Do be careful with the synthetic reducer "squirt". Though synthetic reducers can be made of any number of solvents, the one recommended for PDF is pure xylene. Not something you want to be inhaling or washing your hands with.

I tried it today, and I really like how it works. The bushing seems to provide additional PDF to the pinblock as the pin is driven through. One question, though: when the bushings have the right liquid content, you get a little bit of squirt as they're driven. So I had to wipe down the plate with a solvent-moistened cloth after driving each bushing. Is this how it works for you? Any time-saving tricks for the clean-up? thanks, Mike ----- Original Message ----- From: Joseph Garrett <joegarrett@earthlink.net> To: <pianotech@ptg.org> Sent: Tuesday, May 28, 2002 10:16 PM Subject: Oversize pins in a doped block/Mike spalding's ? re.bushings > Mike, > The beauty of soaking the bushings is that the bushing becomes flexible! > Here's how it's done: Several days to a week before stinging starts, put the > correct size/number of bushings in a large jar.
