yes, but I want more than one pulse/rev... for closed loop speed control you can't have too much information... and a sensor on the fixed gears may well be easier...

Note: if anyone reading this has a minilathe with built in rev counter... how is it done? Are there any useful parts that could be acquired as spares? I had a quicl browse for a parts list online but all of the ones I found don't detail the rev counter...
