Hi Brian

Your problem was in the motor speed control, the poor thing is stuck on top whack

I clocked it with the jolly old digi-tacho and it is doing 10,600 rpm. Air cooling? Liquid nitrogen might have been a better bet :rofl:

I cleaned the shaft encoder and the rpm display burst in to life. Still can't slow t'bugger down though because the speed control pot is worn out. Can't be bothered to replace it because I'm planning on reworking the speed control anyway.

Not complaining, I do this for fun. Best of all, it has passed wifely inspection as white goods and been approved for desk top use in the warm. My cup runneth over

best

Robin
