Bending a bracelet using HSM Thin Walled Pipe technique?
I’ve completed the piercing on a somewhat delicate pierced bracelet
(think filigree but pierced), Now it’s time to take a deep breath
and start bending on the hydraulic press with appropriate dies and
lots of annealing. I’m thinking this is more probable of success
than using a rawhide mallet and a mandrel.
To try to maximize the potential for victory, I’m thinking of trying
to apply a version of the thin wall tube bending process (filling
with Cerrobend or something similar, maybe pitch). It’s a different
process because of the horizontal nature of the fill (flat, instead
of a tube). I’m having a struggle regarding how to fill a flat piece
with a heated material. The best idea I’ve had so far is simply to
try1000 mile an hour tape, fill with sand, tape the other side and
bend. The issue with sand is that it would be really hard to
unclog the verysmall cutouts after applying the pressure. Perhaps
some sort of powder, very fine sand…
Any suggestions? One member suggested bending the bracelet first and
then piercing, but I couldn’t figure out how to make that work for
my application (the angles seemed to prevent any useful lengthof saw
stroke very quickly).
Thanks, as always –
