Well been kind of slacking not on the build, but on posting. It has been slow going, due to having to spend a lot of time on the lathe. I have gotten both stub axles welded up and have finished one side of the inner CV cups. The majority of the parts that I have been machining were hardened. So, on my small lathe that meant using Carbide bits and only being able to make small cuts. First I had to turn a shoulder on the inner VW CV cups so that they would match the inside diameter of the Joyner cubs. Then I had to make a centering jig to align both cups. Luckily I had some good turning stock on hand to make this, since it required quite a reduction in size.

Then I had to reduce the width of the Joyner cup to match the axle length. This was a real pain, since not only was it hard, but as you approached the inside diameter it had grooves for the CV balls. So when you have a hard material and voids in it, it is very hard to turn (can we say chipped bits). Once the jig was made however, it welded up nice and true. So now it is time to mock up the passenger side, then I can double check for travel and then determine how much to cut off of the other Joyner cup to match up with my other axle.
