It might take a while to get the feel but = you could do it. Same with dip, just takes practice which will yield pretty = accurate results. Your method would probably work but I haven't tried it.</SPAN></FONT></DIV> <DIV><FONT face=Arial color=#0000ff size=2><SPAN = class=110460606-21112001>As to the glides, I don't change them because it will affect the leveling. You = have a good point about the wear factor but it has not caused me a problem yet. I still have to do some fine leveling in the piano. By = the way, Harbor Freight sells a small folding stool on wheels that puts me = about the right height for key leveling and damper work on grands.

The compression of the felt would concern me.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>How do you like this?  Suppose = instead of setting dip you measure the distance from the top of the key (natural) = to the key bed and then the top of the key frame to the key bed.  You = could use any type of depth gauge like a dial caliper or just a good = rule.</FONT></DIV> <DIV><FONT face=Arial size=2>This would be related to dip but would = be more accurate and the key height would refer to the back rail of the key = frame and the balance rail position  and the frame height would check = the front rail.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>I still think that after the glide = bolts have been set in the piano, they should be backed out a set amount (like 1/2 turn) = to prevent an error due to wear of the glide dowels.  They then can be = accurately reset before reinstalling the action.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Regards</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Carl Meyer  Assoc.
