    Sorry no updates. I've been getting ready for winter, finishing little "honey do" jobs before the snow flies. I'll get back to it soon.....I hope.

    Thanks for the tech and pics. This should help when I build a champ style out of a 3/4 ton rear.

    I've got 3.78:1 ? gears and the change gears I have will give me about 3.5 high and a 4.1 low. I'm using original gears.

    How did you do the pressure angle on your splines,15degrees ? Make 2 extra cuts in each spline? beautiful work by the way.

    I made all my cuts with a carbide 5/16 2 flute end mill. I found a centerline and with the cutter @ 90 I went up half the width of the spline and made light cuts till I got the right depth then went to the other side of the shaft and did the same thing. The splines are straight . the gaps are 60 degree. I cleaned out the center with a 3/16 cutter to take down the center ridge .

    My lingo may not be correct I'm a self taught home machinist....I've ruined a lot of metal getting to here.

    A bit ashamed to say that I haven't accomplished anything lately. I got a new pinion bearing and pressed and torqued it into place. Other than that not much new. Still dreaming up a design for a rear cover that I like. The other one didn't float my boat.

    To the fellow that commented on winters units having a steel ring gear backload bolt,yes the bolt is steel but there is a bronze "cap"on the end of the bolt so you don't have steel rubbing on the back of the ring gear..."Jethro ,Awsome work,are you considering selling a "kit " of parts for do at home guys?

    I hear ya. i haven't given up on it, just real slow progress. I'm making up a pattern for the rear cover/housing and keep running into design issues. I've never made a foundry pattern before so I want to get it right.....and I'm slow( not challenged just taking too damn long)
    King ford......I may come up with something like that in the future , maybe my retirement job.

    Jethro,
    Thanks for showing us your work. You have inspired me to attempt my own quick change. One question....Where did you find the Air Liquide "magic" welding rods? Ive scoured the net and can't for the life of me find them. Any
    help would be greatly appreciated!!

    I picked it up at a welding supply place ...I was told later that it is some kind of stainless alloy but not sure what the composition is......I'm afraid I'm not much help......good luck with the QC project....keep us in the loop , let us know how it goes!
