[Engraving] Filling crushable hollow objects


#1

Any suggestions to fill crushable hollow objects while I engrave on
the exterior? Something that would take vibration and remove easily
and cleanly? Pitch…yuck! Maybe a hard wax? Help appreciated,
Thanks, Brooks.

Brooks: a solution other than pitch I heard about in a raising
workshop is to use Protoplast. The beads are the best. You heat them
with hot water mash them in the container till its full let it cool
and hammer away. To clean just reheat in water till soft and remove. i
have been using it for holding diamond setting and engraving in place
of shellac. Available at

WFN/Aquaplast Corp.
30 Lawlins Park
Wyckoff  N.J. 481-1443

I have also had great success burning this plastic out and casting.
Hope it helps. Frank Goss

Hi – Have you tried that new material called Thermo-Plast yet?? I
have only just started playing with it, but it’s pretty neat – it’s a
type of plastic pebbly material that forms/solidifies into any shape
you need in hot water and then keeps that shape as it cools down. You
can use it over and over again by just plopping it in hot water. I
bought mine from Swest late last year, but I just got a flyer from Rio
and they are now carrying it.

Your wax idea sounds good. You could inject them with injection wax
and melt it out when you are finished.

Try out Plastiform, available through Frei & Borel, Setter’s Grip
from Gesswein, Jett Sett from Rio Grande or the traditional orange
flake shellac available through most jewelry suppliers. The malleable
plastics are fun to work with for all kinds of projects, not just engraving tasks!

You might try that new “Jett Sett” plastic material sold by Rio
Grande and Frei and Borel. It softens in water at 180 degrees and is
then formable. I just ordered some after seeing it demo’d at the
SNAG conference. I think F&B has the better price of the two, but
things change. try www.riogrande.com (don’t know if Frie & Borel have a web site, anyone?).

G’day; What about trying domestic (desert) jellies, made up very
strongly with hot water, poured into the vessel and allowed to set.
Remove by standing the vessel in very hot water. Just my thrupence
worth. You could eat it afterwards. Waste not want not. Let’s know
how you get on. Cheers,

I, too, saw Jett Sett demonstrated by Rio at the SNAG conference,
have ordered some and just formed graver handles from it. I love
working with it. However, my understanding is that it becomes too
hard to chase against - there is no give. I’d be interested to hear
if anyone has success with this technique! Gini

Hello Brooks, A traditional method is to use shellac. It is available
from tool houses in flake form. You stuff the piece as full as you can
and then warm it. The shellac melts and sticks to the object. When you
are through, warm the piece again to let the shellac run out. Be
careful about where it goes, it burns like the dickens. Soaking the
object in denatured alcohol will get the remaining shellac out. Have
you considered just leaving it in? Have fun. Tom Arnold

Yep, it isn’t designed for chasing and repousse. I use pitch for
that Jett Sett (and other thermoplastics) are good for holding,
supporting, making dies and handles, you catch my drift. It’s in the
promotional literature about the product. . Check the archives at
Orchid for a supplier of pitch. The commercial stuff doesn’t even
resemble good chasing pitch.

to go… see you calgang
