back action replacement questions

[Gene Nelson]

Sorry about my terminology error - change "mounting blocks" (written below in error) to "damper tray to pivot blocks" from the belly rail gap.

  List,
  Replacing a back action with new Renner parts on 1918 SS-M. 
  Curious if red oak would do well as replacement mounting blocks for the damper tray rather than maple? (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.
  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. 
  When is a Steinway not a Steinway? When it is rebuilt in _oland.

  Regards,
  Gene Nelson
