I just don't see how someone could work on tubas without some kind of lathe.
So far, I have used my little Sherline to make:
a few receivers;
several rims that thread onto the Helleberg cup that I also threaded;
lots of Delrin valve guides to fit my Nirschl (VMI, Perantucci) valves;
Delrin spacers to replace the cork under rubberized valve felts;
piston-valve springs with various stiffnesses;
new spindles for St. Petersburg valve rotors;
drilled rotor caps for setscrews for my Alexander F rotors;
bearings and shafts for a new machine (spatulas) for my Alex (rest of the machine was made using the milling column attachment);
tooling to hold mouthpieces, rotors, etc. for machining operations;
tapered reamers for adjusting moutpiece fit, etc.

Just think how much money you could save with one of these babies!

[Caveat: the Sherline is a well-made, although lightweight, lathe, and many operations require considerable thought to perform without exceeding the machine's limitations. If you have the space and the luck to find one at a reasonable price, a cast iron South Bend, Logan, Myford, Colchester, or Monarch (the York of lathes) will do a better job, faster and easier, but you can't shake those off and put them in a closet when you are done making chips like you can with the Sherline.]
