Hi all
I aquired a Selmer HS* crystal that I am starting to like quite a lot. I have been trying to get back into a glass mouthpiece and off my old Bay. I was mainly after an O'Brien, but since they are so scarce I have been trying anything that was made by O'Brien. I have tried many Pomirico's over the years but could never find one I liked. Seems the only (main) place to find these MPs that were made years ago is on Ebay. Anyway, this Selmer HS* Clarion crystal is playing very good for me (from recording to compare with my other crystals). The problem is it has a couple of tiny chips on the tip which does not seem to be a problem until after I play it a while. After a while I can hear a distorted sound in the tone similar to getting to close to a fan but not quite that bad. I really do not want to remove more glass off the tip at this point as that would modify the tip opening. I would rather find a way to add some kind of clear material to the chip and sand flush with the rest of the tip. I was reading somewhere that a tiny drop of super glue could be put on the chip, let dry and then sand flush with the rest of the tip. Anyone know the best way to repair these tiny chips?? Also would like to find a couple more Selmer HS* Crystal Clarion mouthpieces!
Thanks Very Much
Jim

There is a Yahoo group on mouthpiece facing and repair. It's called Mouthpiecework, hopefully this link will take you there.

Good luck.

Jim - If CG's link doesn't get you there, try"MouthpieceWork@ Yahoogroups. com" . Its a quite-tech group of mp [facing] workers, more sax than clarinet, so little may result re: our glasses. I once broke [severely] a VG glass mp, took the pieces to our [chem] laboratory expert glass blower, who said "no can do", more? because it was a "high lead glass" than the time needed to put Humpty-Dumpty back together. I also [somehow] put a 1 mm dia chip in another glass's table at the "wind-cut" which I "fixed" with a drop of white epoxy, shaving it to flat with the table. It has held in with playing and is good as new, IMHO. A chip in tip sounds formidable, if a "gluing-in" followed by refacing the repaired area isn't satisfactory, a "melting-in" MIGHT work, again with a slight reface. Glass repair may get expensive! At this time a Sel glass #3 is bid up to $52 on EBAY [delete if not OK, GBK/Mark] so look at options. Rots of Ruck, Verbose, again !! Don
Thanx, Mark, Don

Thanks Don, I just tried it again to see if I could make it do the wierd distort sound again. It played like a champ with several different reeds, big loud clear sound and playing in pitch with a Korg tuner. This puppy will go up in the altisimo (double high C) with ease. I don't think Ill mess with it, I was just worried that it would act up on a gig. If it ain't broke, don't fix it! I'm also going to keep up the hunt for a couple more Selmer HS* Crystal Clarion mouthpieces!
Thanks Contragirl but could not find anything at http://groups.yahoo.com/group/MouthpieceWork/ of any help.
I will be interested what Dave S has to say.
Later
Jim

Igor Miles Stravinsky Davis (er, I mean DS) here: The way I repair chips in crystal mouthpieces is to clean the chipped area with acetone solvent, then quickly fill the chip with a bit of clear epoxy (preferably the stronger, slower-setting variety, as the "5-minute" versions never really harden sufficiently). Overfill the chip slightly with a projecting mound of epoxy. to allow for shrinkage (which is significant in the first day of curing). Wait a couple of days, then sand the epoxy flush and reface the mouthpiece.

I would be concerned about whether epoxy is toxic.
Perhaps your dentist knows of a good material.

Epoxy is a polyamide resin --- perhaps Dr. Omar can answer definitively, but I would doubt it's toxic, especially in the miniscule quantities which might leach into our systems over time.

Might as well worry about putting reeds in your mouth.

Yes, or the mouthpiece itself, which is made of a polymer as well after all. (For that matter, eating antibiotic-fed turkey, chicken or beef may be more dangerous to your health!)

Thanks all for the info. Dave I am printing your response as it was exactly what I wanted to confirm. This mouthpiece has only done the wierd sound that is hard to discribe twice. I have never had a mouthpiece do this unless you stood very close to a fan which is a no-no. Beware of playing in night clubs and having fans on the stage to help keep the band comfortable. Its not that bad but its the only way I know to discribe it. Anyway, the last time I played it (soft, loud, high, low, fast, slow) trying to see if it would act up, IT DIDN'T. So for now I'm going to use it as is. Thanks again Dave.

Once an appropriate epoxy has thoroughly "cured" (all cross-linking is completed), I would not be concerned about licking it. While I don't make it a habit of doing that to small watercraft, old Chevrolet Corvettes, or one-piece shower stalls, I wouldn't expect it to be fatal.
Regards,
John

I repaired a large gap left by a missing chip once - about 12 square mm at the tip of a hard rubber mouthpiece. It lasted years, and as far as I know is still going.
I would definitely head for superglue for a crystal mouthpiece, because it sets to something far harder and rigid than epoxy, more like acrylic.

Just throwing out an idea without any supporting knowledge. May be worth looking into. I don't really know anything about them, but I know there are some kind of kits available at auto parts stores that are supposed to repair cracks in windshields. For what it's worth.

As far as I know these kits are for filling cracks, not chips, with a very low viscosity (hence wicking into the crack) clear cyanoacrylate glue having the same refractive index as glass. If so, they are probably not suitable for use as a filler.
