OK, the secret's out here.  I had posted some time ago on the other list
that I was making a limited amount of these for sale.  I was inundated with
so many orders I had to shut the waiting list off before I could even post
about it here, at which point I was afraid to. I also did not want to
appear to be self-promoting, but since there are none for sale for some
time in the future, it does not matter, now.
Basically, I had a very persuasive individual pester me sufficiently by
e-mail that I sold him a prototype.  He published a lot of very
complimentary things about it, which opened the floodgates.  Like the story
about the "Sorcerer's Apprentice", it promptly got out of hand and I found
myself booked up to 2005 before I could shut the list down.
Oh well.  I had not REALLY intended to retire, anyway.
  Glad to make something people like!  It's better than manufacturing
things like colonoscopes.

Well I am glad to see there are others out there that teach their children
this art....... My boy has been faceting since 10 and is now 13 and still
loves it. He has not found women and beer yet....T>G>

It is hard to get a bunch of people together to get them interested enough.
Then they find out these DAM machines are so expensive and they don't want
to invest in another hobby that might end up at a yard sale. I initially was
introduced to this at the Sprinfield Museum of Science, Sprinfield Mass.
Conn. Valley Mineral Club in 1963 .....BUT .....all the rest goes with
it.......

It seems until we are tenured in the art of rewarding ourselves at an older
age we find other things more important.......Its kind of  like that old
expression.....
Geeze if I knew I was gonna live so long I would have taken better care of
myself..........................I just hope this sticks with my son Joe, he
loves his mining and we love to be out in the woods
together.............What better a Christmas present than a son who wants to
spend time with his old man........!

My best to all of you,  thanks for all the great information and
posts.........I enjoy them....

Oh.........I just bought a Stanley Perham /  6 piece rock collection on
Ebay..............Stanley is the father of all Maine's mineral sales and
dealers.....This collection is from 1938........................what a
find.....

Hi Peter,  Rain? Forgotten what it looks like. We had .03" of dust Monday
though during an all day sandstorm. Send us some of that rain.

Hi Thurmond!
I have a couple of things for the next digest.
First, some advice to others using vibrating flat laps: even great quality
moss agate doesn't respond well to this treatment. We just made bookends
for one of our daughters out of prime quality moss agate from near Alpine,
TX. When we got to the polishing stage we discovered that a central pocket
had become hollowed out on both bookends during the 600 grit semi-polish
stage. In retrospect, this was a logical thing to happen, but I didn't
anticipate the accumulation of grit which caused it.
Second, I'm selling four new condition, unused Lortone EX83 sanding drums.
These are tapped for 3/4" arbors, and take 25 1/8" sanding belts. We are
asking $20 each, or all four for $65. Plus shipping in either case.
Keep up the good work, and have a wonderful holiday!

From: "Rich" <richtherm@bluemarble.net>

Hi Doug,

Don't mean to be repetitive, but Thurmond is right.  Ruby rods have a
pink tint to them and YAG (usually ND:YAG or Neodymium Yttrium Aluminum
Garnet) will be clear or in larger sizes have a yellowish tint to them. 
I can be wrong, but a simple scratch test using a sharp edge on outside
of the rod with a piece of garnet and corundum should tell you.  Don't
scratch test the ends though, you may still have coatings on the rod,
but they will be an AR coating (Anti-Reflection) added for .694 micron
wavelength and it will be almost invisible except at an angle.  This
coating might scratch giving a false impression of hardness.  Use
standard angles and polishing procedures for corundum.

Another note, the AR coatings are on good, but, they make adhesion a
problem with wax or glue.  If using the ends as the table area make sure
you rough them up good to get the coatings off or a zinger might get
you.

Some of the prettiest stones I have ever cut has come from both Ruby,
ND: YAG and ND:glass laser rods I've picked up or saved from college and
work.  I'm still looking for that alexandrite rod from the medical
industry,,,,,  any skin doctors done removing tattoos and unwanted
hair??????

Hello All

Boy, am I confused???!!! I have had many responses for help, both on and
off line. I have been told it is Optical Laser Glass, Yag and Ruby, most
claiming Ruby. Here is a web site that has a picture of a Ruby Rod that
looks EXACTLY like it. 
http://www.laboratoryoptical.com/materialsproducts.html

I'll take it to Washington University, St. Louis, Missouri, and ask them
to identify it. I'll let you know what I find out.

I also want to give thanks to all of you that have so willingly given of
your time to help me. You are a great group of people!

Thurmond (and list?),

Digests developed in traditional mailing groups because at times of high
volume people didn't want to deal with that many individual emails. The
traditional digest is mailed either at the end of the day (if there were
any posts), or whenever the number of accumulated posts during the day
reached a certain number. If the volume of posts is high you get one at
say 3 pm, and a second one at the end of the day. If the volume is low
you get one at the end of the day. If there are no posts you get no
digest (or maybe an empty digest).

Most mailing list packages can be configured to produce individual or
digest type mailings by subscriber option (or constrained by the
administrator). Most list packages also allow for open (automatically
distributed) or moderated lists (only approved submissions distributed).
All you should need to do to produce a mailing is review the postings,
and whatever you approve will go out automatically at the end of the
day.

