Besides all the typical stuff, I had to remove the vertical play from the rotor to make it stop clicking and then I had to replace the links on the rotor linkage which were ridiculously rattly, as they were OEM and little pieces of crap. To complicate things I think they were 2.6 mm threaded and all I have here is 3 mm thread the small size. Because he was going to owe me so much money for all the time, I found him too quiet Chinese links and replaced his originals with those along with a piece of 3 mm all thread that I curved a little bit and added some knurled lock rings...
...but the playing slide crook was all smushed flat, both of the outside slide tubes have been repaired by some hack with a slide expander, and I had to make them work anyway, because it's for a 7th grader, and it's really too early to be replacing slide tubes for somebody who's likely to damage them again anyway... And it's hard to take parts ruined by tools and make them usable again. Also, since I slide rebuild was not justified due to the condition of the outside tubes, I was doing a hillbilly repair with my hands, and had to keep rechecking it because the tubes continue to want to flex back to where they had been before. I finally got them to stay put in a enough of a parallel and co-planar position so as the slide actually feels what I would rate as "pretty good"... Which is probably one notch below "good", which is two or three notches below "bloke good" (which - hopefully - is better than new)...ie.
(etc.)Wow. That's a happenin' slide, man!
There were other typical things like bell dents and creases and taking serious dents out of that elongated F attachment slide on that model - which I managed to do without taking that slide apart, even though it's dicey (as that slide is delicate). My work-around was to solder a piece of crap across the slide tubes to prevent the F-attachment slide bow from folding - while I slung dent balls through it.
Even the slide lock was giving me problems, balancing having it not click against the end ring versus catching the lock itself. Someone else had tried to solve the problem by adding extra felt rings in the cork barrels, so I had to dig those out.
As far as the thumb linkage was concerned, someone had soldered the saddle for the lever itself on crooked whereby its hinge screw would not screw in, so they simply cut the threads off of the hinge screw and the thumb trigger was just floating off of one side.
... So I had to straighten out the saddle, get it all lined up collinearly and also remove lateral play and then make a screw for it because I didn't have that screw in stock... All I could find in my Vincent Bach drawer were the water key screws and the thumb saddle screw for the old style thumb saddle which was a slightly smaller diameter hinge screw. (I had to scrounge all through Mrs bloke's woodwind stuff to find a .110" diameter junk screw, and then run its threads down to a 2-56 thread size for the trombone thumb saddle... They playing slide receiver was also cocked off with the wrong angle, and actually the correct way to straighten it is not to unsolder it and reposition it but to bend it back to where it was, which requires particular care, since it is soldered directly to one of the rotor knuckles. What a bunch of jazz to have to mess with... And having to be polite the whole time... 
Something else it's a little bit awkward about spending so many hours on someone's instrument is having to charge them so much money for all that work, but everyone seems to be really happy with their instruments and to pay cheerfully, so that helps make it not so difficult.
I just ate two pieces of store brand bologna and a slice of cheese and drank a cup of coffee here - finally - at 4:20 p.m.
I think I'm going to lay down for a little bit, try to not think about anything, and then maybe go back out there tonight and work on those crappy (yet way less crappy than they were when I started working on them) King fiberglass sousaphones that I meant to be working on today, because those need to disappear back to the school that owns them and turn into money. Hey: Three of the four are nearly done.
