[TheForge] Mechanical Power Hammer Plans

[Jonathan Barnhart]

>From what I've seen they adjust the throw on this
style of hammer by using threaded rod and turnbuckle
on the throw arm.  That way you can adjust for longer
or shorter distance.  I hadn't tried to buy plans,
but, I don't plan on that for sure now.  Has anyone
tried some sort of foot pedal Rheostat to control the
motor speed instead of the various treadle and clutch
designs?  I was thinking of something like the kind
they use for trolling motors.  I figure that would be
a bit heavier and last longer than one from something
like a sewing machine.
