Does someone make/sell super thin cork for soprano, or is it just a massive sanding game?
Both my curved and straight have very thin corks which makes me think they will need more frequent replacing, this the ask. Looks like music clinic goes quite thin in their assortment. Mouthpiece fits well on both.If 1/16" cork which is the standard size for neck corks is too thick, the next size smaller is 3/64" which is often used on clarinet tenon joints. I wouldn't recommend going with anything thinner than that for a neck cork unless you have a very unusual soprano or mouthpiece or both. If you have a caliper you can measure the diameter of the tenon at the end and the interior diameter of the mouthpiece shank. Subtract the two figures and then divide that by 2. That will give approximately the thickness required. Add a small amount to that measurement to allow for a bit of compressing and you have the thickness of cork to start with. Remember that as you move back from the end of the neck it requires a bit more sanding to compensate for the slight taper. Ideally the finished cork needs to be cylindrical, and fit so the mouthpiece can comfortably go all the way to the end with a bit of twisting and pushing.
