I am SUPER PUMPED! Totally completely pumped. I can smell the end and it's not burnt wire insulation either! Pictures will come later when I get home, but in the meantime:
1. gave the motor a coat of black paint to spiff it up. Looks rather nice now.
2. fitted the drive into the alu case I bought, heatsinking the whatsits to the case so there's a ton of surface area for cooling
3. wired in one of the DPST switches and it works and glows
4. trued up both pulleys, which will hopefully reduce vibration as much as possible
5. tested the tach and it works a treat, although 3000rpm is a little scary!
6. and best of all, cutting resistor R19/ RPS3 (connected to the wiper post of the pot) does away with the need to zero the pot to start the motor. It now starts at the same speed. How cool is that? Even found the same resistor (I think) on the MC40 board from my old treadmill. Woohoo!
Starting to do the lay out on what goes where in the control box. Haven't figured out how to attach it to the bench yet though..
