Alto Trombone

Playable Eb Alto Trombone. Based on a King 3B tenor trombone shrunken down 30 percent. It doesn't sound great but at least it can play in tune.

Fuse parts together with acetone or super glue (make sure it is air tight). To align parts, use a flat surface and roll the tubes as they fuse to force perfect straightness. Sand the inner slide after fusing so it moves easily inside the outer slide (a little grease with help).

The screw, nut, and tapered connector parts may require some cleanup to work together smoothly. I suggest verifying they are fitting before fusing to the other parts.

I did not include a mouthpiece. It uses a normal tenor trombone mouthpiece (There are several on this site already).
