[TheForge] flypress

One major difference is the screws.  Most screw presses or tryout presses
used in a die shop are built with a single tread on the screw (screw tread
starts at on point.)  This is slower acting but produces high force or
tonnage.  The flypress now being sold for blacksmithing have  mutli tread
screws.  Some up to four treads starting at the same point.  They have 4
time the lead for the same pitch of thread.  This means that the screw
advances 4 times as fast as a single screw.  Still a lot of force but not as
much as a single tread -- but 4 times the speed.  Said to be "better" for
forging.  Really depends on what you are doing.
