Are the sear screw threads stopped so that when you tighten them, it doesn't crank the bridle down on the sear?  Having excess threads is a common problem.

To me, nothing looks worse on a flintlock rifle than screw slots cut on on milling machine. It looks mechanical and modern. Cut them with a knife file like the old timers did. Also, modern filister type screw heads look awful to me. I at least chuck them in a drill press and round them off a bit. Just my opinions.

Sorry I missed this Dave. Tim Crosby actually started this thread for me so I wasn't being notified of replies here.

Yes, I shortened the screw threads on the sear screw so it doesn't clamp the bridle to the sear. I shot for a .010 to .020 gap between the screw and the bridle. Of course this may vary somewhat based on your castings, who built the lock, etc.

Thanks for your question!

Dale, I would be happy to send you unhardened screws that you could slot if you like. In fact, if there is a demand for it I'd be happy to fulfill it.

Best,

All it takes is a 6 inch knife file and a few swipes. I would imagine anyone capable of  building a long rifle could do it in a few minutes. If I am doing a fancier gun I use the screw head files from Brownell's. They aren't cheap but probably a little bit less than a milling machine. I sure don't mind doing them on  my own builds but the prospect of a bench full of screw blanks needing slotting doesn't sound real entertaining!

Chris - any chance you are going to do another run of bridleless Chambers colonial locks?

I get asked that quite often, so maybe I should take that as a call to action! Truth be told my lock production has been way down as machine shop takes on more lucrative work.

If I do end up doing another run (they've always sold well!) I'll let everyone here on the board know.

Thank you,
