ok so im not sure if this is the right place for this thread but.........i want to talk about machine speeds vs voltages on rotaries of course not realy sure hot these two relate i build coil machines and i know that on a coil if u raise the voltage it makes the machine hit harder not faster to change a coil machines speed u have to use a stiffer front spring since rotaries have no front spring how does this relate i know on a rotary if u increase the voltage it increases the speed but it still hits the same so am i some what in the right ballpark with this theory
