It seems to me that a proper adjustment of the balance rail glide bolts would be the first thing I would look into. Then, I'd make sure that the Balance pin hole in the key is has no slop in it. Too many times I've seen over sized holes as some think it's OK to have the key so loose around the pin so you can lift the key at the front so it drops without any friction. That's OK if your traveling the key parallel to the frame but forcing up in an arc does not give proper measurements for rocker function. If easing is needed I always ream the hole side to side... not front to back. Why would the manufacture over weigh the keystick so much? If your touch can detect it than I would definitely look into the key bedding situation</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Some interesting answers on this subject!

The keys bounce after you let go and you can feel it in your fingers when playing. Nothing worked, including backrail cloth and it did have a ton of lead in the keys. Someone in my Chapter  suggested the wip cushions may be too hard, and they were. I turned the stack over and steamed them and it removed the dimples and softened them up. It did help noticeably but the problem is still there.<BR><BR>Mike<BR><BR><BR>Mike McCoy<BR><BR>Cy Shuster wrote: <BLOCKQUOTE cite=mid024101c6855f$39b0c030$6549a8c0@BUSTER type="cite"> <META content="MSHTML 6.00.2900.2873" name=GENERATOR> <STYLE></STYLE> <DIV><FONT size=2>Could new back rail cloth help prevent bounce?  I'm thinking that worn cloth would be like bouncing right off the wood, where new cloth would give more cushioning...</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>--Cy--</FONT></DIV> <DIV><FONT size=2><STRONG>shuster</STRONG>piano.com</FONT></DIV> <DIV> </DIV></BLOCKQUOTE></BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
