Strange, I'm not seeing any parts.

You want parts; we got parts! (No fair looking for the mistakes...)

Looking good Mike

I went to make some brass ones today and noticed that the knurl wasn't cutting correctly.  I pulled the pins, as the wheels  had a lot of radial run out and noticed that both are soft crap steel and badly work.  It is one of the cheap arse bump knurlers that come with the AXA QCTP kits.  Guess I will have to bump the camjack knurler up to the top of my project list...

When you get around to the knurls, check out these guys:

Thanks Mike - some useful info in their tech section as well.

Now if only Ed would get on with his drawbar hammer, there would be something else to show in here...

You better pull your finger out Darren and make some tools

Unfortunately, other things are taking priority right now

Nice work on the knurler.

This project has been on my "to do" list for a while now and one day I will get around to it. I followed Tom's video of it and that inspired me to at least get the materials. Maybe I need to watch it again and it will motivate me to move it to the top of my list.

Mike.

  I'm in the same boat!  I hope to be in the shop all day, too cold to shoot skeet!  Today I'm making a "simple" project, aluminum jaws for my Wilson bench vice.

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.

Tom

I'll give it a shot, Tom. Thanks for the great project videos!
