Task: refurbish a little, level keys, regulate. Let off screws frozen pretty solid. What is the cheapest, quickest, most appropriate fix for this so that I can regulate the darn thing? Remove rails and toast each screw with a torch? Lubricate with liquid wrench or something else? Replace rail? Are universal replacements available, or, I would imagine, that the spacing will be different on any given piano? Going for the quick fix here. Low budget, make it work. </BLOCKQUOTE> For the cheapest, easiest fix, I would try the liquid wrench. If that doesn't' work, don't bother with the let off, unless the hammers are blocking against the strings. Then try lowering the entire rail by bending the brackets. Otherwise, do onto (that one) as you would have them do onto others. Wim </HTML>
