I'd use 1000 emery cloth, very lightly and just enough to shine it up a bit. Instead, use the finest Scotchbrite pads if you want to go that way. Steel wools is really only good for rubbing on iron/steel or harder surfaces. Some of the steel fibers will embed themselve into the brass, defying any subsequent cleaning. Clean everything up carefully- get every last bit of steel wool and leftover sandpaper grit and dirt out of your slides and lubricate.Ĭhuck, I wouldn't use steel wool. Get some 000 steel wool and polish the slides-this stuff is too fine to scratch or remove material, but it will burnish out some of the unevenness. Further, I am of the opinion that a good tech is cheaper in the long run than ones who are more known for their low prices than their excellence.Ĭhuck(G) wrote:Here's a suggestion that might at least ameliorate the damage-at worst, it won't harm anything. I'm sure that I will be happier than if I had bought a $450 to $500 tuba instead. Regarding that $350 Eb tuba I described in another thread: I am probably going to spend perhaps $100 to $150 on it. I compare these costs with what it's worth for me. I don't compare repair or modification costs with what a horn costs.
If your tuba was cheap, or even free, spending less than $100 so that it is just the way you like it is more than worth while. I have mixed lighter and heavier lubricants for this slide until it moves with just the amount of resistance that I like. Also, without being asked, he put some bumpers (rubber O rings) to prevent a clacking sound when the slide is pushed all the way in, and put on a light cord to prevent the slide from coming out (without undoing the cord). Jim lapped the slide (it was already in good alignment) and vented the valve. My solution was to take the horn to one of the top brass repair techs in the Boston area and ask him to make it work better, and also to vent the first valve. Initially, the first valve slide was too hard to move easily. The only slide that I need to adjust while playing my five rotary valve CC tuba is the first valve slide.
