well it's looking good. After fitting the first screw on the bayonet adapter, I realized I needed some sacrificial ones - they are #10 x32. Fitting them snug against the harder barrel steel wears the threads. If anyone reads this, get a box of stainless screws as you will get more trials out of them, and save the original screws for the final assembly.

Time to blue everything else, and I haven't worked on any of the wood yet. Need to make a final pass at squaring the crown up too.
