm). For example, instead of 3-7/8mm, you’d use 3.875mm. Since millimeters are much smaller than inches, I’d likely round it to a single decimal place and maintain accuracy, so 3.9mm. And so on. Just depends on how accurate you need to be for each measurement.
I prefer metric, my dad can’t wrap his mind around it. My argument is basically that it’s easier to add metric numbers than un-like fractions. I can do it, but it involves converting the fractions to like denominators and adding fractions. Using metric just saves that step.
Example:
3-1/4 + 3-7/8 ->
3-2/8 + 3-7/8 ->
6-9/8 ->
7-1/8
Or in metric:
3.250 + 3.875 ->
7.125
However, my dad’s just done fractions his entire life, so it’s automatic for him. He’s a much better mechanic and fabricator than me, so do what works for you, as long as it works.
I’ll also point out that it’s harder to find a metric tape measure, square, etc. They’re out there, just not nearly as common, so there’s that.
Clear as mud? 😂
Danggg
That’s nice and all But a car engineer will walk past 2 Virgins to screw a mechanic.
Well explained
Great explanation 👍
That was impressively thorough. Thank you. i agree on all points
Automotive OEM experience. Millimeters is the standard "inch" measurement. So all numbers are 2 3/16 would be 55.55 mm or gnat's knees would be 55.549 mm which would be an accuracy 2.1875 inches. Far more information than hand drill, bit or grinder will ever need. Really enjoy the build.
Metric v Imperial is a hard one, I live in Australia, so I learnt the metric system but have always used whatever is the easiest for what I'm doing 🤷
PS. I always find the smaller the measurements I use metric way more often, millimetres are my default.
I'm in England, and always use mm for small numbers - up to about 250mm. If I needed accuracy using calipers I would say 54.6mm, or even 54.65mm.
Larger sizes might be cm up to a metre (never decimetres!) although I tend to say 0.76m for 76cm.
Challenge Matt, purchase a tape measure that has both the imperial and metric system on it. It wont take you long to learn how easy it is to measure with the metric system and you may over time start to preference it. When I was an carpenter many years ago you would sometimes use the terms "full or bare" to break down one millimetre. e.g. 55mm full means about half mm longer
Matt - I enjoy your content to the max. Just wish you'd wear eye protection when using a grinder and so forth. Thanks!
Usually I'd never measure any more detail than to a whole millimeter, but if you're machining something precise then most calipers go down to 0.1 or 0.01 millimeters.
But we don't go into fractions like 1/4 or 5/16. It's always decimal based.
Edit: what Tom Tom said is pretty much correct, no decimeters and usually not centimeters if you're blue collar.
I think you might damage the ram seal housing when the steering bumps out. Eventually it will smash the cap will and potentially ruin seal.
For the measurements in metric, you move the decimal to be a suitable unit choice. For example: 2356.2 mm could be left as is, or converted to 235.62 cm or 2.3562 meters. The units you use is up to the person but also should be suitable to the distance. You wouldn't use mm to represent 2.35 kilometers. Also, the number of decimal places you keep is dependent on the accuracy you want. 2.35000036 isn't necessary if you are ok with 2.25 or 2.4 as being accurate enough for the application, sometimes you need a high number of decimal places though. As for if you would fraction, no, not typically, just use the decimal place. You wouldn't say 2 1/2 millimeters, just 2.5 mm.
AAAHHHHHHHHHHH I cannot wait to see this beast in action! in so many recent videos i keep thinking, well the wrecker would have just pulled that right out! i can't wait to be right and see this thing slay :)
For using metric, we just use overall millimeters. theyre small enough that you dont really have to break it down further. you can get metric measuring tapes and theyre great. even if something is 2280mm we would still measure it in millimeters like that at work. i dont think ive used the term decimeter since elementary school, but meter, centimeter, and millimeter are common enough. on blueprints for fab its all millimeters though
