Allan, As Andrew suggested, getting all the strings of a unison in the same plane is the primary goal. After that, mate the hammers to the strings. As far as uniformity from note to note, I wouldn't be overly concerned. Some pianos allow for more than others in this regard, but then there is the question of what your standard is - i.e. what are you making the strings level with? The floor? The keybed? The sloping Capo bar? The gravitational pull of the earth? Again, I'd focus on strings of the unison in the same plane, with the least amount of lifting necessary. I don't think you gain anything by being heavily focused on a "whole piano" string level. However, over-aggressive string lifting will cause you termination issues at the agraffe. William R.
