King valve section/Conn 88H bell section
(1/1)
britvalver:
Could a King 2B valve section be used with a Conn 88H bell section, to give a King/Conn hybrid valve trombone? Are the 2 sections compatible size-wise?
dj kennedy:
bore  size  of  king  is 485
88h  547
==========
conn  receiver  is  larger diameter
=======
the  90g   marching  trombone uses  an  8h bell  coupled  w  valve section
it has  a  larger  bore  than  485
=============
88h//2bv --there  is  a pretty  large  gap//step in bores 
=====
sould suggest  a  king  cleveland  or  605  //hn  white  tempo  bell 
instead  of  88 h  bell

You're trying to replicate my favorite horn--the Conn 90G large bore valve trombone. It uses a baritone valve section with around a .550 bore. To make one with a traditional wrap, you'd need to start with a much larger valve section. The ones from DEG or Bach marching baritones work quite nicely, but need some major modification to make them work. I don't think there's any way you'll get your King 2B valve section to play well with an 88H bell section. As DJ pointed out, the jump in bore is too great.
