[TheForge] Suggestions needed for scroungeable steel

Wed Nov 19 08:48:01 2003

Pete,
This particular TH will be quite simple.  The ram face IS the hammer
face.  No upper tooling.  Hence it needs to be hard enough not to
mushroom when it strikes a tool.  I expect to harden and temper it like
an ordinary hammer face.

Bruce:
I'd respectfully argue that a hard face on a treadle hammer is not 
desirable. A softer face will "stick" to a struck tool allowing greater

latitude in alignment. With a hard face, more struck tools go flying to

mysterious locations where they hide for years.    Pete F
