Step 5Making the holds
I don't know if I named them right but the pieces of wood, I called them holds, are there to keep the tube parallel and to have grip on the trombone.
First measure the distance between the middle of tubes of the 3/4" tube piece and sign this on one of the wood pieces. On these points you drill a hole with a 3/4" speed drill. Don't drill right away trough it but when the point of the drill is on the other side, turn around the wood and drill from the other side. This way you won't have any splinters on the edges.
Put the hold on the tubes.
Do the same with the thinner tube but make the hold twice. One to keep the bended tubes parallel and one to put the straight end the bended one together.
