I'm looking for a rotary valve to use on my Eb tuba project as a 5th valve. The small side of the main tuning slide is 0.660 bore and the large side is about 0.710. If you have a rotor with either of these bore sizes, please let me know. If you have the smaller size, I should have tubing for it, if you have the larger size, I will need tubing as well if you have any, but I'd be happy just to start with a valve.
I have the old, top action, three valve section I removed from the Eb tuba I'm refurbishing if that interests you as a trade option. Thanks!

If at first you don't succeed, skydiving's probably not for you.

I've seen the elephant's posts about those and thought the same thing. The ports are slanted on those if I remember right, but if anyone had one I'd take it!

Re: 0.660 or 0.710 Bore Rotary Valve
My calipers are reading 0.695 ID on the ferrule I could use and 0.685 ID on the MTS now... I don't know where I got 0.660 from, unless I was measuring the inner slide for that. Either way, there you go. Thanks!

Re: 0.660 or 0.710 Bore Rotary Valve
Ok, then the measurements I gave you are correct. The small side of the main tuning slide was 0.685.

No worries.
I've posted some pictures for clarity below. If you have a rotary valve whose ports will fit *inside* either of these tubes, please let me know. Thanks!

Re: 0.660 or 0.710 Bore Rotary Valve
I was able to find one that will work on the large side of the tuning slide. Thanks folks!
