Removing tubing sleeve

[roweenie]

Is there an effective way of removing a bore spacer inner sleeve with the tubing installed on the horn? The only experience I have is driving it out with heat and penetrating oil when the tube is off the horn.

Maybe some sort of special tool for that purpose?

Got it figured out.

I used a lot of penetrating oil and an adjustable reamer:



I expanded the reamer inside the sleeve so it would grip, and just turned until it freed up.

Not a traditional use for the tool, but it worked quite well!

You did a lot more work than I had to do. I was cleaning the main tuning slide tube of my Wessex Helicon with some paper towel and the inner tubing sleeve just came out. Bounty, the quicker taker outer.

Lucky you

This tubing is probably over 50 years old. What happens is it gets corroded in place, and can be a real bugger to dislodge. On a new horn it should be easy, but not THAT easy......



(As a younger man I used to go to Rosie's Diner in Little Ferry, NJ - never saw her there, BTW.... )

Some of those 'filler tubes' can be a real pain to get out.... especially is a spot of solder has somehow gotten inside. I'll look into your approach next time I'm faced with the problem. Sounds like a good plan. I often used another inner tube of the same size to drive the insert out but once anything get swelled... you're pretty much done.

Dan, if the tube was off the horn, I would have done it exactly the way you described (drive it out with heat and another tube). The only reason I used the reamer was because the tube was still on the horn and I was too lazy to take it off....

I expanded it just enough to "bite", yet not actually "expand".
