Re: Non-Custer Carbines SN check

Good morning Jason,

Yeh, I forgot to mention the often-occurring issue with the firing pin retaining screw. Even worse is the retainer bushing which Springfield used to secure the firing pin on the M1866 "2nd Allin Alteration" which has spanner wrench slots in the head end. And in the case of the M1865 "1st Allin Alteration" you have to contend with that tiny little firing pin screw under the breech block. So, there is a GREAT deal to be said for generous lubrication and occasional removal and cleaning.

You certainly have developed your skill for screw removal, much more than I have. I've been able to remove several hammer screws by using a jig I build which fits into my drill press machinist's vise. Using a brand-new drill bit (I have forgotten the size), lots of good light, and (I think) a #0 "Easy-Out" I was able to avoid damage of the tumbler threads. And I made sure that I carefully lubricated both the screw and the female tumbler thread with G96 at re-assembly. It makes you wonder how the guys at the field outposts managed to keep the guns working.

Best regards,
