Hi Jess, what an interesting idea - to use the hammer handpiece as
a holder for an engraving tool!
I have an older Kavo hammer that I’ve only ever used for bezel
setting and rivetting and impact-type texturing. It has insertable
heads which screw in via a 3mm thread. I bought a matching tap and
die set so that I could make up my own points, but never thought to
apply it to a graver.
The more I think about it, the more I like it. It will be easy
enough to soften the tang of a short (read almost worn-out) scorper
or graver, adjust it to take the 3mm thread, re-harden and temper,
and voila! My Kavo has four settings and my guess is that the
lightest setting at fairly high revs would be sufficient to drive
the graver nicely through the metal.
Gosh! I hope you haven’t patented the idea (bad joke). I’ll trial
it before someone tries to lock the concept away from the rest of
us and let you know how it works. 'Donya Jess! Regards, Rex from Oz.