Another advantage of email groups is that they disseminate knowledge and
questions with relatively little delay, but allow participants to
process the information at their own (possibly delayed) rate. By placing
a minumum number of posts for publication you are introducing delay into
the distribution, and weakening the value of the list to its members.

Personally I most appreciated your well moderated list on a daily basis.
I also appreciate the effort needed to maintain and moderate any list
(and understand that a small and big list have roughly the same effort
because of the basic overhead of any individual 'mailing'), and your
desire to move to a weekly instead of daily schedule.

OK, move to a weekly digest; I agree the current volume seems to warrent
it. Don't give up! But please send out a digest anytime you have (1 or)
3 to 7 (or 10, pick a number; I suggest a low one) unpublished posts so
that when a hot topic pops up the digest stays current.

You have had a great list and I expect it to continue and thrive; I hope
my opinions help you find a publication formula that makes that happen.

Hi Kreigh,  I tried automated list in the beginning but did not like the "Look"
of the publication produced. When a person would post in any format other
than plain text (such as HTML, Default Microsoft Setting) the messages were
very hard to read and spoiled the formatted look of each digest. Same issue with
attachments and / or those who just hit the reply button and neglect to remove
the previous ENTIRE digest from their new post. The only option I found was to
collect the post automatically then hand edit and assemble them into a pre-built
template. The list is then sent using a different program.
I do not like commercial groups (yahoo and others) although I belong to several
because they tend to abuse personal information and besiege you with advertisements.

Subject: WD40 use with BATT laps
Date: Thu, 18 Dec 2003 05:08:01 EST
To: faceters@caprock-spur.com
From: TheCuttingWorks@cs.com

To all,
For several months now I have converted to using WD40 to clean all of my BATT
laps [when the swarf build up begins to cause scratching or when the
polishing speed slows down due to a reduced amount of charge].

I usually average working on 4 to 6 stones per day and the species varies
greatly depending on customer requests - though most of my work is in corundum &
emeralds.

My question to the List is..... for those of you who clean your laps with
WD40, do you find that you must clean them much more often than prior to using
WD40?

Diamond Sanding Belts

Looking for any & ALL factual input and especially any opinions, as to which
Diamond belts are the best.

The specific topics I need are manufacturers, suppliers, prices, best for the
buck, diamond particle longevity, belt backing longevity, resin bond vrs
metal bond, which belts cut agate and hard materials the best. Which belts can
take hard use the best.....

Are certain belts better in the LOW grit ranges 60 80 100 and then are other
belts / manufacturers better in the MID ranges 220 400 600 and up.

Or can it possibly be for instance that  3M is good for the LOW - 60 80 100,
then a brand like Eastwind for the MID range is OK and then back to 3M for
1,200 3,000 10,000 but then after that, possibly going on to another manufacturer
for the VERY HIGH ranges of 50,000 100,000.

Thanks for any & all facts and opinions and theories.

Are there any fee to dig areas in western B.C.? I heard they found some
new mineral and was wondering if anyone has heard of areas that might
open when the winter is over.

Ref input from Frank Norman of 5 Dec
<I seek cutting instructions for briolettes, preferably for gemcad.  Any

advice, or the location of cutting instructions, such as books, or web
sites would be appreciated.>
If you can access Datavue 2 and type Briolette in the Name section you
get five briolette designs. If not, let me know and I shall extract them
as Gemcad files and send them to you direct. Also in "Faceting for
Amateurs" by Vargas, general cutting instructions are given for
Brilliant Briolette on Page 117, Multifacet Briolette on Page 118 and
Step Briolette on Page 168 (these Page numbers refer to the 1969 =
edition).

TODAY'S FUNNY ~

Weapons of Math Instruction

At New York's Kennedy airport today, an individual  later discovered to
be a public school teacher was arrested trying to  board a flight  while
in possession of a ruler, a protractor, a setsquare,  a slide rule, and a
calculator. At a morning press conference, Attorney general  John
Ashcroft said he  believes the man is a member of the notorious  al-gebra
movement. He is  being charged by the FBI with carrying weapons of 
math instruction.

"Al-gebra is a fearsome cult," Ashcroft said.  "They desire average
solutions by means and extremes, and sometimes go  off on tangents in a
search of absolute value. They use secret code names  like "x" and "y"
and refer to themselves as "unknowns", but we have  determined they   belong
to a  common denominator of the axis of medieval with coordinates  in every
country. "As the Greek philanderer Isosceles used to say,  there are 3
sides to  every triangle," Ashcroft declared.

When asked to comment on the arrest, President  Bush said, "If God had
wanted us to have better weapons of math  instruction, He would have
given us more fingers and toes. "I am gratified that our government has given
us a  sine that it is intent on protracting us from these math-dogs who  are willing to
disintegrate us with calculus disregard. Murky  statisticians love to
inflict plane on every sphere of influence," the  President said, adding:
"Under the circumferences, we must differentiate  their root,  make our
point, and draw the line."

President Bush warned, "These weapons of math  instruction have the
potential to decimal everything in their math on a  scalene never before
seen unless we become exponents of a Higher Power  and begin to
factor-in random facts of vertex."
Attorney General Ashcroft said, "As our Great  Leader would say, read my
ellipse. Here is one principle he is uncertainty  of: though they  continue
to multiply, their days are numbered as the  hypotenuse tightens  around
their necks."
