[TheForge] Fly Press

Yeah I thought a fly press used the weights as momentum and when the dies
hit the work the coarse thread "toggles" to a fine thread and presses the
work, then you can use the leverage of the arms to press some more with your
own muscle.

turned clockwise and goes up when I reverse the direction of the bar. One
course threaded screw does it all. Sounds like what you are calling a screw
press, but it is a "fly press" by all who know it.

curently don't have any poser to the shop & the house is all solar power.
Non-power tools are a bit easier to make use of right now.  Any body have
any experience or thought regarding the Fly Press?  How big of a press would
be useful for the average shop (I know it all depends, but a good starting
point would be nice)?  Are there any advantages of a Fly Press over the
Hydraulic Press?  Finally can a large Fly Press do everything a small one
could do, or are they to much for the more delicate work?
