For the manner in which men live is so different from the way in which they ought to live, that he who leaves the common course for that which he ought to follow will find that it leads him to ruin rather than safety.

Triumph Axles, pt 2

Part 1 showed the front axle. Now time for the rear.

Unlike the front axle, where I could use stock that was the proper diameter for the wheel bearings, the rear had to be turned to size. This axle will be a hair over 10.5" long when done. When you're turning a piece that long, and the diameter has to be consistent over its length, it's a good idea to check your lathe. I adjusted the lathe to within .001" over 11". That's pretty good for a 50 year old Logan. The center portion of the axle is .785" and the ends will be threaded to 3/4-20.

Something I didn't show in the front axle post is that you have to align the cutter. These carbide cutters have flats on the sides that make alignment a snap.
Early in the threading process.

I would have rather worked a little closer to the chuck, but the diameter of the axle is ever-so-slightly too large to fit down the chuck shaft.

At the end of the last cut, it's a good idea to test fit a nut.

Here's the completed axle. It looks crooked in the picture, but that's a just the picture, everything is nice and straight.
Now that my axles are done, I have to make the adjusters and spacers. More to come...stay tuned...and all that jazz.
