One idea could be to put some green threadlocker (the one that needs heating to come off) on a screw, screw it in and let it set, then unscrew the whole thing.
Not 100% shure this will work, haven’t tried it myself, but it might be worth a shot.
Usually I just do the @eboosted method of using inserts that go all the way through. It does not look as clean but since my dad works I can do these inserts by myself since it is a lot easier to do. I would like to learn how to do actual inserts soon, but I have found that the through the deck ones can actually add a lot of accent color to the board and can even make it look nicer.
Hey a thread about threaded inserts … they are a bitch to me and I hate them … but that’s maybe because I always forget to buy good epoxy to fasten them … so they keep coming out at the wrong end when I try to fasten my enclosure, which creates these nasty bumps under my griptape so I can start over and over again and again …
if your threaded insert was previously epoxied in, you may have trouble spinning it back out even with loctite or jbweld on a bolt. but as suggested all above, that’s probably your best bet. drilling it out being the fallback.
if you know the inserts are already epoxied into place you could try heating them with a heat gun. then using the locknut approach in the video above. but you risk cooking the wood first before loosening the adhesive.
Drill out. Fill with wood plug (heavy on the wood glue) re-drill, add new insert. Had to do just that on my first build, to every hole, enclosure was askew and I just couldn’t. This method worked like a hot damn.
