[TheForge] 15Ton Press

[Steve Smith]

Consider putting the cylinder on the bottom and having a fixed top die/moving
bottom die. Steve Rollert has his press that way and it works fine.

I have a C style 35 ton press with the cylinder on top. It is over 7' tall and
weighs a ton (well, not that much). It would probably weigh a third as much if
it were both H frame and cylinder underneath.
