A couple days ago I pulled my 1894 carbine out of the truck (it travels with me most places I go) and sat it on the bench and noticed the front sight was missing.  I found the sight on the floorboard of the truck but didnt get lucky enough to find the pin. I pulled a front sight retaining pin off another carbine I had fitted it into the post through the front sight and it started to fall out on its own.  The retaining pin holes through the carbine post are a bit too large.  I believe the pin measures at 60/1000″.  I ended up working down a piece of romex 12ga copper wire to the right diameter to pin the sight and then peen over the copper on the outside of each post.  It holds ok but dont really like how it looks.

 

Any suggestions on how to reduce the diameter of the existing retaining pin holes on each side of the carbine post?  Or is the only option going to be finding or making a slightly larger steel pin?

Chris,

The only way to make the pin holes back to the original size is to drill out and put bushings in them which is a lot of work and you probably see it. The simplest is to get a number drill set or a fraction set and find the right size drill that will press in and use a part of that drill as the pin. You just need a Dremel with a cut off disc to cut the drill. I have done this to make pins for set triggers.

Great idea, hadnt though about using a sized drill bit shaft.  Its likely the easiest solution for the repair. 

Thanks Bob!

Chris,

Coat the pin with Loctite and slide it back in place.

Just thought of another way to fix it.

Take the pin and with a diagonal cutters (wire cutters) slightly crimp the pin off center enough without cutting it of course that it has a interference fit and tap it in the direction so the crimped end goes in last.

I do this to door hinges when the door won’t stay where you put it.  Bend the pin.

I have taken a flat punch and carefully tapped the center of the pin to flatten it enough to snug it up in the hole.  It is also possible to tap the sight hole edges enough to lesson the sight hole diameter.  You can also solder the hole and re tap it to snug pin fit.  Roger
