Chris & others,
there are two different ways cutting the bell:
1) during the production process of a new horn:
a) bell flare section is made of a flat disk, resulting in much stress
in the
material & some unwanted noise in higher dynamics
b) bell flare is cut from the still unbent full part after the valve
section.
in this process, the cutting can be done precisely at the desired
point,
so the screw ring can fit perfectly. Furthermore, bending this long
section is much easier.
2) cutting the bell on a given horn, old or new:
Quite delicate & difficult operation, which might alter some properties of
the horn
perhaps. Applying the screw ring to the horn is quite difficult. Without
dismantling
the horn, the trunk of the bell section has to be squeezed (losing
tension) so the
ring can be brought in place, the trunk has to be brought back to measures
to
fit the ring inside. There is also the problem of cutting the bell right
at the desired place.
Just have a look onto the horn & understand.
Remember, cutting a bell of a ready made horn, old or new, is problematic by
the
process itself & it could alter the playing properties in rare cases.
