The NH Chapter's dream has come true. You may remember discussion of exploration to inner workings of deep and fast repetition using high-speed videography. The NH Chapter will get to film an afternoon's worth of the stuff on a machine capable of 2000 frames/sec. (Figure a maximum relevant rate of 15 reps/sec, and chopping each of these into 20 frames, we're only using 15% of the hardware's frame speed capablilty.) So as not to waste our benefactor's time, we'll have all of our trials laid out in advance. We'll use a grand action model with the vertical panel replaced to hold actual piano wire. We'll use three kinds of wire, in addition to the action model's 1/4" rod: 2" s/l of #13, a long thin overwound and a short fat overwound. In addition to varying what the hammer bounces off, we'll also vary regulation: slim/fat aftertouch let-off and drop, hi/lo check, weak/strong rep spring. The extent to which we'll go through all of the possible above combinations we don't know. (Remember that we'll be transfer 300 frames/sec to standard VHS video, that's a ten-fold increase in viewing time, and the 20 frames per rep is only 15% of what's available.) Michael Wathen's flexing hammershanks should be clearly visible, but we don't plan to substitute a longer key to introduce flex to that lever. We'd look forward to any suggestions y'all may have for an illuminating afternoon. Bill Ballard RPT ".....the 'Pentium Happens' bumper sticker on his Miata." NH Chapter, PTG MacUser Magazine 5/95
