Thank you very much.  I've been trying to shoot more video, trying to get better at editing, etc., with an eye towards doing more of a video blog for the "Build Diary".  If you like it, please subscribe to my YouTube channel.

I got the engine started for the first time since last fall.  It has a new transmission, shifter, flywheel, clutch, pressure plate, trans mounts, etc.

There are now 4 VW starters in my garage.  Only one is the "right" type starter for this application.  The mix & match of parts on this truck are sometimes difficult to keep track of.

The latest update:

My friend Darrell and I spent an evening cleaning up the interior of the Rampage, then taking a good look at what it's going to take in order to link the VW 02A-based transmission to the Plymouth Acclaim drive hubs.  Anyone who has ever worked on a CV joint knows how filthy and nasty they are inside.

Here's the video:

Nice progress, Steve.

If you do weld those two axles together, I'd suggest cutting the sleeve ends at a diagonal or use a "fish mouth" cut. This distributes the torsional stress over a larger area. A circular weld concentrates the stress at the weld.

Good thinking on the fish mouth cuts.  :cheers:

 It just so happens that I have the tooling to make cuts like that.

Steve,
Once you have determined the shaft length then make the sleeve that you are going to connect the two shafts with ,003-.005 smaller than the shaft's OD and heat the sleeve and freeze the shafts and then and shrink on the two shafts together  then TIG the diagonal joint. This does several things, it insures exact alignment of the two mating shafts (at least as close as your lathe can turn the shafts and sleeve) plus the shrink fit will greatly increase the torque capacity of the fabricated shaft. You won't depend completely on the TIG weld for carrying the torque load.

Rex and Freud - excellent advice all around.  I may make 2 sleeves - one for mockup to determine the exact "best" overall length.  This sleeve would be slightly oversized to allow a telescopic-type adjustment.

The second, and permananent sleeve, would be a shrink-fit as described above. 

I am very fortunate to work in a facility with qualified machinists and some heat treatment capabilities.  This will be work for our CNC guy.  I can do rough cuts on our manual lathe, but the ability of that lathe to hold tolerance, and my ability to operate it effectively, are far from ideal.

What do you guys think about pinning the sleeve to the shafts in addition to the shrink and weld?  In my own mind, I have gone back and forth on that topic.

No likey.    GIANT stress risers, potential failure point.    Those axles are just "torsion bars" and the welded section will not "twist" at the same rate as the rest of the shaft, raising the stress on the remainder of the shaft, concentrating the stresses on the welds.    We used to weld things to anti-roll bars to stiffen them, and it was a "wild ride" when they broke . . . . . . .  always at the weld . . . . .

Steve, what are the consequences if this welded shaft fails in service?    Is there the potential for catastrophic damage?    To the car?   The driver?

Wouldn't a purpose made axle be a better choice?

Maybe I'm way off here, as I don't follow your build that closely.    BUT, I am a safety first guy.    I've lost too many friends to "stupid sh*t.

Just my 2ยข

WOW - thanks for pushing on getting this site to do video links more readily.

I'm not a machinist but I stayed at a Holiday Inn once. I don't think it would be that expensive to make a new axle out of the right material, the right length, with the right ends, especially since you have access to machining and heat treat. Do what you're thinking to get the proper length, then make new = much safer.

YMMV

Those are all good ideas. 

My first chore is to get a mock-up made to verify the correct working length of the shaft for this application.

After that, I'll have some decisions to make.  In the meantime, I'll research custom FWD axles.

Our shop "may" be able to do it, but we don't have a good way to spline shafts.
