' lots of phone bidnuss and paperwork, today, but I DID get to strip the lacquer off of the CUSTOMER Holton 345 valveset and chemically clean it.
The picture (bad lighting - it's 7:40 P.M., now) shows the valveset to be in pretty good shape, but alignment is atrocious, and there are dented tubing knuckles, dented slide tubes, dented slide bows, and (as shown earlier) one replaced slide bow (crack was repairable, but the cracked slide bow just happened to be identical to one of the Miraphone slide bows for one of their instruments, so I bought a new one from them).
At least, though, it's READY for me to do "whatever" to it, because burning old lacquer (HAD I begun working on this WITHOUT first stripping off the lacquer) means that it will NO LONGER chemically strip...so I didn't want to un-solder NOR re-soldering anything on this prior to stripping off all the lacquer.
I have NOT stripped the slides themselves...I'll do that tomorrow, whilst going to town with the calipers on the "frame" (shown below).
The idea is NOT to take apart EVERYTHING and put it all back together "right".
The goal is to take apart AS LITTLE AS REQUIRED, to make it "right".
Whatever needs to be done, it needs to be done in the LEAST INVASIVE way possible (so as to have little-to-no effect on other segments of the valveset, so a lot of on-the-fly thinking - regarding various tacks to address various flaws (once problems have been identified and analyzed) - will be occurring.
To be even more clear: SUPERB RESULTS are the goal, and NOT "following some pre-dictated and drawn-out set of procedures"...
...ie. marvelous results resulting from as little toiling as possible - via continual "what's the least that can be done to make this as good as it can possibly be?" thinking and doing. That having been said, not hesitating to do absolutely as much as is required for those results.
What canNOT be seen in this straight-on picture are a set of (in my opinion...and surely would have been in the opinion of Holton factory model 345 assemblers) absurdly-long braces, which extend back to the body. (Could this tuba fit into ANY bag or case, with the valveset hanging off the front if this instrument that far...??) so - besides INTERNAL alignment - another goal is VALVESET-TO-BODY alignment. I'm not necessarily going to attempt to "nestle" this valveset down into the bows as deeply as possible, but (well...) just put the thing together as a " bone stock" 345 SHOULD be put together.
I'm not a "re-manufacturer". Rather, I'm a "put-it-back-as-much-like-it-was-er".
If (??) I can manage to slick it out so as many have no idea that something was ever distressed (yet WITHOUT pulling out the dreaded file and the dreaded belt sander), well... That's the ultimate goal, isn't it?
@the elephant Wade seems (??) to be interested in this, so I just tagged him. (I'm not really sure why, because he's as good at this stuff as anyone...??)
