Unfortunately, not yet, as it resides in another town. In the owner's experience, the modded pedal is much more responsive and feels much lighter under foot than it was with either chain or strap (he has also made custom straps for it, from some sort of tape used for printing presses).
It's high-quality custom machined parts indeed. Making the exact blueprints for the parts and the final assembly was DIY, the rest was a pro job.
