This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Thank you all for the fast responses to my question. I'll try a few of the suggestions and post the results here in a few weeks. The worst screws are the rep. spring adjustment screws. (This piano has the Aeolian grand type whippens with the rep spring that hooks into a cord at the back end.) The screw goes right through the repetition lever and are so tight now that turning them tends to torque the whole lever and the whippen at the flange centers & I sure don't want to do that. A soldering iron is probably my best bet here. I'll let you know.

I have just finished inspecting the action of an old Hallet & Davis baby grand. (The serial number seems to have been long ago obliterated but I'm guessing it's about 60-70 years old.) The piano was just "rebuilt" but the "rebuilder" didn't bother to regulate the action. This action isn't a little out, it's grossly out! Perhaps the reason it wasn't regulated is that most of the regulating screws are binding so badly I think they would break, or worse - strip the holes if they were turned any large amount. I will shortly be attempting to regulate this action. I'm looking for any experiences out there with techniques to free up binding regulating screws. It has been suggested that I try pin-point applications of Proteck's Prolube liquid, which I will. But I would like to have more than one card up my sleeve before I start this job. Can anyone suggest other approaches? I thought of Liquid Wrench, but would it harm the action? Thanks, Arnie Arnold D.
