Or perhaps this one.

I have all the parts made. I'm waiting for Tom to have the time to do the last (heat treating) video!

Hmmm, looking at the state of your project Mike, you may want to push ahead on your own and finish it up. I had hoped to case harden the parts using a makeshift charcoal forge, but the weather has turned decidedly unfriendly around here and it's definitely an outside activity. The same thing can be accomplished with a torch, although the parts will oxidize more and may require some cleanup on the sides that run in the slots of the knurler.

If you would like to give it a try, get some case hardening compound. You can get it at McMaster Carr, or anywhere that sells gunsmithing supplies like Midway or Brownell's.

1) Heat the part bright red.
2) Dip it in the compound.
3) Continue to heat for another minute or two. Longer means a deeper case, but more surface damage.
4) Quench in water.

The addition of carbon the the surfaces will swell the part a bit, so it may need to be touched up to fit the slots. Wet/dry sandpaper on a plate is all it should take.

The parts look great and if you remember correctly, my parts had an error as well. The trick is to make them work anyway.
