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
cutting.
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

Subject: propylene glycol

From: "Beth & Doug Dover" <ddover@carolina.rr.com>

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

To: <faceters@caprock-spur.com>
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
settings.
     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

Q: Why do bagpipers walk when they play?
A: To get away from the noise.

Q: What's the only thing worse than a bagpiper?
A: Good question. We're still trying to find out too.

Bagpipes (noun) - I understand the inventor of the bagpipes
was inspired when he saw a man carrying an indignant,
asthmatic pig under his arm. Unfortunately, the man-made
object never equalled the purity of sound achieved by the pig.
-Alfred Hitchcock

Q. How do you get two bagpipes to play a perfect unison?
A. Shoot one.

Q. What's the definition of a minor second?
A. Two bagpipes playing in unison.

A. No one cries when you chop up an bagpipe.

Q. What's the difference between a bagpipe and a trampoline?
A. You take off your shoes when you jump on a trampoline.

Q. How can you tell a bagpiper with perfect pitch?
A. He can throw a set into the middle of a pond and not hit any
of the ducks.

Q. How is playing a bagpipe like throwing a javelin blindfolded?

Q. What's the difference between the Great Highland and
Northumbrian bagpipes?
A. The GHB burns longer [but the Northumbrian burns hotter]

Q. What do you call bagpiper with half a brain?
A. Gifted.

Q. What's the difference between a lawnmower and a bagpipe?
A. You can tune the lawnmower, and the owner's neighbors are
upset if you borrow the lawnmower and don't return it.

Q. How many bagpipers does it take to change a light bulb?
A. Five, one to handle the bulb and the other four to contemplate
how Bill Livingston would have done it.

Q. How many bagpipers does it take to screw in a lightbulb?
A. 5-one to do it, and four to criticise his fingering style.

Q. If you were lost in the woods, who would you trust for
directions, an in-tune bagpipe player, an out of tune bagpipe
player, or Santa Claus?
A. The out of tune bagpipe player. The other two indicate
you have been hallucinating.

Q. How do you make a chain saw sound like a bagpipe?
A. Add vibrato.

Q. How many bagpipers does it take to change a light bulb?
A. Five. One to handle the bulb, the other four to tell him
how much better they could have done it.

Q. What's the definition of a gentleman?
A. Someone who knows how to play the bagpipe and doesn't.

Q. Why do bagpipers leave their cases on their dashboards?
A. So they can park in handicapped zones.

Q. What's the definition of a quarter tone?
A. A bagpiper tuning his drones.

Q. What do bagpipers use for birth control?
A. Their personalities.

Q. What's the difference between a dead bagpiper in

A. Drool.

Q. What's one thing you never hear people say?
A. Oh, that's the bagpipe player's Porsche.

Q. Why do bagpipers always walk when they play?
A. Moving targets are harder to hit.

Q. How do you know if a bagpipe band is at your front door?
A. No one knows when to come in.

Q. Why did the bagpiper get mad at the drummer?
A. He moved a drone and wouldn't tell him which one.

Q. Why are bagpipers fingers like lightning?
A. They rarely strike the same spot twice.

Tom: "Hey, Buddy. How late does the bagpipe band play?"
Buddy: "Oh, about a half beat behind the drummer."

Q: What's the difference between a Scotsman and a Rolling Stone?
A: A Rolling Stone says "hey you, get off of my cloud!", while a
Scotsman says "Hey McLeod, get off of my ewe!"
