I built it because i could. It is fitted with gliding linear slide carriage bearings, has a counterbalanced offset crank with needle bearings, a jackshaft to drive it from a variable-speed dc motor, and even a variable stroke length (which was tricky). Above all it has something i haven't seen in any of the machines one can buy, a bendable, collapsible coupling that would prevent injury to whomever is on the receiving end of the stroke. Clearly it will never be placed into production as it would cost too much to sell at a typical consumer price level. May all be for nothing because i can't get anyone to let me try it out, and i'm only accepting female applicants from among people i know. It's my machine. Sue me. This file is only 2. 6 seconds in length. If you use audacity to repeat it as i did, it will mesh perfectly together to give you any length audio file you want. I did that to produce "v2-reciprocating machine. Wav. ".
