Ron et al, I like using Robertson screws to keep the little darlings, (jr. high & such), out of the insides of school pianos. For a while, there was a spate of vandalism, where many mid treble hammers were forcibly removed! According to the scuttlebutt around school, it was drummers. Go figger! A couple of well placed Robertson"s did the trick> Of course the next tuner was put at a disadvantage><g> Local Ace Hardware has the necessary drivers. Joe Joe Garrett, R.P.T.
