PIE 4.3 Disassembled for Analysis & Repair

I have disassembled the PIE 4.3 to analyze it for defects and to replace the drive pulley with a roller chain sprocket. Although the weights are very light, there is more than enough inertia to cause significant damage when things go wrong! Be sure to check out my blog and new website (still under construction) at www.stclairtech.tech https://grassrootsmechanicmovement.blogspot.com/
Note: As I progressed through these many experiments, I have made well over 100 videos. All of them are on YouTube and many are also on BitChute. As these are disappeared on other platforms, I am uploading many of those here to keep the info public. B-
