Where are we with Gunsmiffin?

Got a fair bit of big things done.  Barrel fitted, link fitted to barrel, ejector, firing pin, and extractor installed and tested.  Barrel ramp and frame ramp polished a bit.  Dremel work, but not as hard as the carbide bit stuff.

What next?

Gotta prep the fire control parts.  Leaf spring, sear, hammer.  At least the parts I can't mess up.  This part is hard but it's an intellectual difficulty.  And the results are pretty binary.  Either you stoned the sear and hammer hook right and the gun funtions 100% or you didn't.  There is no 99% is ok.  And there are major safety issues.  Too much off in this spot and the gun goes full auto.  And not in a good way.
