1.
Removing all keywork from the instrument.
2. If
the instrument has a removable bell then it is removed from the body and the
joint checked to make sure it doesn't leak or hasn't been damaged.
3.
Rollers are removed, cleaned and replaced.
4. All
rods are spun on a lathe to test for straightness.
5.
Left-hand and right-hand pillar sections are checked for true alignment.
6. All
barrels are checked to make sure they aren't bent - if they are then they will
be straightened.
7.
Octave pipes are cleaned out.
8. Tone
holes cleaned.
9. Pads
cleaned if necessary.
10. Any
pads below standard - replace.
11. Any
cork or felt below standard - replace.
12. Any
pads that need reseating - reseat.
13. The
full instrument regulated.
14. The
full instrument oiled.
15.
Finallly the instrument is tested to the max with two different mouthpieces
with a classical and jazz embouchure. Usually at this point there are one or
two small adjustments to ensure it feels and blows correctly. My
interpretation of an instrument that has been correctly serviced is - it
should play as it did when it was new.
