Question about repositioning a leadpipe

Post by TheHatTuba »

For the repair techs out there, is it safe to bend a leadpipe a bit without filling it? I want the receiver bent out an inch or so and lowered, and the repair tech I took it to said they'd unsolder it from the bell and simply pull/bend it out. My main concern would be collapsing the leadpipe.

I agree with Joe. Unless the 'move' is very slight... the leadpipe needs to come off the horn. Then annealed. Then filled with pitch, lead, Cerrobend, etc. Bent and then prepped to be put back on the horn.

Leadpipes, especially on older horns are famous for cracking where the seams are. Also... anytime you bend a tube without filling it with material to support it from the inside, it's going to go out of round.

I used to spend a lot of time moving the leadpipes on my own horns (and I have a BUNCH!). I save much time now by utilizing a play stand to support my horns at the correct height.

+1. Cheaper and safer as well, assuming it solves whatever issue it is that's spurring the interest.
