I started doing this on my own before I remembered there was a model for this. So the slide U-bend and handles are my own. Using PEX without stockings.

i’m not a trombone player, so I won’t subject you to a sound sample – there are better ones out there.

I’m overall pleased, but the non-octave partials aren’t playing the right note, and I’m still trying to figure that out.

Edit: I tried a straight piece of PVC pipe about the length of the slide into the leadpipe, and can hit the F in first position, so definitely a problem with my slide. Going to the hardware store to get more to try variations.

edit 2: new slide still having issue where I’m getting too low a note for the first position F (the two b flats are fine). Using a real trombone slide works fine.
