Hi Ric & List, I have just spent half an hour playing around with my 3 note model having been thinking about this half punching thing on and off all day. What a saddo! My final experiment was to discard the punching and put a cente pin behind the balance pin. A 26 gauge kept the key level integrity. I couldn't believe how easily the hammer flew with the same weighting in the key. I have just come to my PC and see that RicB has already tried this as an experiment. I'm reasonably new to all this geometry business and find these relevations fascinating. One question would be, how does this change of the fulcrum with the resultant loss of 'magic line' integrity, manifest itself in feel to a pianist. Does this method of lightening DW result in an uncontrolable feel? ric -------------- next part -------------- An HTML attachment was scrubbed...
