Stripped Liner Question
Have any of you guys had to deal with a stripped out hole in a liner? If so, what can you do about it short of making a new liner?
I'm using .050 nickel silver for the liners of my little autos, and I have a hole drilled with a number 54 bit and tapped for an 0-80 screw. Well, it looks like I may have stripped the hole a little because the screw is not holding as tight as it should. I will be using the blue threadlock when I finish the knife, but I would like to know if there is something I can put into the hole to help the screw get a tighter grip. Thanks -chris

NS is somewhat malleable so maybe you could peen a NS rod into the hole, clean it up, and re-drill and tap. Just a thought ...

STRIPPED TAPPED HOLE
CHRIS, YOU MIGHT TRY A SMALL BALL BEARING LAID OVER
THE HOLE AND TAP IT LIGHTLY WITH A HAMMER, THEN RETAP IT WITHOUT REDRILLING. WHERE I WORK THAT SOMETIMES WORK ON HOLES WE WANT TO TIGHTEN UP. ESPECIALLY ON NS. HOPE IT WORKS FOR YOU. LYNN DRURY POTEAU, OK

Did you try another screw? Most times with 0-80, it's the screw, not the threads.

Micromark Tools sells a set of "reducing punches" for repairing oversize holes. I haven't tried them myself, so I don't know how well they work.

That proceedure of Ray's does work well if you drill a hole and use a rod larger than the hole you must drill for taping. So if you drill a 1/8" hole and peen in a piece of nickel silver rod you should be fine. Frank

Chris,
Go to the side of the liner that will face the scale. Take a small punch and a small hammer and tap all around the hole. The hole will squeeze up. Rethread the hole and you are back in business. __________________

Thanks for the help, guys. I ended up using Jeff's method and center punching around the hole and that worked. Thanks again. -chris
