[TheForge] Power hammer questions

Go the Krause method for a low noise air hammer, or put the compressor
outside the shed and plumb the exhaust outside also. You can get a variac (I
think thats what they are called) to vary the speed of an AC motor thus
varying how hard you hit but also lower BPM, but why not use a clutch, its
probably the easiest method and a car differential via the handbrake is a
great way to do this, I built a JYH using this method, pics on anvilfire,
the clutch worked pretty well.
