[TheForge] flypress

Thu Sep 25 07:44:00 2003

Have you seen the information on Flypresses on AnvilFire

at http://www.anvilfire.com/iForge/index.htm   in the IForge section.  Also
other information on press tooling in the IForge section.  Russ O Dell who
did this demo is a very good production blacksmith.  By production
blacksmith I mean that he really knows how to use tooling to put out the
work.  He also does great custom one of a kind work -- but is real bread and
butter is small runs of hardware etc.
