Mike asks: I hope I'm not too much trouble. I was just wondering what diameter of pulley you ended up using with the HXT. What a pain, trying to find a 12mm one! According to my calipers, it's actually like 11.8mm, even better.
I used a 1/2" imperial pulley on my 12mm nominal motor axle.
1/2" = 12.7 mm. So you can use the imperial if you make a small shim out of brass or aluminum stock. I found the sides of a soda can worked great.
I also machined a notch on the axle so that it would grab the little allen bolt better.
