[TheForge] Re: Powder Damascus

[Roger R Degner]

UMBA library has a couple of demos of powder damascus one  by Peter
Martin and the other by Jim Batson.  Cost is $5 each plus $2 shipping
Looks easy the tough part is ;compressing the design evenly so it looks
like it is supposed to in the end.
It is a lot cheaper than EDM work 
Most use thin nickel sheet as the powder separator although Jim said
just standard paper card stock would work it just leaves a fuzzier line
between the two types of steel due to carbon migration.
Both used super glue to make the pattern for the design

Do you mean that knife makers are doing powder metallurgy in their own
shops?  If so, I'm further out of touch that I thought.

Or did you miss the point that this stuff is being built up by layering
up two kinds of powdered steel, making a single press weld to sinter it
together?

I've made a number of trashed billets and couple of blades in the
traditional way myself, including the one I gave to Peter Happny that
made by welding together an antique 1-1/4" open end industrial wrench,
half a pair of wrought iron tongs and the cover from my rusted out tin
wood stove.  (Oddly, that mess worked better than some of the more
carefully planned attempts.  Part of the smashed stove top, half the
wrench and part of the tong rein project from the blade, offering
various options for a grip, none of them good. :-)


BTW, does anybody know an email address for Peter or Lisa?  Or are they
strictly off-net folks?
