Soon after I'd had my trumpet cleaned and lacquered I found the crook on the main tuning slide hadn't been soldered. Rather than having to solder it and then re lacquer it I glued it in place with an engineering grade epoxy. It worked ok and the trumpet plays just as well as before, that's to say very well. If it ever needs undoing it will be a problem for the tech guy unless they know how to dissolve engineering grade epoxy. Does anyone happen to know about this subject?

WHY would you do that??? It could have been soldered correctly, then spot re-lacquered, and who cleaned and re-lacquered it without noticing the slide was not soldered?

I would find a qualified tech and have it fixed, though at this point you may have to replace the slide..... which is not that big of a deal.

We run across well meaning customers that do short term fixes which then become more complicated than if brought in to begin with. Consiquently you'll end up paying extra to remove the epoxy before it can be soldered properly.

Ah, you're not the first person to do this! It was the summer of '77 and the 3rd valve slide of my trusty Selmer radial 99 came apart.

Back then, it was about a 2 hour train ride to the closest known repair place, and a phone call told me it wold take a month to get the repair done. The price was weeks of allowance. (Never get between a kid and his allowance!)

So I cleaned and prepared the two solder points, and used a 2 part epoxy glue to create the bond, and set the parts using the trumpet as a jig. The slide moved freely, so I walked off for 24 hours... it worked a charm.

A couple of years later, I took it to this repair place, and got the 1st valve trigger changed to a saddle and a fixed ring put on the 3rd. And asked for the slide to be resoldered.

They did the first 2 bits but told me the epoxy looked like it would never fail and the alignment was perfect, so leave it alone!

It's still there...

Now the home repair jobs that come into my studio from well meaning parents, kids and next door neighbours? The lesson here is that one example of sheer blind luck is not the rule!

cheers

Andy

Ok, I’ll back pedal a bit here. If someone has no access to a tech, or if their only horn might be tied up in a repair shop for weeks, a DIY fix like glue might seem like a reasonable option, but I would certainly do anything I could think of before I would try that.

I love it when the torch hits a glue joint - lots of toxic fumes and perhaps flames!
