Hi All, I'm curious about what methods people use to repair stripped screw holes on plastic piccolos (and clarinets). I have a plastic Gemeinhardt on which the rib was partially torn out of the body, thereby pulling 2 of the screws out and stripping the holes. I'd love to hear your various methods of dealing with this type of problem.

P.S., thanks to everyone for your contributions to this site; it's a phenomenal resource that I've learned much from.

Thanks,
Marco

Marco,

On wooden instruments, I would use grenadilla dust and super glue to fill,
and then redrill. Many plastics get brittle around super glue, so I would have
to go with my second choice, which is epoxy, preferrably the longer setting,
harder variety. Then, redrill to tap size, and let the screw form the threads.
A slight bit of heat on the screw might help with this, but you don't want to
goober up the epoxy, which won't take much heat. You could also cut a
vertical groove in the screw with a dremel, so it acts like a tap, if needed.
You might also add a bit of epoxy to the underside of the ribbing when
replacing it.

Thanks for the info, Larry. One thing I wasn't quite clear on: When you use epoxy, do you also use some sort of dust/shavings, or do you just fill the hole with epoxy?

Thanks again,
Marco

P.S., I've watched all your videos and learned a lot from them. I'm relatively new to this trade, so it's great have so much good info available.

I've just used the epoxy straight. But yes, you could mix in some plastic
shavings or dust. If a good hard epoxy, it should go well. The Armstrong
brand is very good but is white in color. You could color in after it hardens
with a magic marker. It's available from some of the suppliers, maybe
Allied? I usually just use whatever from the hardware store. The longer
setting epoxies tend to harden up better.

Thanks Larry -

The 2 hour epoxy that I had on hand worked great.

Take care,
Marco
