Michael, Q-Tips leave cotton residue. Don't know if that's relevant, but on the off-chance....????<G> Probably, doesn't matter one darned bit. I use spinet shanks because they fit through the plate bushing holes easily and there really isn't much else they're good for.<G> Joe Joe Garrett, R.P.T.

Not seeing this done, I can't picture to process. Al, If I am stringing a piano w/o plate bushings, it's pretty straight forward. Spinet hammer shank; dip in a plastic cup of PDF; let drip; swab the hole(s), (I usually swab one unison at a time); drive pin, (after pre-coiling wire on to it); set coil; finish driving to proper level. If I am doing a piano with plate bushings, I have all of the bushings in a solution of PDF, (10%) and synthetic reducer, (the thinner for my PDF), (90%). I let them soak over night so that they all become "water-logged" and sink in the solution. I take 2 unisons out of the solution and let them "dry" somewhat, on a paper towel, while I am premeasuring wire, etc. This keeps them from squirting all over the darned place. The reason for this proceedure is to make the bushing very pliable so that it won't get a permanent malformation. The T.P. squishes through it and doesn't split the bushing. Hope that helps. Joe Joe Garrett, R.P.T. (Oregon) Captain, Tool Police Squares R I Hi Joe, I know they aren't considered tools but q-tips work a lot better than a hammer shank, you have to replace them more frequently but they don't drip as much. On my last few restrings I just used a plain old oil based non-tinted varnish & swabbed the holes(no more than 2 at a time)using the afore mentioned q-tips. Like you I pre-soaked the bushings in the PDF as well, more for color than any other reason. Mike -- It is the mark of an educated mind to be able to entertain a thought without accepting it.
