I have seen the how it's made on trumpets and it really does not look that hard to do but rather takes practice to get it right (kind of like playing the trumpet). After seeing Brekelefuw and his tuning slide I was curios if I could do that... Although I do not have any equipment, nor any experience with metal working I thought it would be a cool project to take on. I do understand that one does not simply make a tuning slide but, a little guide on how to do it would be helpful in my quest. I hope to one day build my own horn but obviously should start with something basic like the slide. Some things that would be greatly appreciated are- - List of materials - step by step guide - And a few pictures if you have any on hand I am also willing to make some of my own machinery if possible. Also since I previously mentioned I do not have any metal working experience, specifics will help.
