In the early 1980s I worked on a Ralt RT4 and we used a very simple lever hooked to an old dial type tension wrench to lift the wheel. We would have a piece of paper under the tyre, when you could just move the paper you would read the scale. It gave surprisingly repeatable results.

[@fredericrike5974]

I used to run around with some dirt trackers. Big believers in wedge effects- I believe "boogering the wedge" is about getting it wrong. Don't quote me on that, but that was what I got from it, listening while I laid under the car draining hot rear end oil out of the quick change so we could change the ratio between heats. The notebook our "crewchief" kept on all those "little arcane details" was always kept locked up when not directly in use. I really like your work around- it could catch on, especially if you could figure a way to put the readouts on a phone app for comparison. I am a plumber and merely have typing skills and a cousin to fix the damn thing when I press the wrong button! FR

[@SuperfastMatt]

That makes more sense that boogering would be getting it wrong. I heard it a few times long ago but don't remember the context so that might be true.

[@fredericrike5974]

@@SuperfastMatt It was a "bizzy minute"- a 15 minute feature while we were in the pit from a 2nd place finish! They wanted a little lower axle so the 25 gal fuel cell of methanol would finish the race. The track had started wet and dried up, "boogering the wedge" all up- the car wasn't handling like it started. Bill dug out his "top secret" notebook and started telling people what to do- they were using the large equivilant of a hanging fishing scale to '"read" the wedge. I guess it worked- Randy won the 25 lap feature going away- the engine was up to black smoke by the last lap so the joy was limited. Those were the days, my friend! I did like your answer to the scales problem- all it lacked was a simo four wheel set up and a screen to read it all on and I thought about all the home automation deals that the cell phone reads and reports. The Jag ought to get you another trip to Leno's- I'm jealous! FR

[@djhedges]

I really appreciate seeing the failure attempt. I went down a similar route looking at load cells and live stock scales before eventually caving and buying a proper set of corner scales. You touched on the garage being not level but you might surprised how unlevel it can be. My garage drops almost 3/4in of my car's wheel base.

I have an even cheaper way in the form of taking a singular price of metal to a scrap yard. And weighing on the way out.

[@fericyde]

Simply awesome -- I have wanted something like this for years (about a decade actually) and here you go bringing something that not only works well as a scale but honestly can do double duty. I tried making a similar lever system to what you did and gave up on accuracy plus my version was outright dangerous. 5-10 bucks at a truck scale is what I ended up doing -- but that involves driving to a truck scale... Highly recommended if your car is say, moving but has its own pitfalls. For one, truck scales are fairly accurate but only in a relative sense. Like relative to the humidity and temperature that day for example. Still, this is better. You can calibrate this easily by simply standing on it. It's portable and has the aforementioned double duty as a useful tool in your shop when you're not weighing stuff. Kudos man, love your channel. Plus your video editing skill ... dude. Thanks for sharing.

[@themistoklisanastasiadis]

the easiest way would be to go where they weigh trucks, front tires on the scale, rear off, then rear on front off. you have your weight ratio. and for sanity check, weigh the whole thing, see if the numbers match. those things are cheap to use, in my area, (Greece) the normal charge is a couple to 5 bucks average.

[@steverabbits]

Just use 2 bathroom scales adjoined and with a piece of wood across them, put a block of wood under each of the 3 remaining wheels that's the same height as the scales+wood and weigh one corner at a time swapping the siamese scale/wood hybrid to each wheel in turn and using the resulting free wooden block to replace the scales on the corner you just did. Simples! Accurate and VERY cheap. This would give you the ability to go to (in your scales case) 800lbs per corner.

[@thomaswomack3888]

good idea - there are scales available for reasonable money now that go to 550 lbs so two of those together gives you 1100 lbs per corner that would be sufficient for many normal cars and overkill for most race cars. cheapest corner weight setup on amazon is like 850 bucks. You could do a total 4 wheel setup with a pair of scales at each wheel for half of that or less. Or make only 2 for half as much money

[@danc2700]

Tutorial on how you made your badass chair? :D

[@ateamfan42]

This is super cool. Definitely seems workable to measure one corner at a time if your goal is just to determine total vehicle weight. To do actual corner balancing, being able to measure all 4 corners simultaneously is a nice advantage however. One can probably get an entry-level corner balance scale system for less than the cost of 4 of these rigs.

Or, if you don't need super accurate 4 corner weights, go to your local CAT scale for tractor trailers. For a vehicle that you have to trailer, just weigh with and without the vehicle. $13.50 per weigh, goes down to a few bucks if you weigh again within a short time frame

[@webkris]

Genius idea Matt! I'd say "post links", but we would probably buy out all of the ebay ag sellers in a hot minute. "Livestock scale kit" is all you need in a Google search people. You could get a SET of decent dollies and the scale kit for one of them and still be under $1500. 👍

Having built a similar device using the same load cell kit and a harbor freight daytona dolly jack i can confirm it works great. Just make sure to not use the little metal spacers the instruction manual says you must use. Its lying to you

[@mattsmash93]

You could have just gone to a truck stop. They generally have scales that will give you a total weight, front weight and rear weight for like $15. Also, seeing as how cattle can weight 2,000lbs each, the agricultural load sensors should be rated for about 2,000 lbs for a set of four.

I came across the same problem when I just wanted to see how much lighter I could make my rallycross car. My solution, which I have yet to implement, was to get a 600lb livestock/hunting hanging scale, suspend it from something like an engine hoist and pick each wheel up with it. And use a pulley to double the weight capacity if needed. I can jack up the other corner of the car to level it for better accuracy.

@@The11901 I had to look it up. OK, it's a location where I take my car to get weighed. I have a not-road-legal offroad WRX, though. I would have to trailer it there, then weigh everything I then add or remove.

[@The11901]

@@DustyWall assuming you own a truck and trailer… still seems like the easiest route. They’re at basically every truck stop. I almost did what you did for a rock crawler truck and then I remembered semi truck scales exist and generally have to be pretty accurate. 🤷‍♂️ seems like a solution our boy super fast mat didn’t think of. Typically you can measure axle weights too, I think they have 3 “zones.” Can’t do corner weights though.

This is not the cheapest way to do it. The *true* cheapest way to do it: set your tire pressure the same all around, and know what that pressure is. Put a piece of paper under each tire and spraypaint around the tire, then pull the 4 sheets of paper. Measure how many square inches of paper are unpainted, because they were hidden underneath the tire. This is the contact patch of the tire. Multiply the contact patch by the PSI of the tire, and that's how much weight is being supported by that tire. If you have your tires at, say, 30 psi and your contact area for a tire is 25 square inches, then that tire is supporting 750 lbs. Total cost: 4 sheets of paper, 1 can of spraypaint, 1 tire pressure gauge.
