[TheForge] Upside down Press - oh what a tangled web we weave

[Bruce Freeman]

No, that's not what I meant at all.

The idea is to fix the lower die in space and let the rest of the apparatus move up and down.  This would be done by means of an external frame around the "press proper".  Hence, there would be very little change to the orignal design.  The "crush" would occur on the extension, as in the original design, NOT on the retraction.

What this buys you is a stationary lower die, without loss of most of the rest of the features of the "upside-down press" design.  For what that's worth...

 --hmmm---he says well scratching his head:
If I understand the idea, the lower die is fixed in space, the cylinder is
no longer inside the frame but attached to the base, and the frame moves up
and down. The crush occurs during the retraction of the ram rather than on
the extension. <large snip>
