Vacuum question

[Dave Bagwill]

Maybe I'll try it on one of my student's instruments, then blame Ken's kit if it all implodes!! That is a stroke of genius!! :-)

I believe I will experiment a little when I find the time, though. It seems like an excellent way to get constant pressure right on the rim where it belongs.

The real question that needs to be answered and explained in all of this is.....................

"if a tree falls in the forest, and no one is there to hear it, did it make a sound?"
Can your fancy smancy Super Computer answer that one Dave?

Kevin (I know, I'm just full of it today :>))

[Dave Bagwill]

Yes Kevin, it can answer that question. :-)

If you support the rim around the perimeter on the bottom (back or sound-board) and fabricate a standoff so the pressure is applied to the rim and blocks only your idea will work. There are gluing systems that use an inflatable rubber bladder to apply pressure to the perimeter -- same as your idea only a different pressure source --- My $.02, seems like a lot of trouble? What Would you hope to gain?

[Dave Bagwill]

No trouble to speak of, really. Don't know as I would gain anything by it, either, but then again....maybe I would.
For me it may be worth a try on a non-important rim sometime.
