another twist-core

[DaveS]

Gustav: A deep topographical acid etch to create a twist pattern is
completly different than a manipulation of a bar of iron and nickel
to create a desired pattern. The twist core kris i posted last week
was done in an entirely different way to get that pattern, then it
was etched to bring that pattern out. A deep etch using acid and
some kind of resist is the same as seen on some swords and
"damascus" gun barrels.........Dave.
