> SW is strike weight, the weight of the hammer and shank as a horizontal
lever, supported at the center pin, weighed at the center line of the
hammer molding.  Sometimes this means the SW of a single hammer, sometimes
the overall SW of the full set.

digest Bill Spurlock's article (Grand Action Touchweight) on his web site
first.
