Tilting a Table to Open a Tip (aka Bias Butt Cut)

I show how to open the tip of a very closed tip vintage Selmer Airflow tenor sax mouthpiece. I use a combination of two methods. Tilting the Table (aka Biased Butt Cut) is explained in detail for the first time. Then I finish the job using tip cutting as shown in my previous videos. [Sorry about some of the blurry close-ups. But the info is still good.]

This video has changed my life! I have spent so much money.I have sent so many mouthpieces to refacer and told that they could not be opened up any more.I couldn't really play any of them
I tried this on my Selmer Soloist and it really worked!!!
Keith, you are a Genius !
GREAT JOB Keith. I've done this a few times, it's tricky !
I don't even know how I saw this video, it came up in my side feed.
Beautiful, stay well.

Thanks Mojo, very interesting and informative.......
I didn't use the math or anything but just took a little off the bottom half of the table.Thanks so much!!!
So , when refacing ; you lean into the side with the highest number to flatten the table.
Great vid!
You surely went about opening the tip in a real scientific manner. I have been opening and closing tips but sanding the table either towards the heel or near where the facing starts and have achieved the desired results merely by very cautious sanding using the smoothest paper that would actually cut and finishing by using the back of the paper which removes the very slightest material but does produce a polish. Congratulations on your approach and the excellent result finally achieved. Several players have requested that the chambers of their mouthpieces by enlarged . Have you ever done this type of work? I would greatly appreciate any information or references to links or articles or perhaps books dealing with mouthpiece reworking. Congratulations again on your excellent video and the very lucid instructions and thank you. I wish you the very best.
I show chamber work in several of my other videos. Metal mouthpieces but the tools and techniques are the same for hard rubber. Here is one: ua-cam.com/video/LUY33hiLF-k/v-deo.html
Thank you sincerely for your reply to my request for information concerning chamber enlargement. Yes I did see your video about modifying the metal mouthpiece. I am interested in enlarging the actual chamber of the old time mouthpieces of bakelite to arrive at something approaching the original Sax mouthpiece. There does not appear to be any source from which I may obtain actual dimensions of this monster type piece and the patent has just one rough drawing of the mouthpiece without any internal dimensions or other particulars to offer. Modifying the baffle or adding different types of baffles does not present any sort of real problem and metal mouthpieces do not have enough metal to even form a chamber. I have made metal mouthpieces and one wood piece so it would be merely a matter of obtaining the required internal and other dimensions to enable me to either make an entirely new piece or else modify existing pieces if they should have sufficient material on them. As there are many old time mouthpieces on hand and as the owners wish them modified to have as large chambers as possible, I thought it would be in my own interests to consult an expert such as yourself. If you could indicate or provide a source for the dimensions of the original Sax mouthpiece or something coming close to it, your assistance would be greatly appreciated and acknowledged. Thank you again and hoping to receive your assistance, suggestions, or advice.
I do not know where detailed info on the original sax mouthpiece could be obtained. Dr. Paul Cohen might know. He recently has played an original Sax restored by Music Medic using large chamber mouthpieces. I think he used a Buescher and/or Martin mouthpiece from his collection. Rascher and Caravan mouthpieces have similar designs. One think to look out for when making larger chambers is the intonation. To tune the mid range, you need to push them in farther to get the proper chamber volume needed for tuning. This then makes the palm key as sharper and/or bell notes flatter than when using medium chamber mouthpieces. This could fix an intonation problem or create one. It depends on the sax and the player's embouchure.
Thank you very much for your so speedy reply much appreciated. You are totally right about intonation. I sometimes use a Conn Eagle 75 and the tops are way out. But then the sound over the first two octaves is something to marvel at and enjoy. I have found that a vintage silver Selmer also behaves like this. I am not a professional instrumentalist and have picked up the sax because of the hundreds that must have been worked on by me over the fifty more years i have been into instrument refurbishing. I hate to ask further of you but perhaps you could let me know how i may contact Dr Cohen? Thank you most sincerely for your replies and i wish you the very best.

this is like asmr
Hi nice video as always. What is the final facing length of this piece how do I find it on the chart?
Alvin Cornista My target for the facing length was 48 on the glass gauge (=24 mm). I got that from my experience in measuring a lot of mouthpieces. There are no good charts that give facing lengths. Even when I find a facing length spec my measurement of a mouthpiece rarely agrees with it.
MojoBari so the 48 is derived from the first feeler (which is actually 49 in your final chart)
The theoretical Feeler of 0.0000 which reads facing length of 56 is not used as measurement?
Wouldn't the 56 be the true length or am I missing something here?
Appreciate your reply and much respect for your work
how would you close a tip???
Sand down the table flat or tilt it a little the other way. Then reconstruct the facing curve. See my other videos.
I didn't even know they made an A*. How do you even play that?
Rubbish!! Nothing is wrong with the original tip opening! A competent teacher who has knowledge of both intelligent embouchure formation and how reeds and air pressure actually work can not only play on it artistically but guide any student to do the same. Sell those mouthpieces to those who know what they are doing!!
