I used to think that arbor presses could be bought from Harbor Freight,
Grizzly, or other "store brand" sources.
I even came close to
buying one, not knowing that it was merely a "counterfeit" machine; one
that looked like an arbor press until I had seen the real thing. As
usual, the genuine article
costs many times the price of the
counterfeit, but unlike used dollars, used arbor presses are often
quite cheap, especially if you are willing to do some minor repairs
yourself. This is what I did on a
50 year old 1/4 ton Greenerd press
that I got off ebay for $110. It was in pretty good condition, aside
from a bent handle and missing anvil.
Bent handle. The white line is straight.
Since a new anvil from Greenerd costs around $84.00, I decided to make
one of my own design. The press
has holes that I used to mount the
anvil, which is just a 3 by 4-1/2 piece of 1/2" steel plate.

most of the way through the first of three cuts.

plenty of cutting lube and
also my power

I made some accessories for this press and there are more coming
eventually. Right now I've just made a stamp holder and a center punch.
These all mount in the 1/2" diameter hole in the end of the ram. From left to right:

I never did straighten the handle. I tried clamping it in a big
vise and using a 3 pound hammer on it,
but I only managed to learn that
it is made of pretty tough steel. This speaks well for the quality of
my press, which can probably work at twice it's rated capacity, but
since it should last proportionately
longer if used within the stated
limits, I don't plan to overload it. I've also made a set of charts to
show the necessary interference for several sizes of presses. It also
has data for bending and straightening
shafts. For more info on that, click here
