Making
a small home shop press
Here's
a little 2ton hydraulic press I made for a friend:
I used some 1/2" plate, a couple sections of 7/8" cold
rolled rod, and some springs and hooks. Oh, and a 2ton jack (of
course).
I'll be making a bigger one for my shop at some point. This little
guy will be very useful though. Make up some dies and jigs, and
away you go.
With a little press like this and some jigs you can bend metal
bar, plate, tubing and such to various angles. It can also be
used for pressing on and off bearings, u-joints, and anything
else that you can think of that will fit.
There's not really a lot to it, although I did make a couple goofs
along the way. That usually happens when I whip something up off
the top of my head. For a larger unit I will spend a little more
time on the design. Maybe even draw it out.
The
first set of springs I used (pictured) were just some springs
I had kicking around the shop. They weren't quite as stiff as
I would have liked. I had some that I scavenged from a dumpster
(I think they are bed springs) that I was going to use to replace
these, but instead I ended up installing another set of springs
inside the springs pictured here. That worked quite well.
When you release the hydraulic pressure, the press plate returns
to a resting position with the jack completely collapsed (unless
you turn the valve to stop the jack at a desired height).
Just decide what you are going to use it for, and design around
that. Some people use threaded rod and nuts instead of solid bar
for the uprights (mine are TIG welded). I've seen some that have
the jack on the bottom, and others that only have a base plate
and a top plate, using the base of the jack as the top press surface.
Have some fun with it, and come up with your own design.
