 Filling Thumbrest Screw Holes
Author: stuper1

Hi,
I have a plastic Buffet B12 clarinet. I moved the thumbrest a bit. I would like to fill in the old holes, if possible with a black material so you can't really see them. What should I use, and how do I do that?

Thanks!!!

You can use black wax melted and applied to the holes with a heated steel needle (which can be removed relatively easily later on if need be), and this can be smoothed down and tidied up using the edge of an old reed as a scraper.

Or Araldite mixed with black pigment - but do try to do as much cleaning up before it goes off.

Has your B12 got a gloss or matt finish?

Thanks for the input. I wouldn't have thought of black wax. In what kind of store can I find black wax? Sorry for my ignorance.

Mind you - candle or paraffin wax will do, so use some of this. If you've got some white candles or food warmers you can use the wax from them.

Even though it's white/clear wax, it won't show up too much once you scrape the top to level it with the joint surface.

Incidentally, Buffet B12s are made from very dark blue ABS resin.

Awful nicks and scars in plastic clarinets can be fixed with a P-Tex candle (used for ski base repairs), but this requires some preparatory work such as masking the surrounding areas with adhesive tape or somesuch. Not worth for a tiny screw hole, unless you have the dexterity to place the droplets precisely where you want them.

For a perfect repair, get a small can of ABS cement (black) at Home Depot, use a toothpick to apply the liquid cement into the holes, it will bond to the ABS clarinet body super strong. It will shrink as it dries, so a couple applications might be necesary, each coat will 'weld' to the previous coat. If you get too high it can be filed, fine paper (400-600 grit)sanded and then polished with very fine sandpaper and polishing/buffing compound, or even toothpaste, in a pinch.

I'm not very familiar with the B12, though if it's plastic, there can't be much risk in taking it to your local repair man and having him fill the holes for you. A repair person can most likely easily fill holes on a plastic clarinet since most are able to fill cracks in a wood instrument which is a more difficult process since wood isn't as easy to work with that plastic. I would give that a try, they can fill the holes and polish them down to make it look like there were no holes there to begin with.

Use a melted black crayon. It will be nearly invisible, and if you ever want to sell the clarinet and put the thumbrest back, all you have to do is insert a hot needle to melt out the wax.

I never thought of black crayon - that should be ideal.

"A repair person can most likely easily fill holes on a plastic clarinet since most are able to fill cracks in a wood instrument which is a more difficult process since wood isn't as easy to work with that plastic."

Filling holes in wooden clarinets is much easier than on plastic ones - it's also getting the finish good afterwards which is much easier to achieve on wooden instruments than plastic ones especially if the plastic instruments have a high gloss finish. There's much greater risk of melting plastic instruments so that makes getting a good finish more difficult. Plus the fact that some adhesives don't bond so well to plastics. Wood is much easier all round to work on than plastic.

I'm not a repair specialist at all, it's a surprise to me that wood is easier to work with than plastic. That's good to know. Thanks.
