 The Oboe BBoard

Question obviously directed at expert, or at least experienced, repairers....
On my student model wood oboe, the keyed F was terribly sharp, so I put in some heated-glue-gun stuff to close the top of the hole. Not a problem, except the cooling glue does not behave so well and I have to cut it a bit with a very sharp X-Acto (or Olfa) style knife.
Now, if I happen to scratch or nick the lip of the tone hole, that's disastrous to sealing!
Is there a home-made solution to even the lip.... say, sand paper on a rigid metal stick or using a ball reamer in a Dremmel tool?
Any idea how much a cork or "white" pad can compensate for unevenness?
Thanks

See the clarinet board for my reply http://test.woodwind.org/clarinet/BBoard/read.html?f=1&i=346663&t=346663.
As for pads, cork pad will only seat against a perfectly flat and chip-free tonehole and won't compensate for any unevenness. Skin and leather pads are more forgiving depending on how soft they are, but again they should only seat against the bedplace instead of smothering it with a deep impression.

Robin -
I would use a smooth, warm metal spatula to scrape around the hot glue and free the pad ring on the tone hole. DON'T use a Dremel tool! They are exceedingly hard to control and will chew off one side of the tone hole before you know what happened. You have pointed out the danger of using a knife, as well.
You might check out some solvents on your glue stick. I just tried acetone and it doesn't work, but also check in a paint store. Maybe a product like 'Goof-Off' will loosen it.
Worse case, use a flat, sharpened wooden spatula to scrape glue you have warmed to soften it. Anything harder than the tone hole risks damaging it.
Don't scrape across the pad seating ring. Even a wooden spatula can nick the sharp edge.
Try using a hair dryer to soften the glue and wipe it out with a Q-tip ir twisted paper towel.
Slow, patient, careful and next time use fingernail polish...
