This is my first Air Hammer, I just finished it over Christmas(2000)!
It was built with the
ABANA plans from Ron Kinyon
, using the reduction plans from
Larry Zoeller
, part of the
air system plans from AFC
& many of my own modifications to fit my ideas and the materials I
had handy. Most of the parts are scrounged from local scrap yards
& flea markets! The main body is a 16" X 7.25" I-Beam. I
cut out & faced the work opening. I had to add some spacers to
the hammer head because I forgot to account for the 3" extension that is
supposed to be on the cylinder rod, the cylinders I found didn't have it.
The hammer head is 35#'s. The anvil is a piece of 5" round, cut from
some kind of axel I found at the scrapyard. The cylindar has a 1.5"
bore, 5/8" shaft & 11" stroke, made by Parker. I'm getting about
200 strokes per minute on this!! I'm only using a small 5hp, 30 gallon
Craftsman compressor & it keeps up just fine for me. I'm using
a foot treadle like on a Little Giant for control. I have excellent
control with this system. I can get very light hits or very hard hits
or anywhere in between. I can get single hits very eaisly also, so
it eliminates the need for a treadle hammer! Actually, I'll probably
build a treadle hammer one of these days too!
I used the 3-way valve that Larry Zoeller called for in his plans.
I'm not sure how much difference this valve makes over a regular ball valve
with a spring return. I'm thinking that the ball valve would work
just as well for much less money. One of these days I'll probably
put one on there & use the 3-way for a pnumatic vise or something like
that.
I have links to ABANA and Larry Zoeller's pages on my links page
if anyone is interested in building one or seeing the plans I used.
Please feel free to E-Mail me with any questions, I'd be glad to help
anyone who wants to build one of these.
