Hi Qdog,
I am rewiring the motor with a timer which will reverse the polarity at intervals I choose. I already have a speed controller which allows me to change the speed from 2 RPMs all the way to 50 RPMs. At 50 RPMs it is turning really fast (perhaps too fast for any cheeses) but it is nice having the ability to spin that fast. The torque even at 2 rpm is very high apprx 20 kilos at 1 cm. Basically impossible to stop.
I did notice yesterday that if I manually reverse the polarity, the curds were doing really well. So I think once I get the reverable timer I am ready for prime time.
Thanks for the advise. I am hoping it will work well. I feel like after all this MacGyver will have nothing on me. So far I have built a press, temperature controller capable of handling 1 degree swings and able to rapid heat the milk from 37 degrees to 86 degrees in 22 minutes (with the stirrer on) and now I need to master this baby. Then watch out, cheese galore....lol
