drive shaft shortening

I installed the slip yoke on the end that already has the right size u joint.

Next I have to liberate the end of the shaft so that I can weld it on later.

by the way, the tubing is .095 wall which was heavier than I expected.  Next I need to separate the steel tube from the casting.
I assume that the shoulder under the trunion is parallel to the u joint axis so I lined the part up based on that:

Then I machined through the weld.  You can see the rust peaking through right as I started to get through the tube and expose the casting:

Ready to weld with a beveled edge:

My u joint came from Amazon to convert from 1 3/16 to 1 1/16.  

Once I had all that together, I would see the distance from the beveled cut to the very end and see where to cut the tube.  I scored it with the cutting disk in the die grinder then finished the cut with the 4 1/2:

Then I heated the end of the tube up with a map gas torch and beat the u joint in.  I used a piece of angle to line up the Ujoints at each end.  I wasn't sure how close the had to be.  A co-worker told me .125° or there would be big trouble.  The internet doesn't seem to agree.  Seems like 5° is common, which I am more inclined to believe (maybe because I have to!)

Here is the end stuck in the transmission.  Pretty much right where it used to be on the yoke:

Here is the end into the pinion.  Looks good.  Not a lot of clearance on the e brake cable

Just need to weld it up
