Good luck with this one. Valves are expensive, even for King horns, where there is still a good supply. They are REALLY tough to find for other makes. I am surprised that no one has yet found it profitable to make valves and valve sets reasonably affordable and to order.

I think the reason for there not being a maker of "affordable" valve sets is that they are not cheap and easy to make. You need a lot of expensive machinery to do what is really high precision engineering. Anybody with say fifty grand to throw around might get the basic set up. Then comes making the milling jigs to put all the holes in the right places on all different sizes of valves and casings and on it goes. By the time one finished setting up you'd probably want to make about a hundred or more of 1 spec at about a grand each just to cover your set up costs.

Dan O could probably give a better idea and it might be even scarier!!!

That's the tough part, though I guess if you had the tooling and such for making the valves, the dies for the knuckles, the tubing, and all the other equipment (such as plating...) you may as well just build instruments.

I wouldn't mind finding a .687-.689 front action valveset with all slides and crooks for my little Eb (maybe F, Maybe D-CC) project...
