popsicle stick engineering

[Clark Sprague]

Hi, All!  I have been dealing with a S&S B that I found with up to 9 leads in some of the low tenor keys.  All the parts had been replaced with Renner to get rid of the Teflon flanges, but it was heavy, sluggish, and just a chore to play for long.  I am not all that familiar with the Stanwood protocols, but as time goes on, the concept gets more and more attractive.  What I found, was that I had to shorten the dip, lengthen the blow, to get it less laborious to play.  So, what I suspect , is that the capstan placement is incorrect for the parts used, or was incorrect from the start?  They also had the damper timing late to try to make it feel lighter, so late that the hammer almost hit the strings before it lifted.
    Ric, your comments on the more creative combinations of blow, dip, etc hit a chord with me on this beast.
    There were too many leads in from the factory, and you could tell be looking that some more were added with the new parts, as they did not look factory at all,  so the problems just got worse, evidently with the parts replacement.

  Hi Kent, others.

  I'm glad you put this up Jon. I remember 6 years ago when you brought this idea to my attention off list. I still have all that exchange. Good stuff.  The idea of thinking about the whippen needing a <<required travel distance>> struck home a note back then.
