Does anyone have a Edwards/Getzen bass trombone tuning slide and some calipers laying around?  I need to measure the taper...inside diameter at the very and and again 1/2 inside.

I'm making a tool to expand them to fit properly

Thx

I found one .02" per 1/2 inch...made a tapered die to go in my expander...
