Hello!
So here's a piston from one of my horns. How do you repair these "built-in" valve guide?

Worn valve guides (not screwed, not on top)

No, but it's the one that keeps me from playing.

What kind of tuba is it?
Typically, these are small metal pieces that screw into the sides. You can buy some small plastic screws that have the same thread size and cut them down to the right size to use... I forget what size that is, but someone will chime in about that.
Besides being worn out and the valve spinning and not staying aligned, the new guides will be plastic and QUIET.

It's an old old old Besson & Co Eb Helicon.
I'll look closely if it is, in fact, screwed there.

Is that a little solder I see? it might just be a filed-to-fit piece of brass soldered into place.

So I messed with it.
Success so far.
I did a small plop of solder there and filed it down to size. Been playing a couple hours without problems!

Instead of talking to your plants, if you yelled at them would they still grow, but only to be troubled and insecure?

Re: Worn valve guides (not screwed, not on top)
Some people do a short-term fix soldering steel or brass guides in place if the threads are worn or stripped and they won't quit rotating. In the long term, if a replacement guide won't stay in place, it may have to be professionally repaired.
