Okay so I could search the net for hours but there is a huge amount of wisdom on here so I hope no one minds me tapping into it
I'm engaged in a project restoring a horn, my first and I will make many mistakes and perhaps a repair tech could do it in half the time, but I need a project at the moment for a variety of reasons.
Right the slides are stuck, obviously that's my job one. So I made a slide puller similar the one GijsVis was talkins about the other day. that didn't work so following my repair tech's procedure from another horn he did for me I de soldered and presrved the U shaped bit of slide so I could work on each arm indiviually. Got one free the other one is proving more difficult. It may be that after a couple more tricks are tried that I have to use brute force and a bit of ignorance to get the tube out and then make a new "arm" for the slide.
So to the question (finally) Do I need anything other than the brass tubing I can get from any soft metal merchant locally (obviously getting a match for size and thickness) or is there some special Brass that I need (obviously solder etc.)
Oh and I paid next to nothing for the horn and got a Mouthpiece I liked the look of into the deal so I'm not loosing much even If I stuff it up totaly
