[TheForge] Power hammer Vs air hammer

[dave mudge]

Grover, you are correct about the potential danger of air hammers.
Just like a motorized mechanical hammer with the on/off switch mounted near
by
your air hammer should have a ball valve (on/off switch) located right on
the hammer.
I have a red light that goes on when the hammer is energized and off when
there is no pressure.
http://www.magichammer.freeservers.com/page31.html will show you a picture
of the
light. You can find a light here: http://tinyurl.com/pvjl6

search for item number LK1505 The air pressure / electric switch that I used
is a
homemade device (engineered by Byrne Lobdell) from an old air conditioner
window unit.
I think that Granger has a similar switch.

	Thing to remember is that a power hammer, when it is running, is
obvious and dangerous to the casual observer.

	An air hammer, when running, is a rat trap waiting to be tripped.
At a meeting last Saturday, I announced the danger of an air hammer.  In
that it is armed and ready to go, and the air compressor is 2 buildings
away.  There is no obvious sign that an air hammer is ready to work, other
than the fact that the air lever is moved 90 degrees, or the wood block is
underneath the foot leaver.  Non-blacksmiths would miss such signs.

	Not long after, someone (I leave the name out because I almost did
the same thing years ago) stepped on the operating lever.  It moved.
Immediately the wood block was re-placed underneath the foot leaver.

	Air hammers are good, but can be a silent killer when visitors are
in the shop.
