A little update: I am now using a 12L14 bar that is exactly the right
diameter. I drilled a hole in the middle with a drill bit and am
machining the teeth right now. I found a couple of bugs in the code,
that I fixed, and so far, it is running OK.

A bug like a rapid move through metal which had not yet been
removed? I got bit by that fairly early on -- a 1/2" sold carbide
cutter (well -- the bottom half of it) bouncing around the room made me
dance a bit. :-)

Exactly.

If the teeth do not exactly mate, I can file them down with a regular
file. I will see how it goes, I have a little extra of this 12L14 bar
stock.

Is this your first machining of 12L14? Isn't it lovely?

Yes, I wonder why it is not available as rectangular bar stock.

its available. years ago, all the parts in my machine shop class were
made with 12L14. When i started making my own stuff out of mystery
metal, i broke a lost of tooling.
