Adam,
I am using the single pulse pickup that is right on the spindle. As far as the speed control, I am just controlling it using a manual pot (the school didn't want to spend much money on this). I also burnt up the original controller and went with a miniark dc speed control on it. It takes a 0 to 10 v input for the speed control or manual 5k pot. I assume you are doing a pwm to voltage to your speed controller on the motor.
I do use the speed control on my Sieg lathe at home, but when threading, I go to manual pot also because it can be a little unstable at low speeds.
