bottom bow and bell are not soldered.
They need to be sight-aligned about fifteen or twenty times, before I've convinced myself that they are just where they belong.
I'm not fixing that little crack until I'm convinced that I'm completely done messing with the bell.
The bell rim had one bent-inward (not up/down, but - again - INWARD) spot, which I fixed with a regular-ol' claw hammer...
WHAM !!! (yes, really).
All of the Holton 345 bottom bows I've dealt with have been (curvature-wise) "in a hurry" - on the small side (just about identical).
Were that addressed (for the sake of looks...??) something else would surely need to be shortened - to compensate.
We tend to like "pretty/symmetrical", but I doubt that acoustics and playing characteristics much care.
@the elephant I forgot my mandrel...
(Did you play your gig, yet, and did you use the Holton?)
also...
Several years ago, I did some repair work on a FACTORY CC-345 for a retired guy (with a bad ticker) down near Baton Rogue named Clark W. Giffin.
Per typical, when he had it straightened out (decades ago) and re-lacquered, the dolts at the "overhaul shop" (did he tell me: "in Texas"...??) tossed the bottom bow cap in the trash (just as was done with this one that I'm currently working to bring back to as-good-as-can-be...I hate "restore" just about as much as I hate "tweak").
Otherwise, though, it was a factory C. I heard that he passed. I wonder where that tuba ended up? (I have no jones for it, just fwiw...I've never been able to get the "
WHUMP!"
out of a CC-345 that I can coax from a really good BB-345.)
