Anybody got a liner milling jig like Tony Bose uses? Trying to figure out what parts are threaded, how the pivot pin locks in, and a few other things I can't quite tell from his tutorial.
 
Heres a pic of the one I use- gets bolted to the tooling plate on my mill 1/4-20 bolts, 1/2" mild steel
stock. The small bolts are 4/40 to hold the pivot, and 6/32 to hold the liner. Hope this helps.
The pin at the top is not threaded and is held by the 4/40 screw from the side.

Thanks, Ken. Exactly what I was looking for. So, the pin through the pivot hole in the liner has a head soldered on, and is locked in place by the set screw on the base block? The liner is also held on by screws threaded into the moving plate? I notice a similar setup on the other end, presumably for a different size pivot pin?

Correct- head soldered on the pivot pin, and locked to the base block with the 4-40 set screw, yes the one on the end
is for smaller knives with a 1/16" pivot pin. liner is held on to the moving plate. That 1/4" -20 screw is actually countersunk
as is the one you can't see under the moveable arm
