Hope,the turkey tasted great!</DIV> <DIV>Leveling leads on back checks can be problematic. On some older pianos there are clear marks from old-fashioned key leveling leads which had 2 sharp nails and were tapped with light hammer near the capstan,but,probably,it was too time consuming.I do have a sozen of those leads with nails and they work.</DIV> <DIV>But about 20 years ago late Roger WEisensteiner introduced KImball factory method:about 15" machine bolt is filled through it's lenght with flat machine washers  1 1/2" outside dia 3/4" inside hole,about 100 of them fill     entire length of the bolt.Placed over an octave  this method enbles to do key leveling fast ,especially on verticals ,when the action is out.I had good experience doing it that way and have one of those units in the shop and one for the field work. {I'm sure my friend JOe Garrett can give a better description of that method,but I had shown it in my classes and a few local technicians copied that method.  Best Regards to you all.
