Slide trimming

Post by MikeMason »

Is there an acceptable way to cut a slide without removing the tube from the horn? Dremel tool? I need my 2j 3rd slide to be an inch or 2 shorter.

I use a counter bore tool with a pilot slightly smaller than the ID of the tubing. Very quick and clean. A VERY light deburring of the ID and OD and you're done. I can take off 1/2" in fifteen seconds with no risk of cutting into anything else.

Bloke posted some very good advice on just this subject. I recommend asking him to read it before he cuts anything.

Thanks! Forwarding to him now. The fifth valve has really made the horn fun to play, just 2+3 combinations too flat.

Can you post a picture of the horn? I'm curious to see how the 5th valve was laid out.
