  Hi David


    I get an name error on the HWspec column.  Seems like the cupspline name is not recognized. When I open the spreadsheet a warning about macros being disabled comes on because the security level is set high and none of the macros are digitally signed. Any clues as to why ?

    Looks kinda cute tho for generating non-Stanwood standard Strikeweight curves.  I use a different approach based on a Bezier function that Mark Davidson helped me work out. Combined with the ratios of the three levers, the whippen radius weight and your desired BW, you get a bezier curve generated set of hammer radius weights and key radius weight.  I like very much the graph style that Rons has tho.

    In anycase... heres my sheet for anyone that may find it useful.  Again, I credit Mark Davidson for helping me figure out how to apply the Bezier function to the spreadsheet.

      Dear List,

      Ron Nossaman posted an excel spreadsheet a while back for graphing hammer 
      weights and I promised to make it available with my own edits and 
      additions.  My version contains two sheets. One for hammer weights (strike 
      weights minus 1.8g) and one for strike weights along with data columns for 
      all the curve standards. It's available at:

      http://www.stanwoodpiano.com/E-SmartChart2.3.xls

      It's virus free.   Comments and suggestions welcome.

      Hope this helps..

      Thanks Ron,

      David Stanwood
