Guy I work with is wanting to build one and being a machinist I am
going to help. Neither of us knows what y'all use to vary the speed.
this is being made with scrounged materials so what can we make this
out of or where could we get a good deal on whatever controlls the
speed. Or maybe some drawings somewhere

Thanks for the tip. This seems to be exacly what my friend is talking
about. I still don't understand about the speed controll. Is the speed
coming down doing the hammering constant and only the speed going back
up that varies? Or do you want to controll the force sometimes and
vary speed coming down? I'm just building some of this and don't know
anything about their use.

I'm pretty sure it's the repetition rate that you vary. One real nice
thing about the air hammer is that you can make single blows it you
want. This is harder to do with a shaft and crank trip hammer, unless
you install a brake.
I don't have one of these myself, but have spent time talking with
Ron Kinyon about these hammers and have found him to be very helpful to
seroiusly interested folks. I think Ron sells control sets, too.
If your friend is going to invest time in this, I suggest he get a
set of the ABANA plans mentioned in one of the links.
Here's the exact link: > http://www.bookmasters.com/abana/plans.htm
