Here is someone's attempt at a progressive lockout?

Dennis Page, a retired high school friend who was helping me with the device in the following picture, didn't quite get there - the devil was in the little details and close tolerances in the mechanical parts. I'm sure he could have dealt easily with user adjustable programming an Arduino to provide the speed input I planned to pick up with a sensor reading CV bolt heads. If we kept at it I believe we could have made it work. But alas, I lost interest and concluded there was no market given the success of spring loading (along with removing the slop from the shift coupler bushings) in fixing the stock shifter's sloppiness. You would need (or at least want) the extra spring loading in any event (you can just see part of the Seine in one photo).
