Every
Johannes Gerber saxophone
mouthpiece starts out as a solid round or hexagonal bar of very
high quality brass or bronze.
First, the shank is cut on a manual lathe, then the facing is
rough cut on a machine Johannes
designed and built. The facing machine takes time to set up, therefore
5 to 10 blanks are normally produced simultaneously up to this
point.
|
|
|
Next
the body is shaped in a special fixture. After that, the beak
is shaped on a special machine. With the facing roughly created,
the rails and window are marked out by hand. Next the chamber
is machined on a manual milling machine to closely match the markings.
Now the bore is drilled precisely on a lathe.
|
|
| With
the basic blank finished, the tedious hand finishing starts. First,
the table and facing are smoothed and adjusted to very close tolerances
to match the specifications. Now the tip area is shaped to fit 3
different reed brands as closely as possible. The throat area is
cut and smoothed with a high speed flexible shaft machine (by hand).
Next, the baffle is cut down by filing to a desirable height - this
step brings the tip opening to 98% of its final measurement. Play
testing begins here. |
|
| Now
the cleaning starts, with different grits of carbide paper wrapped
around files, and silicon impregnated disks, the inside of the chamber
is polished until all marks are gone. The biteplate is cut from
a sheet and glued into the pocket. Now the biteplate gets filed
down until it perfectly matches the beak. While the mouthpiece is
held in a special fixture, the whole body gets sanded with strips
of carbide paper until 1200 grit, all by hand, very carefully not
to touch the perfect facing and rails - until every scratch mark
is removed. |
|
| The
inside gets polished with a liquid abrasive and woolen buff on a
flex shaft machine. Utmost care is taken not to touch the fine tip
rail and facing, only achievable by a very steady hand. Once the
inside is shining, the outside is polished with a jewelry buffing
machine. At this stage surgical gloves are worn not to contaminate
the brass with oils from bare hands. When meticulously polished,
the mouthpiece is engraved by hand and then washed in a warm soap
bath. |
|
|
Finally,
the mouthpiece is washed in several degreasing and cleaning solutions
before gold plated in a hardened 24K gold solution, which is very
hard wearing.
|
|
|
At
this moment the above processes take approximately 5 working days
per mouthpiece. It takes an additional 1 day to make the ligature,
which is also completely handmade from bronze.
When
everything is completed, the mouthpiece and ligature is packed
into a very attractive satin-finished tin and mailed.
