Here is my version of the Mini Press. It took me way too long to put it all together...but it turned out well. Many used 2" square tubing for the base, but I had a piece of 10" wide channel. It has a piece of 1" plate cut to fit the channel and welded across the center to support the cylinder. Only have 2 sets of dies made up so far but will make a bunch more as I go along. The air valve for the cylinder was put into a foot operated air switch which lets me hold my hot work and operate the hydraulic release on/off.
I had it on a small steel stand but it was not easy to move. So I cut part of the off and mounted it to an old horizontal dolly that I had. Now it can be moved out of the way when not in use.
Now that it's complete I'm thinking I want a bigger hydraulic press.
