[TheForge] shapers

[Grant Marcoux]

Steve:  The A2 and D2 are fine for cold work cutting, assuming proper heat
treatment.  The H13 is designed as a hotwork steel and is not typically
hardened for cutting tools that are used in shapers.  Granr

Bill W. - I sent two interested parties your way on your line-shaft Hendey.
I recently purchased a 14" Varnamo (Swedish) shaper after hearing for too
long how useful they were for dovetails, etc. It's my first machine tool and
I am absolutely in love with it. Worked some stock to make a set of T-nuts
for the table today and am eyeing some 4340 chunks for a new set of flat
dies for the kuhn. If only I had this thing when I made my first Kinyon in
'98. It almost makes me want to build one all over again.

Anyway- a question for the group: Right now I'm using standard 3/8" sq. HSS
bits and am wanting to explore the use of different tool shapes for creating
radii, etc. I have some A2, D2 and H13 and while these seem like great air
hardening steels are they as tough as HSS? I know M2 is a given for cutting
tools, just not sure about the others.
Thx,
Steve Howell
