    After adding some new springs and larger tires, my old beat-to-death stock drive shaft was starting to show some splines. Since I'd rather do something myself and make it the way I want, than pay someone else to do it- I decided to lengthen it myself. /forums/images/graemlins/thumb.gif

    Here's a few pictures of the progress so far-

    This is the splined end of the shaft. After cutting the old tube off, I machined a shoulder into it to be pressed and welded into the new tube..

    This is the yoke end of the shaft. I couldn't figure out a way to get it chucked up in the lathe to machine it perfect- This is the facory machined surface after cutting the old tube off..

    Old stock driveshaft tube on the right, @ .069 wall, new drive shaft tube on the left @.250 wall.. /forums/images/graemlins/eek.gif I'm going to machine the I.D. of the new tube to match the O.D of the yoke and splined ends of the shaft for a tight press fit, then weld it up.

    As for balancing, if it's needed, the old shaft had no balance weights, I think I can accomplish that with a hose clamp around the shaft, some weights and trial and error. If all else fails, I'll send it out to be balanced. But I think it would be pretty damn cool to make it all work myself. /forums/images/graemlins/pimp1.gif

    Nice, you have access to some cool toys. I'm sure you can make it work with a start like that. I've built several shafts that work fine (several fronts, and a few rears) and I don't do anything but cut the tube off, then tap the ends into new tube. On some of the fronts, just cut, sleeve and weld. I wish I could do work like that! /forums/images/graemlins/thumb.gif

    Don't forget to install a driveshaft safety hoop. If the front u-joint breaks, and that 1/4-inch wall tube digs into the road, it'll pole vault ya into orbit! /forums/images/graemlins/eek.gif /forums/images/graemlins/wink.gif

    I second the hoop idea. That is a super cheap mod that yuo may never need...but if you do...you are a GENIOUS.

    I did one a couple of years ago...
    I tacked every thing together...
    bolted it-up to the truck...
    indicated it...to make sure it was close...
    pulled it back off the truck...and completed my welds...

    Looks Good!!! /forums/images/graemlins/cool.gif

    Hmm, If the u-joint at the t-case breaks, the shafts falls to the ground- What does a high angle CV have to do with it? /forums/images/graemlins/thinking.gif /forums/images/graemlins/1zhelp.gif

    I think he thought you were doing a front shaft.
