> COMING  SOON  TO  A  TENOR SAXOPHONE  NEAR  YOU !!
> Hello, saxophone players!
> 
> We make every possible effort to listen to you in order to provide products which make playing your saxophone easier and more enjoyable. Players told us that they needed a mouthpiece which enabled them to play and be heard with amplified instruments without being hard to blow, harsh in tone, or excessively bright and thin sounding. After a great deal of experimenting, we are pleased to be able to offer you the Saxgourmet Super Duck Delrin. This Made in USA mouthpiece combines the very latest in polymer technology with precision manufacturing using CNC technology. There is simply nothing remotely like it, anywhere, at any price! As always, when better saxophone products nare needed, Saxgourmet will bring them to you. Please fell free to call me with your questions. Remember, this is the only place you can actually talk with the designer!

Regarding the advertisement on the Delrin MP-  the comments regarding the state of the art CNC machining capability and then a final comment that the facings are then all "hand finished" and play tested.  What I would like to comment and learn more regarding mouthpieces that are made with today's precision machining technology are-1)  With a MP that is properly held for cutting in a CNC machine, a good CNC machine today is capable of 0.0001" tool path precision (higher end machines are even better than that).  So once a face curve tool path program is determined, and it can be very precisely cut why would there be any hand sanding done to it which would very easily introduce imperfections to the true geometry of the cut?I could see MP's produced in high volume whereby the processing tolerances are lax (to coincide with a market price point) having flaws that need correcting, but for a $500 to $800 higher end MP I would expect the MP to be an accurate reproduction with precise processing and tight tolerance expectations.2)  To be able to produce the tip rail and baffle accurately to the face curve would seem to be the more challenging aspect of this process of making a MP, hence the hand finishing would seem to have a roll in this regard.  But if the MP is machined with a 5-axis CNC machine whereby the dimensions of the body, tip rail, baffle, chamber are all able to be cut to the known coordinate reference of the part and program, then again if the MP can be rigidly held so that deflection is negligible for the precision of the cutting tool making it's finishing cuts, then these features of the MP should be more accurately produced.
So perhaps my main question is- what is there about the technology that is falling short of achieving the expected result, and what are the imperfections left that have to be hand finished?Or is there perhaps some defiency in the 3D programming, or cutting tool choice or capability?

 

Very good question. 

I'll be interested in Steve's response; but
one possibility is the presence of "plastic memory" in the finished
product due to stresses in long chain polymers comprising the mouthpiece
material. The degree of accuracy you mention applies to metal items, but
may not be attainable in machined thermplastic items 

Considering
thermoplastic items in general, that are molded out of shredded former
items, small beads, or even powder, the smaller pieces retain a "memory"
of their shape, resulting in internal stresses. Machining exposes such
stresses , for example at a tip rail. The result could be slight
warping. Play testing and touch up could be necessary, even in Delrin,
which is claimed to have "excellent dimensional stability."

it’s true that using CNC technology does allow the manufacture of mouthpieces which come off the machine FAR more accurate and are produced quicker……that being said, remember that the machines don’t program themselves, and that the initial set up is a considerable expense. Also, and very importantly, we have yet to find anyone giving away CNC machines, which are incredibly expensive.

We’ve been doing a good bit of research on 3D printing, and after a couple of years and a lot of different attempts and several generations of machines can now accurately print mouthpieces.

 Unfortunately, although you can print a copy of any mouthpiece you can scan, the economics are currently just not there. The process simply takes too long.

The CNC off brand mouthpieces are high quality and often reasonably inexpensive. Once the tech process gets worked out for the more complex woodwind mouthpieces, it is the design and last little bit of QC and hand tweaking that will set the good apart from the great. There should be better intermediate mouthpieces for much less, soon.
