With simple tools and a lot of patience, you too can make or modify your own driveshafts at home.

If you get an A4 piece of paper and wrap it around the shaft. Line up each end of the page you will have a perfectly round line to cut off

Your spring loaded end was a good idea to keep tension, but the cone was loose enough to impact your dial measurements. If it was threaded on without the spring and tight you would get much more accurate measurements

You are right there! I am still running this shaft with no vibration or issues yet... But in hindsight I could of done things better

So if you want to do this and keep things as straight as possible first clean paint off of the shaft. Use a pile cutter to cut the shaft to keep the cuts straight. Use 2 pieces of angle iron to clamp the shaft in a vice. Weld short distances on opposite sides of the shaft between gaps in the angle iron. Move the angle iron 90 degrees and repeat. Then finish the welds. The pipe cutter will not only give a straight cut but will also slightly bevel the tubing and give a bigger weld surface and a flatter weld. Make sure you check runout and correct it with selective heating using a torch. A mig welder will often give a nicer weld depending on your skill level. Another way to weld it is in the fixture slowly turning it using mig after placing tack welds using the angle iron. Again check runout at the end.

Great tips. If I did this again I would use very different tools (lathe and mig welder”. But at the time it’s what I had and this shaft is still running down the road

Welding isn’t special it’s like 50 bucks at Harbor freight. I think if you’re trying to make a driveshaft a welder is expected to be needed

Nice. I have an aftermarket Camaro shaft that broke the back apart when my 10 bolt broke. Can probably use that with an explorer shaft for Beretta. Hmmmm.

any new info on this? Can't believe balance was NOT an issue, Awesome!!

@spankranchgarage 3 ай бұрын

Still running great. Balance isn't an issue on this particular car because it has a 2.81 rear axle ratio and ~ 26" rear tires. At highway speeds this shaft only sees 2500rpm or so. You can get away with a lot at those RPMs. For the same car but with a 4.10 rear and an OD trans, balance would be much more critical.

How do you make your drive shafts stronger to cope with extra torque Let’s say you’re thin?

@spankranchgarage 2 жыл бұрын

You could sleeve it I suppose. But the best option is to cut the stock tube at the ends and order a complete tube with thicker wall from a driveshaft supplier

Really shouldn’t butt weld driveshafts together. Especially for people who don’t weld very well. I get so many in my shop that get tossed out vehicles and sure enough it is almost always the butt weld that fails. Luckily you didn’t need to phase this one but most would require it. The run out on stock tubes is also horrendous so lining these things up outside of being on a center is next to impossible. Glad it worked for you but it’s just not something I would trust with how often I see these break.

@spankranchgarage Жыл бұрын

This is some good stuff I appreciate the comment. Knowing what I know now I would of done this differently but this shaft is still running great. It helps that this car runs a 25” rear tire and a 2.81 rear so the shaft is spinning relatively slow on the highway. Probably why I don’t have any vibration issues. Yes phasing would be critical if it had 2 u joints. The stock tubing is all over the place. I though of making an ID sleeve on the lathe but don’t think it would help much on this tubing.

@@spankranchgarage I have been building shafts for decades so I figure I can try and help when possible. Sorry if I sounded like a troll at all it was not my intent. I have just seen some scary things butt welded together and by the time it hits my work bench it has already destroyed someone’s vehicle. Had one where a guy pressed a square tube inside the round tube ends to center left a big gap and tried to fill the entire thing lol.

No offense taken! I am sure you have seen plenty of hack jobs. If you had this job would you turn the ends down and retube? I’m assuming the ends are not available new

@@spankranchgarage that particular on is special monster. The yokes and other parts are friction welded to the tubing. That makes the process a bit more complex. The first drawback is they are almost always made with obscure tubing sizes and metric as well. That is just an obstacle though which with a bit of planning can be sorted. The second drawback is the type of process they assemble them. The friction weld process doesn’t require a pilot hub for centering as the welding machine is able to center, weld, square, and phase the parts all at once. It’s nifty for high volume but makes any modification a little more difficult. I personally will not butt weld tube together. In my line of work it is unprofessional and would be harmful to my reputation. I’m not saying it can’t be done well or work I’m just saying if you have the equipment that I do it is completely unnecessary and frowned on. My first step is getting the friction welds removed so I can measure the bores in the end piece that needs to be moved. After that, I make a bushing I can weld into the end to give me some sort of hub to recenter the yoke or stub or whatever. The bushing can be whatever size I need so shortening even into the swedged part of the tube is doable. Swedging is how they make tubes with multiple diameters and is popular when you want strength without adding weight. It was originally used in vehicles that needed longer shafts because the larger diameter and lighter weight are able to solve two major issues. First is length. Second is critical rpm. Building a shaft too long is quite dangerous if you use too small of diameter tube or build it too heavy. Anyways, after the bushing is welded in and milled to the necessary spec I can reinstall and balance the shaft where ever it needs. The same method works when they need to lengthened as well.
