I recently added a Harbor Freight 20 ton press, used it for a couple of projects, and decided that it was relatively hard to adjust the workpiece for the proper vertical position. So I had a few 2" and 2.5" round rods not doing anything. and since the Takisawa really does well on steel parts, I machined a small protrusion on one end of each rod and a recess on the other, and the diameter (a very loose fit) also matches the press ram. This lets me stack up a collection that fits closer to whatever work piece is involved. I can hold the lowest block in position and not have to balance/juggle the stack if I tip a little bit. .
Also, per others suggestions, I made a knob to eliminate flipping around the jack handle to work the hydraulic release valve. That's faster too.
