Valve Guide Installation

The Valve Guide on my 119 year old Besson Eb just came off. It origionally had a metal one but years before I bought it, it came off somehow so I SUPER GLUED a plastic one on top. It worked great and smoothly for a year or maybe two. I plan on just installing it on the top of the piston like I did before but was considering using JB Weld instead of superglue. Would JB Weld be safe to use?

What you need can probably be made in the shop or can be ordered and altered to fit from a generic or universal guide. This is not hard to do if you have the experience, the tooling and the parts at hand. It will not cost you lots of money. If you value this horn get it fixed properly.

Good luck.

The piece is made. It is a matter of installing it.

Did you use a copper or brass nail? I'd be concerned about wear to the valve guide slot with any harder material.

Consider the source! It was probably on his Bass Trombone!
