[CAUT] Shank to Hammer weight spreadsheet

[Ed Sutton]

I weigh the shanks on the Stanwood strikeweight rig, as levers, not dead weight.  
The hammer heads are weighed "dead weight" on the gram scale, separate from the shanks.
(Also, I prepare all 90 or 92 hammers in the package, so I have some extra hammers to choose from in the 90 degree bore angle section.)
 I don't know which method is faster. I like playing with my computer, and I like drilling and gluing wood, so it doesn't matter that much to me. I might do it another way next time.

Meanwhile, I just read that in the Grotrian factory they sort to put the low-pitched shanks at the top. Better for the tone that way. It was in print, so it must be true.

  My question is, if you are weighing the whole shank and flange, how do you know the distribution of the difference in weight? If 90% of the weight difference is from the knuckle through the flange, the SW wouldn't change much and so the presumed evening out of the weights is not there. The distribution of the mass could vary from shank to shank at all the different weights.

  I like the idea of listening to the sound of the shanks. A thinner light shank should produce a higher sound. Very quick too.

    I don't think you get the idea. Mating a shank's SW with a
    hammer weight will require less hammer mass alteration
    to achieve a smooth SW curve.
