Hi Steve, all,

Any idea how the solenoid is activated ? what makes it vibrate ? and
does it run at 60 hz or some multiple ? or is there some external
occilator that drives it ?

I have seen those larger tap busters on e-bay, but they run into the
hundreds of pounds of metal, so the shipping would be horrible.

A hose connected to an EDM that is once thru and washes out the chips
is not as bad trying to recycle water with a pump.
