I'm cutting the feed ramp now...
1st pic - I center the [stripped] barreled action in the mill vise, and set it to what I think is the desired angle...
2nd pic - I've eyeballed an old P-08 9mm barrel throat, and made my cut with a 3/8" end mill...here's the result...
3rd pic - Barreled action has been reassembled and weapon is fully functional once more

...Sharp chamber edges still need to be smoothed out; tool marks on outside of front barrel band, rear sight 'sleeve', and rear sight base need to be draw filed or sanded, and the rear sight itself needs some more work...but it
should feed and fire now...
I'll reload some dummy rounds (no powder/primer) and see how it cycles...Might have to adjust the feed ramp angle...
...But in one of those annoying occasions, I can't find my 9mm shell holder...

I'll have to get up to the local sporting goods shop and get another one...
I have 5 or 6 hundred 9mm rounds reloaded, but they're loaded hot for my S&W 659...I don't want to chance blowing the ejector through the breechblock, so I'll wait and load some light rounds to try this booger out...
