[TheForge] Fly Press

[Chris Worsley]

What?
My fly press (an Adams #2) ram screws down as the overhead weighted bar is 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.

Mostly because I 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?
