TubeNet

When I was in college, I spent a few summers repairing instruments in a quasi-training repair shop, I remember us having some fun with this tool (and similar tools) on spare and junk parts when we got bored....

Thats a great way to kill time (and parts!)

I'm very much in agreement that slide expanders can totally ruin tuning slides and trombone slides if they are mis-used. The problem with most expanders is that only the very end of the expander is wedged outward and therefore, only the tip of the expander contacts the tube. There were some expanders made that work very well because they are shaped in a way that the part of the expander that actually contacts the tube is a bulge that is in the center of the business end. When I do find cause to use this tool, it is done very carefully and NEVER with a twising motion. The tool is made to use axially... NOT radially.

I think the only good way to fix a dent in a trombone slide is with the Ferree's trombone slide rollers and proper fitting mandrels. The BIG problem is... only a small percentage of trombone players actually know how to take care of their slide and by the time I see the slides, lots of them are in very poor condition. School-owned and student trombones.... bleeeech!

trombone tools o' destruction

I thought those were called "trombonists"
