I missed a couple of issues and I'm not sure who is actually looking
for the San Carlos material.. but the contact was Charles Vargas of
Apache Gems. I'm forwarding a copy of this to Hans Durstling who
visited with Charles Vargas while working on his Canadian Discovery
Channel series on gemstones to see if Hans has current contact info.

A friend of mine who has been out of faceting for a while wants to get back
into it in a big way with sunstone. He's asked me to locate a source for
top sunstone (non-shiller, red) rough and wants to buy kilo amounts. Any

Subject: New member bio.
Date: Sat, 13 Nov 2004 09:38:14 -0500
From: Jim Perkins <email@example.com>
As a new member to this list I thought I would submit a brief bio. My
name is Jim Perkins and I began collecting and cutting rocks, minerals
and fossils about 44 years ago at age 10. Today, my primary interest is
in faceting and sphere making.
Some of you may know me as an Ultra-Tec authorized faceting machine rep.
Some may know me from my monthly column in Rock & Gem Magazine, OFF THE
DOP. Perhaps, some of you may have met me at a rock show or club meeting.
For those who do not know me I enjoy making my own designs using GemCad
by Robert Strickland and FACET DESIGNER SOFTWARE by Anton Vasiliev. I
also enjoy exploring optical performance of my designs. I enjoy cutting
sapphires and garnets in particular and have recently found a new
interest in cutting quartz gems because of recent discoveries I have
found utilizing odd symmetry and the 72 index gear. While I am not the
first to explore these ideas, I am the first to report on them.
I am a member of THE U.S.F.G., The Mid-West Faceters Guild, A subscriber
to THE TOMOKA FACETERS GUILD "CUT OF THE MONTH" (which by the way I find
Philip Stonebrooks monthly analysis particularly informative ).
I have recently written a new paper for distribution to local schools
ANALYSIS OF QUARTZ FACETING DESIGNS WITH EVEN AND ODD SYMMETRY. I have
also recently published five books of my faceting designs and made them
available in printed versions and also on CD-ROM in .gem format for
those who like to do their own analysis and or modifications of designs
for their own purposes. Those are available from Rob Kulakofsky at:
Professionally, I own a Metrology sales/service company which sells
Optical Comparators & Measuring Machines, geometric computational
digital readouts and related items to industry. We also calibrate the
measuring equipment traceable to N.I.S.T. I have written one book on
Optical Comparators and their applications. I am currently writing some
other books however, creating books is a passion rather than profitable
so progress is slow. I also write a monthly column for SHOP TALK
MAGAZINE by Magellan Publishing called EYE ON OPTICS. I feel my
relationship between my hobby and my profession is no accident.
I seldom sell stones I cut and when I do it is usually only to a friend
of my wife or one of my daughters.I primarily enjoy cutting created
stones (not simulants) however, I do cut some natural stones too. Most
of my stones are cut for my own collection or as gifts for family and
friends. I enjoy speaking publicly to clubs, guilds, schools and
organizations I periodically donate materials or specimens to local
schoools. I enjoy teaching lapidary and GemCad whenever I have time and
feel the person I will teach is properly motivated. Since time is my
most precious resource I don't like to waste it. I am a great admirer of
Glenn & Martha Vargas and their contributions to faceting. I also
greatly admire Robert Long & Norman Steele. I have been fortunate to
meet and spend time with many of the world's most accomplished
competition faceters and designers living today including people like
Art Kavan, Wing Evans, Glenn Klein and Jerry Capps. What strikes me as
common in all of the "great ones" is their grace, humility and
willingness to share their knowledge with those willing to expend effort
themselves. At the same time they are not afraid to stand their ground
even if it means they must stand alone.
I live in N.E. Ohio with my wife of nearly 34 years and have two
daughters who are both now on their own, one,an advertising executive
and the other a medical insurance administration executive. In addition
to lapidary I enjoy raising tropical plants, tropical fish, astronomy,
painting, ceramics, and wood turning and model railroading. I also do
some work with electronics however, that is not set up presently pending
a move. Of course I don't have time for all of these at once however, I
rotate my activities to keep things interesting. However, faceting seems
to be a permanent hobby interest. My wife is also office manager and
also enjoys her own arts and craft projects as well as reading and history.
I look forward to receiving the list and hope I may be able to
contribute worthwhile information to it.
A big welcome Jim, We look forward to your contributions.

Last month I offered Riker mounts for sale, but maybe gave the
impression that you had to buy them all. If you are interested in just
1 or 2 that is ok. Sorry for the confusion!

From: "Gail Bumala" <firstname.lastname@example.org>
Before you put kerosene in a saw tub, just remember that sparks do fly
from rock and those saw blades! Antifreeze is a poison and some of the
favorite old oils are full of PCB's. I don't know about the pink
antifreeze Thurmond suggested. Use what's on the market in the rock
shops for safest results. For getting into cabbing, look up and check
out your local rock club. There you'll meet plenty of people with all
the knowledge and probably equipment and rough to help you learn the
basics. They're the friendliest people around. Gail
Propylene Glycol is a food grade antifreeze used for
winterizing RV water systems and used to be an ingredient in Dr. Pepper for years.
Ethylene glycol is a deadly toxin if injested. It forms needle like crystals in the liver
and will kill very painfully.

From: Dennis Davis <firstname.lastname@example.org>
"Personally I use pink RV antifreeze (not automotive,
bad stuff) for
my large saws and water based lubes such as crystal
cut or such in
smaller trim saws."
I have a 24" slab saw. Can the RV antifreeze be used
on this saw? Sure would cut down on the mess of using oil.
Hi Dennis, I am using it in my 18" and 20". I have not tried it in a 24" but
I know those who do use it. I can't comment on blade life with it vs oil though.
Clean up is sure nice though.

To Whom it may concern, I bought an old faceter at an auction with
a label saying B & I Manufacturing Co. , Burlington ,Wisconsin. The only
info. I've been able to find is that the faceters were made by two guys
named Carl Backland and Harris Ide and the business shut down about 25
to 30 years ago. Can you give me any further info.,including any
estimated values? Your cooperation in this matter will be greatly
appreciated. Sincerely, Joe Overberg.
