Thanks J, that is very helpful/useful info for some boardmembers.
I would reccomend one small change in application however.
Using a hole punch would provide a much too large of a hole for the grip screw on a R9. The screw would actually fall through the hole.
You will probalbly have to cut out your own tiny circle that would fit into the grip hole and then use a small drill bit (1/64) or a nail/safety pin to punch a hole into the rubber.
Of course trying to punch a hole that way would give one of those ragged "resealable" type of holes where you would have to moderately force the screw through the rubber.
This might actually work better than Locktite or nail polish.
Worth a try for those of us having a headache with loose grip screws.
Thanks J
