If Tim remembers Chris' mechanism more clearly than I do, maybe he can give you some details.  The thing that made that series of demonstrations so phenomenal was the ability to so precisely control the blow.  If memory serves, there is a pretty good engineering school at BYU - maybe some enterprising students could come up with something in their (copious) free time. I don't think that Chris would present his work as being the end of the experiments - rather, as places from which to begin. Pinning makes a difference.  Now you have precisely the toy, errrr, tool, to demonstrate that fact. I wonder, given the changes/advancements in computer technology since Chris did most of his work...perhaps there is a way to more graphically represent things, real time, as well as getting the numbers out.  The analyzer Chris used was a B&K, with numbered lights for a read out...very useful; but a little more difficult to immediately apprehend.
