I went back and "coined" the Rims of previously sized but not turned nor trimmed .25 Stevens size cases and found the Carbide ring did not move further back into the die body so I turned the Die bottom off slightly below the rim of the Carbide ring, leaving the ring about .003" 'proud' of the die bottom.
Post Coining the rims, I am 'turning' them down in diameter using a battery portable drill motor and a Fine cut Mill file. it is time consuming but I can do it at home rather than having to travel to my Friends Special Effects Shop and use his Lathe when it is free.
Today i talked to my Gunsmith, at his shop, and viewed the progress on one of my 1894 Stevens Favorite Actions upgrading the action strength and assembling the parts into a working Action. this entails making new pivot screws from much stronger alloys and the 'sticky point' is the unique threads Stevens used originally, None of them are exactly like modern standardized thread form nor pitch.
This Action is the one with the 'poorer' surface condition I had left with him, and will be 'bead blasted' after completion and before a new finish is applied. The other action has some of the original finish remaining and is not corroded nor scratched so we intend to leave its finish as is.
The gunsmith is still 'recovering from his first Hip surgery and says it will be about 7 more weeks before he is again allowed to drive, so he is walking and riding 'Public Transit' to and from the shop each day.
Best Regards,
