I'm glad you seem to be adequately adept to use these things, Terry, and I say that without a molecule of sarcasm. Considering your well-noted dedication to quality, I am sure that you speak truthfully. But I have seen SO MANY sets of hammers gruesomely mutilated by "tooners" with these motorized Implements of Doom that I would not advise anyone to use them: even if I could myself! My favorite implement of hammer filing is a spring-steel machinist's rule with self-stick sandpaper ( available from auto paint stores in various grades ) on it. It is more reliably flat than the wooden paddles, THINNER ( to get under and around stuff ) lighter and narrower than the Pianotech "permanent" sanding paddle ( which is also nice, but harder for me to control ) and can even be washed out afterwards, if you use the right paper. ( Last stuff I used was some green 3M stuff. The dye washed out, but the paper stuck and lasted for about 10 filings! ) Thump --- Joe And Penny Goss <imatunr@srvinet.com> wrote: > Hi David, > That is exactly the same experience that I had. > Tried all of the motorized > ways after first finding that the paddle made my > elbows flare up.
