Well now you have expanded your lexiconI am reading some terminology such as "key benches" that I have never heard before in terms of saxophone adjustment and repair. The terms I am familiar with are the "back bar" from the F# on the lower stack and the C on the upper stack, and the "tops of the key feet" which make contact with the "back bar" as part of the regulation where one key closes one or more other keys.
Interesting. Is the synthetic felt sandable/file-able ? Or some other method-able to thin it ????the material I currently glue to the tops of the key feet is .4mm synthetic felt which I hammer on my jeweler's block to make it even less likely to compress. I used to use thin "techcork" for this application, but found the synthetic felt from JL Smith to be just as stable but even quieter.
All cork except Selmer puts round felt under the lower stack feet, glued to the body, to reduce bounce. Whatever Selmer does is good enough for me. I like to keep a sax as original as possible. The thing is, if you're going to do some corking yourself, you have to know the key opening heights or you can screw up the intonation and projection of the horn.
True...although I regularly use .4mm sheet cork as a regulating material and at times actually sand it down some, in order to get the regulation spot-on. Which is why I was asking whether the felt is 'workable'..4mm , then hammered, is pretty thin already...
Interesting. Would this be readily available to a guy like me ?Abstract cloth is felt that is woven not pressed.
I use it in piano repair.
It's way tougher and stabile that regular felt.
Comes in different thickness/colors and density.
It's meant to withstand abrasion and compression.
All correct in my book.So, thinking in principles, I see the parameters of (1) noise reduction, and (2) firmness of transmission of motion between links. Both areas need appropriate material to reduce noise. As to transmission of motion, there is none at the key feet, so no issue there. But should the padding at the "back bar" be as firm as possible (while still quiet) or should it be less firm? If so, why? Thanks.
The woven felt is hard to sand down but there are many other high quality felts used in piano work.True...although I regularly use .4mm sheet cork as a regulating material and at times actually sand it down some, in order to get the regulation spot-on.
