Just Arrived. HM Rotaries to FK Irons

[fkirons]

hey fk how do they run as far as speed?? what would you relate the motor and stroke too, since you have used most rotary's out there

as far as speed, I don't know exactly the rpm but around 6-7volts depending what I want to do.
The stroke is about 3.5mm if I do a black and grey piece i hide the needle where what I get off the tube is about 1-1.5mm.
For lining I crank up the speed and hang about 2mm out.

Hope that answer your question.
