Hi everyone,
I am currently learning how to reface clarinet mouthpieces.
I can now flatten the table, thin the tip rail pretty well, and can make a decent looking baffle. However I am having trouble with constructing a proper clarinet mouthpiece facing. A clarinet facing is supposed to look like the one on the bottom in the attached file right? The one on the top one is the actual measurements of an mouthpiece of mine, so what I've tried to do on the bottom is to imagine what the top is supposed to look like without the low spots in the facing. Can any expert mouthpiece refacers help me out? Is that what the facing is supposed to look like? Have I fixed it?
Cheers,
Harim

I started that Yahoo group 15+ years ago.
A smooth curve would be better than the wavy one. You should also include the tip opening on your plot. Put the tip opening in the feeler size column and use a glass gage reading of zero if you measure at the very tip or ~1 if you measure inside the tip rail.
There are many curve shapes that work well...and many that do not. Start by measuring and graphing as many mouthpieces as you can. Then note the shapes of the ones you and other players like vs the ones that are not great.
I also think it helps to measure finer than the nearest whole number on the glass gage. Try for the nearest .5 at least. I go to the nearest .1 but I have great close vision. You do not need to go this fine to do good work.

A great deal of the discussion at MouthpieceWorks is about sax mouthpieces, although clarinet issues are brought up from time to time. For me, this begs a question: are there different issues with sax facings vs. clarinet facings?
Obviously, the numbers are different, but are different curve shapes more popular or do some work better on a sax mouthpiece vs. a clarinet mouthpiece? I've read a number of posts from Keith Bradbury and others about the geometric characteristics - the rates of curvature at different points of the facing - of the sax facings they've developed. I never really read much about different curve shapes here or on the Klarinet list with the possible exception of the curve as it opens very near the tip. On the other hand, I've seen lots of discussion here about deliberately asymmetrical facings and I don't remember reading much about them with sax facings. Am I just using selective memory, or are the concerns very different?

Thanks for the advice Keith, I really appreciate it!
Yes I think that classical/orchestral clarinet mouthpiece facings are different to most saxophone mouthpiece facing shapes as we need more resistance, or 'something to lean onto'. But I'm pretty sure that classical saxophone mouthpiece facings are the same shape as classical/orchestral clarinet mouthpieces as they need a bit of resistance as well.
I have read a few posts on this board in regards to clarinet mpce facings and most describe the curve as what I've drawn up on the graph. I haven't been able to put in the extra sharp curve near the tip of the mouthpiece which is usually there but I think I've got the general shape of it.
Can anyone confirm that what I have drawn on the bottom graph is indeed what the original classical clarinet mouthpiece intended to look like?

Ooops! I didn't realize Mojo *is* Keith Bradbury.
Sorry, Keith, I lurk on Mouthpieceworks a lot, since I don't have much to contribute of my own knowledge, but I'd never paid close enough attention (apparently) to who is who.
