(I am a long distance from a hardwood store) The existing was bad as one side was pine and egg shaped in the pin hole - the other side still original maple but suffering from the effects of the age and excess tray wobble.</FONT></DIV> <DIV><FONT face=Arial size=2>Also, how much friction on the lift lever flanges? The Renner parts are about 4.5 to 5 grams from the factory - they are a bit tight in my opinion - should I try for about 2 to 3 grams? I am curious because the 4.5 gram is consistant for the entire set with very slight variation. </FONT></DIV> <DIV><FONT face=Arial size=2>When is a Steinway not a Steinway?
