[TheForge] Hydraulic Forging Press

Wed Mar 12 17:28:01 2003

I scaled up the principles in the batson design guide to use a 7 1/2" 
trunion cylinder, resulting in a c-frame with about 50T force.  It will 
out forge my #50 Little giant by a lot.  It is great for heavy 
forgings.  Light forging is tricky on it because the dies cool the work 
much faster than a power hammer does.

I've built cold punching dies and cold chamfering dies as well. 3/4" 
holes in 1/2" stock are easy to punch cold.
  With 50T you can do quite a lot of forging without heating the metal. 
It can be particularly nice for doing chamfered square stock for 
curtain rods - the cold working stiffens the rods quite a bit and 
allows for longer spans with fewer brackets.

Lately i've been doing more cold cutting and chiseling of shapes from 
plate. Handy.
