🍆ing around Part 1: Stripped female thread on optics cut

[dickasauraswreks]

I have a garage full of tools and too much time on my hands so I picked up a rmr cut slide with stripped female threads in the posts and am going to attempt to fix it. The ways to fix it range from janky to super janky and I was wondering if anybody has first hand knowledge on what the best options are.

So far I've considered:

JB weld and retap: will work but is it strong enough? Find out next time on dragonball z (maybe)
Brazing: not really feasible since you have to heat up the work piece
Mig welding: maybe? not sure if I'll be able to get the wire down into the bottom and if the posts will last.
Tig welding: yea but will lose the posts.
helicoil: same as tig but easier.

I would suggest trying JB Weld and test thoroughly.

If that fails, you still have the other options remaining.

If JB Weld doesn't work, I would personally try Helicoil.

I would use a timesert before helicoil. if they offer one small enough

Superglue+baking soda?

If you garf up the 50/50 mix on JB weld, it can be crumbly/brittle. Ask me how I know.

Given the choices you've proposed I'd suggest a skilled gunsmith before things go any further south. Mark Twain supposedly once said the quickest way out of a hole is to quit digging.

Would superglue and maruchan ramen work?

Bad news guys USPS may have lost the slide. We may never know.

Might actually be good news, leave it to USPS to muck things up. Currently I'm dealing with 2 items that were supposedly delivered but weren't.

I've had really good luck with them, but it is coming from florida so I' giving them a pass on account of the hurricanes. Fedex has always been the one to avoid for me.

Yes, I have first hand knowledge repairing a whole lotta stuff. You said you have tools and time, so there's no excuse not to do it right.

Go to your screw drawer and find something a little bigger diameter than the stripped hole. A fine thread would be my preference. Stainless would be ok. Drill out the slide and use a bottoming tap on the new hole. Be careful not to drill into areas you'd best not drill into. Clean everything perfectly. Use some retaining grade Loctite on the screw, and then tighten it into your new hole. Now cut off the screw so it's flush. You can use a Dremel, hacksaw, file, milling machine, or whatever you want. File it flush. If you want, you can peen the edge of the slide/screw to better lock it into place. Next step is to drill and tap the screw/bushing to accommodate the original sized screw. Put a little countersink on the new threaded hole, and stone the surface so it's beautiful, and you're done.

This isn't a particularly difficult repair as long as you take your time to measure everything perfectly, so the screw and the new hole are exactly where they should be. Take your time as to not break any drills or taps.
