    So i'm almost done with my AV8 build and I'm in need of a someone who can shorten my driveshaft, I'm running the torque tube solid driveshaft style. I've contacted inland Empire Drivelines and they can't do it. I know it has to be precise and dont trust my chopsaw and weld back.Thanks Guys

    I had a local machine shop that does a lot of drag cars and they were able to do it. It had to be spray welded to build up the area around the new splines but it can be done by someone good.

    I think I would cut to length and have it re-splined before I cut it in the middle and re-welded.

    I don't believe that those have to be nearly as precise.

    I had a friend of mine (who's a better welder) do mine.

    Cut, chamfer for penetration, use some kind of jig to keep straight, weld.

    Use the splined ends, weld them in a piece of heavy-wall tubing. .120 wall, 2" tube and '37-'48 ends . The same years tube will work, too, if you knock the center bearing out of it. Drill some holes near the ends of the 2" tubing and plug weld them, too.
    Much better, easier, and stronger than trying to weld the solid shaft. Won't need balancing, either, as long as the ends are a tight fit in the tubing.

    I'm having a '39 Merc driveshaft shortened this week. We tried to send it off to Mosier to get cut and resplined but they won't do it for a efficient price. We're going to cut it and weld it to length with a thick walled sleeve around for support.

    Cooks can, but it'll be a little more pricey than Hot Rod Works in Idaho. That's who I'll be sending mine to.

    Take a stock ford coupler, give a lathe turning buddy a case of beer and have him bore out half of it to a slight press fit to the dia of the shaft. Drill out the pin holes on the freshly bored side of the coupler to at least 1/2" and fishmouth the bored end with a grinder. Cut the shaft to length, heat the coupler and tap it on. Let it cool so it stays put, weld around the fishmouth, plug weld the holes you drilled in the coupler. Install driveshaft. Done... No joining two pieces of shaft, no resplining, no monkey business. I'd venture to say that if you have a lathe in your shop, you could have this job done in 15 minutes or less.

    Schroeder Racing Products (of steering box/wheel fame) in Glendale, Calif does it. My friend had it done there. Their number is 818-565-1133.

    40Chevy, you didn't say what town you live in, just California.

    We did my model A shaft by cutting out a section of the shaft out towards the rear end. Chamfered both ends, welded ends together (small section at a time and rotate). After that slid a very snug fitting sleeve about .150" wall and 4" long over the welded section and welded it.

    Didn't need to take the rearend apart to do it. The runout in the middle of the shaft was less then .050"

    It's going behind a mildly hopped A banger so should be fine.
     
  14. I did mine myself using Koz's method. Cut the required amount from the rear end of the shaft, grind new splines with a die grinder, slide on the coupler, weld the coupler to the shaft...... bingo!
    Cost?...... nada.

    Most any quality production machine shop should be able to cut the shaft to length and respline it. It would be something similar to building pto shafts for them.
    It isn't as much as an automotive job as it is a machine shop job.

    if you have access to a lathe, drill the center on one end, turn the other end down to press fit in the hole you drilled, chamfer it press fit it together and weld it up

    Ditto on that... That's how I shorten axles and that's the way my dad taught me to do it who used that technique in the early 60s on nitro-methane FEDs you chop out the section you want gone minus 1.5 inches turn down one side drill the other press back together with minimal tolerance then chamfer and weld... THAT's Traditional.
