I was just wondering how a 20 ton press works. I friend of mine
was talking about building such a beast and I was curious as to
how they are put together. What does it use for powering the
Jeff, I just finished taking a class from Lee Marshall
(BonneyDoon Mfg) He has the best hydraulic press-made especially
for jewelry and metalsmiths.
The book that he recommended to read before the class, was Susan
Kingsley’s book “Hydraulic Die Forming for Jewelers and Metalsmiths ”
In the book there are pictures of a do it yourself
press and the Bonney Doon press along with a schematic on page
77 of how a press is assembled.
It also has wonderful reference tables in the back for cutting
the correct angle for each gauge of metal you use.
The book is a wonderful resource for examples of some of the
things you can do with a hydraulic press. It opens up a whole
new area of thinking.
You can get it at Amazon.com but it is probably quicker to order
it directly from Susan at 20-Ton Press P.O. Box 222492 Carmel,
Hello out there to anyone who has recently taken a Hydraulic
Press workshop with Lee Marshall! He has recently started a
chat room on the subject that I wandered into just yesterday,
and it promises to be a great resource of once it
gets rolling. I am a novice with the thing and while many
purchase a press with a specific goal in mind, my only goal was
to go into a totally new direction with my work. I am still in
the design mode, but am only days away from actual use. The
workshop was truly terrific, with folks from a variety of
backgrounds, all anxious to learn from Lee. I think it would
be helpful to take the advanced workshop at a subsequent date.
