Hi all:  I have to smile when I read about all the gyrations all of you
glue buffs put yourselves through to finally see the stone you have been
working on. It is so simple with wax all the way.  I put a thin shellac
coat on the surface to be dopped, preheat the initial crown surface
using my 40 watt hi intensity lamp that I use normally to inspect facets
as I progress through cutting. ( the lamp is flexible enough to move the
bulb down to a position an inch or so above the stone where it more than
is enough to preheat the stone.) I place/melt a glob of Leeco wax ( dark
brown) on the end of the dop and vertically lower the molten glob on to
the hot table. A little touch up may be necessary using a hot knife
blade after raising the stone to a vertical position on top of the dop.
Transfer is done similarly, but with less or no heat on the already cut
stone but more heat on the dop to be pushed against the shellaced
pavilion.Again touch up using a hot knife and perhaps a couple of dobs
of molten wax.  It is then an easy matter to hold the newly attached dop
with a holder and heat the original dop near the stone and apply a
little pressure to release it.  Then clean up with a hot knife. ( I use
an alcohol lamp for heat).
I can see my finished stone in two to three minutes after I'm through
Wax failures are extremly rare.  By the way, the final release is
accomplished by heating the dop below the wax while your finger is on
the stone table.  When you feel heat through the table for a few
seconds, remove from heat and count to 20 or 30  or 50 ( depending on
how fast you count and how big the stone is) to allow the wax to absorb
enough heat that merely scraping with your fingernail will peel 98% of
the wax away.  Then it is a matter of just a couple of minutes in
denatured alcohol and your stone is ready to wipe clean.
Re; The question about spessartine vs. spessartite,   it has always been
my understanding that spessartine garnet can be called spessartite.....
not spessartite garnet, but just spessartite.  ie., spessartite =
spessartine garnet.
Happy faceting,     Jerry Newman

It was stated here recently that propylene glycol is NOT toxic.
The Material Safety Data Sheet (MSDS) for Propylene Glycol states: 
"Implicated in contact dermatitis, kidney damage and liver
abnormalities; Can inhibit skin cell growth in human tests and can
damage cell membranes causing rashes, dry skin and surface damage. "
Acute Effects:  May be harmful by inhalation, ingestion or skin
absorption.  May cause eye irritation, skin irritation, exposure can
cause Gastro-Intestinal disturbances, Nausea, Headache and Vomiting,
Central Nervous System depression."

If you wish to use it go ahead, but do not consider it safe. It is SAFER
than ethylene glycol but it is still somewhat dangerous. Use mineral oil
and a respirator if you are worried about oil mist.


Subject: Raytech Handpiece Binding

From: "Rick Hendrickson" <charh@earthlink.net>

     Has anyone had a problem with their Raytech handpiece becoming
difficult to index? The machine is not quite a year old and has operated
beautifully. Last week, seemingly over night, indexing has become quite
difficult. So difficult that I must hold the indexing trigger with my
left hand and use my right hand to turn the index wheel to each
successive setting. The imprint of the index wheel is left on the finger
doing the turning.
     I have even removed the index wheel,etc but the binding action is
still present.On a 96 index, the binding action is most severe as one
approaches 12-15 settings but is still very difficult on the other
     I am reluctant to attempt a disassembly of the handpiece/quill
assembly without knowing what the problem may be. Any help with
identifying the possible problem would be greatly appreciated.
My thanks in advance,
Rick Hendrickson
