For Bill.......the opal expert.
In general,   do you think it best to cut an irregular shaped piece of
rough into an irregular shaped cab,, or sacrifice some of the material
to get a perfectly shaped standard sized cab?    I realize that it
depends greatly on what you're going to use it in, but just in
general.........considering only the stone.........which do you think is
the more sensible route??

Bill B.  Thank you for the succinct basic education
regarding opal doublet and triplets.  Do you mind if I
paraphrase your explanation to others? It's what every
beginning opal consumer needs to know.  Connie

Hi Jill,

I couldn't read your email address in the lapidary newsletter, so here is
my response:  Your submission caught my eye.  I am a facetor living in
the Raleigh, NC
area.  I live in Apex, which is right next door.  I am also a member of
the Raleigh Tarheel Gem and Mneral Club, where my interest in faceting
started.  If your friend would like to contact me, my information is
below, if she would like to see our website, assuming she has internet
access, here is the club's address:  www.tarheelclub.org.

Best Wishes,

Hi List Members

I would like to recommend this cut which is worthy of consideration by
Faceters searching for a simple but very rewarding round design for high RI
material. Although the indices are familiar the angles determined by Vic for
cubic zirconia produce a nice balanced display of colour, fire and
brilliance from the finished stone. Over the years it has been cut in a
variety of sizes and produces excellent results from the lighter materials.
It has been successful in several aesthetic appeal competitions.

Subject: Ultratec Dial Indicator

From: "Wayne S. Barnett" <wayneb@ev1.net>

Does any one have plans and/or instructions on how to construct and install
a dial indicator for a left handed Ultratec.  The company no longer makes
them and at what they were asking before being discontinued was quite
expensive.  A friend had an dial indicator installed on another brand of
machine quite reasonably.  So know that it should not cost an arm and a leg.
Would prefer to have a setup that would not involve drilling and tapping
into the facetor.   Any assistance would be greatly appriciated.

Hi Steve,
Re:  spectroscope information

You might want to get Dr. William Hanneman's "Guide to Affordable Gemology"
$25.00 (The forward is by Dr. Frederick Pough).  (Dr. Hanneman does have a
catalog of all his instruments, books and reprints for free.)

In his book, he tells you how to make some of your own instruments or you can
buy them very affordably from him.  For instance, the specific gravity
balance that he designed is more sensitive then the $3000-4000 models.  I
have used both.  I bought my balance from a company that now makes them for
$100.  But, his book gives you all of the information necessary to make your
own for a lot less.

I bought his OPL diffraction grating spectroscope for $65.00.  I am not
proficient with it because I have not taken enough time with it.  I don't
feel that it is any more difficult then the expensive model which I have

My next interest is to get his reprints on "Basic Gem Identification using
the Hodgkinson Method"  DR Alan Hodgkinson, who is, I believe, at the
University of Edinburgh, Scotland, devised a method of identifying stones
using only your eye, the stone and a light.  When I went to visit DR
Hanneman, I took a stone that I wanted conformation on it's identity. He held
the stone up toward the light and after 15-20 seconds correctly identified it
as synthetic spinel!

Richard, on the subject of your dished saw from jade sawing, I was just
looking something up in "Gem Cutting" by John Sinkankas and came across
an item that I don't think anyone has mentioned yet.  When you first
start cutting with the gravity feed saw you should not have weights on
your feed, just gentle hand pressure as the cut is started.  Then after
it gets the cut started, put on the weights.  The tougher the material,
the slower the feed should be, of course.
  On the other hand, if you are expecting the blade to start cutting on
a rounded surface, the blade may slip over to the side instead of going
straight in.  You can avoid this by (1) picking the flattest surface to
saw into (2) grooving a curved surface by moving the oily sawblade
manually back and forth across the face where the cut is to begin.
Hope this helps.  Rose Alene McArthur

Just a quick note on saw blades. I have just come across 12    Norton
Diamond Wheels......These are used blades from a local manufacturing
facility. They were used for metal cut off and relieved of duty after
tollerances fell out of spec. The number is M4D60-N100M-1/8
7640 RPM         8"  X  056  X    1 1/4"   continuous diamond.
All in great shape and 90 percent of diamond left on wheel. I purchased the
1 1/4" bronze washer at true value hardware for the center hole to reduce
them to 1/2"  arbor size....
I have been using these blades for a couple years and love them...Granted
only 8"  but more than large enough for many tasks... They are extremely
sturdy blades and  do not flex much in a heavy cut....Also have not bound up
with rock dust so far...
Let me know if any of you need some.. Cheap............
