Old Weaver Phase 2 with end gear tower

On one of my FAs I put a soda straw over the remains of the screw socket tower.   Then I put a screw in it and filled the straw with epoxy.   After it dried, I was able to unscrew the screw carefully and leave an epoxy screw mount socket enclosed in plastic.

They make  2-56 Heli-coils.

Great question. I've been meaning to ask the same thing.

PrrJim what epoxy did you use?

Usually the long sockets for the screws crack and an helicoil would just spread them wider.  

 

If the threads are just stripped, however, it would be great.

Maybe epoxy 2/56 threaded stock into the mounting holes permanently and cut it to length so that you just use washers and nuts from below?

I will continue to ponder!

you could switch to constant width #2 thread screws instead of the 2-56 machine screws. thread width is a bit wider and may bite into the galled out plastic.

 

some of the Weaver models I have came with thread screws instead of machine screws.

I created new threaded female "holes" in the shell using plastic tubing from Plastruct and a small diameter Mototool grinder. I attached the new "holes" with ACC in the exact position as the old holes. I let dry everything for several hours with clothespins holding the tubing in place. I then created new threaded holes with a self-taping 2-56 screw! More ACC-more setting-and then I carefully used 2-56X1/4 with a tiny spot of white grease and screwed back on the shell! So far, so good. What a pain in the a--!
