Baritone Mouthpiece Has Large Diameter Shank Bore.

[1saxman]

The baritone mouthpiece I really like has a small drawback - the shank bore is huge! Its not a case of someone boring it out - its a 'hybrid' with resin body and brass (silver-plated) shank tube, like a Drake. My bari has the Yanagisawa-style smaller-dia. neck. I played a couple of Runyon Quantums on it at first but eventually tried this Barkley 'Hybrid Jazz 8' that does the trick on this bari. I just added a layer of cork to the original cork to try the mouthpiece and I left it like that. I tried a different mouthpiece the other day with a small shank bore so I had to remove the extra cork to play it. That went okay but not as great as I had hoped, so the mouthpiece went back. That left me in an unplayable condition, so I got my stuff out and proceeded to put a new cork on it with the thickest cork I had, probably 2mm. Turned out nice but still a little too thin, but I can use it with some Teflon tape.
So, I ordered a selection of cork up to 1/8". I think the 3/32" will do it. Anyway, the shank I.D. is .745" or 18.92mm. That is essentially the bore of a 12 gauge shotgun!

I got some real limitations as a player and need 2 mouthpieces for my bari.

One to get heard in the big band.

One to come in ppp on low Bb, blending in with the low clarinets.

The problem was with the old Woodwind Co. hard rubber piece I use for the concert band --- very narrow bore compared to the V16 in jazz band.

So I got another neck and have one thick cork and one thin cork.

I got the concert cork marked with a heavy black magic marker ...

When I've had a piece that was an outlier, I have coated the section of the mouthpiece bore that covers the cork with clear nail polish - built up layers until it fits properly. YMMV.

A similar idea to Safesax's nail polish, but I have used some copper foil that is sold for fitting flute headjoints. https://www.justflutes.com/copper-he...ct1356786.html

The foil has adhesive on one side and is easy to cut to size using scissors. It can be a little tricky making it sit flat inside the mouthpiece bore, but I have used it on about four mouthpieces and it works well.

I once had a customer with a mouthpiece bore dilemma so I made an ABS plastic sleeve that firmly fitted inside the mouthpiece.

I do the same thing but with this UHMW tape: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

It lasts a good long time, and I suspect it's a little easier to use than a foil tape.

Neat idea. Let us know how well it holds up over time. It looks like this may be the source product:

This is the way I have done it:

I would never reduce or increase the shank bore on a good mouthpiece. I left unsaid in the OP that I never considered doing such a thing because you don't know if there was a reason it was made larger (or smaller), like to affect the volume (water capacity) of the mouthpiece, which directly affects tuning. So I have to look at all theses 'fixes' as only temporary measures for trying out a mouthpiece in order to take them seriously. For someone who changes mouthpieces from time to time and they have different shank bore diameters, the 'two-neck' solution is best. Otherwise when you change mouthpieces you adapt the neck cork to it.

But the diameter of the part where the neck is, cannot affect tuning or internal volume, because it's full of neck.

As a low impact/low damage fix, you can use cotton puff wadding! sounds crazy but works very well if not elegant. It packs down pretty tightly and doesn't do any damage.

also, thicker vs thinner tefflon of course. Most of what you buy is very thin and you'd have to have a lot of windings..think builds up and holds up better

I vote ABS plastic sleeve.

This is true. The inside diameter of the shank that is on the neck cork can be any size that fits well. It is out of play for affecting mouthpiece tuning. If you happen to make the chamber a little larger or smaller past the cork it is usually such a small change that you can push/pull the mouthpiece a hair to compensate for the change.

What is cotton puff wadding?(!)

Be that as it may, it is a half-assed way to do things. Elementary logic tells us to adjust/replace a cork rather than screw around with a mouthpiece that we like a lot.

True. But the problem is not elementary when you want to use multiple mouthpieces of different bore sizes. If you own one odd sized one, that is the one that should be altered to be like the rest. When I do this, I put my whole *** in the job.

I'm a little surprised that no one has commented on this suggestion of the very best solution!
