Winter 1995 / Start of 96 Edition
Dear Ultra Tec Cousin,
This was almost a 1995 newsletter. I almost had it ready in November - it
even included a "Merry Christmas!". But, "almost",
only counts in Horseshoes - or doesn't count in Horseshoes - I forget
which (now that I think about it, it's not almost" in Horseshoes,
it's "close" - whatever). This introduction helps explain,
however, why the typically dated Ultra Tec "SomeTimes" is even
more dated this time.
It may be even too late for HAPPY NEW YEAR - but there it is -
without the '!', since it's so late.
If the Some-Times had gotten out in '95, it would had sent shockwaves
through the publishing world - so perhaps it's just as well. Think about
this - we've got a shot at a second newsletter this year. Guinness! Hold
the presses! (actually - it wouldn't be a record - it would only tie the
OK - enough chit-chat. This is serious - this is the Ultra Tec SomeTimes.
Incidentally - why don 't we try (we used to - try) for more frequent
newsletters? There's a good reason: There isn't really a need. These days
we have the Faceters Guilds and their newsletters - with very good,
practical advice, new designs...the whole works. The SomeTimes provides
information that we think is of special interest to our Ultra Tec cousins.
LOS ANGELES COUNTY FAIR. During September, we had an Ultra Tec
faceting machine in operation at the L.A. Fair - at the Gems and Minerals
exhibit. This is probably the biggest annual fair in the Country - bigger
than any State Fair we've ever seen. The Gem and Mineral display, for the
past years, has been coordinated by Arlene Billheimer of the
Pasadena Gem and Mineral Club - always cheerful and optimistic, Arlene's a
super organizer and does an excellent job - and we tip our hat to her (no,
that's not funny hat she's wearing in the photo - that's a California palm
tree in the background).
Demonstrating on the Ultra Tec stand were faceters Gail Paulson,
Todd Neikirk, and Henry Debick. Henry entertained the onlookers
by completing a "Butterfly Cut" (a design by Don Clark)
as they watched and learned about faceting. It's no longer a surprise that
most people visiting the Fair have no idea of how faceting is done and
certainly no idea that they themselves can do it. So it's a good place to
"get out the message". Ultra Tec gives thanks to all the
people who helped out - the Gem and Mineral displays and demonstrations
are a high point for visitors to the Fair.
FACETERS GUILD of SOUTHERN CALIFORNIA. Also in September, the
Southern California Guild had their annual show (their 16th! which I find
a little mind-boggling). It was in Costa Mesa, just a few miles from the
Ultra Tec factory. Robert Rubin and Gus Munoz represented
Ultra Tec there - and reported that the usual fine job was performed by
the Southern California group - and special recognition and thanks are due
to the show's co-chairs Bob Cardon and Clare Gagnon.
Rather than a long report on the September show, I'd like to use the space
to alert you to something special that the Southern California Guild has
in store for 1996:
A FACETERS SEMINAR-_ connected with the 1996 Show of the National
Federation of Mineralogical Societies. It will be in Riverside California,
on August 9-10-11 mark your new 1996 calendar! The seminar is under the
direction of Glenn Klein (in the photo), an award-winning faceter -
thoughtful and : thorough-planning - who I am sure will deliver an
"award-winning seminar" (Glenn should need no introduction to
readers of the Ultra Tec Some Times). A "seminar" should not be
confused with a "show" (look back at my comments about the
Northwest Seminar in the previous newsletter).
This Seminar will be 3 days about faceting - interesting speakers -
plenty of time to exchange information and ideas with others - a chance to
make faceting friends - plenty of fun - and a chance to take in the
exhibits of the National Show. You will leave the Seminar a smarter and

FACETING TIPS, IDEAS, and HOW-TO's:
ABOUT KEYED DOPS - OVER-RIDING THE KEY - AND STILL HAVING IT
It's well over three years since we went to a keyed dop system. The
reaction has been very positive - but there were a few "voices of
discontent". They complained that although they could over-ride the
key and rotate a dop freely, they could not then remove the dopped stone
and later re-insert it to the same position. For instance, someone said he
likes to take the stone out to work on the table and afterwards reinsert
the stone to touch up the crown facets - and if he's overridden the key,
it's a hassle - it would be nice to have a "setable key".
Well, you do have a "setable key" - here's how:
OK - you have a stone dopped, and you want to rotate it freely to some
special position, and then key it in that position - so that you can
remove and later re-insert the dopped stone to the same place. Here's what
|1. Insert the dop
so that the dop seats fully and firmly-engaging the cross-pin in the
Spindle ("keying it").
2. Set the Index Gear to the 0 position - the Detent is engaged with the 0
on the Index Gear. Now, loosen the set screw that holds the Index Gear to
the Spindle, allowing the Spindle to slip - to rotate freely - within the
3. Now you can rotate the spindle freely until you have the stone lined up
the way you want it. Then, retighten the setscrew on the Index Gear -
simple (incidentally, the setscrew has a brass tip which holds tightly
without harming the steel spindle).
4. OK - you've done it - you've set a "special" keyed position.
You can now remove the dop if you wish and then reinsert it, to its
special keyed position.
Before you do your next stone, reset the standard 0-cross-pin key
position, by using the calibration bar (that little "hammer").
It's all fast and easy.
You don't always have to set a keyed "special position" - if you
have a long thin stone - like a tourmaline - it's easy to reset the
stone's radial position by lining up the stone itself on the lap - so, in
those cases, you can use the "pull-forward" over-ride of the

DOPPING WITH SUPER GLUE. I' ve been using super glue (specifically,
Loctite 404) for a number of years. The only thing I didn't like about it
was that upon transferring into a cavity dop, I had to wait longer than I
liked for the bond to be strong enough to proceed. The problem was that
there was insufficient air to make the glue set up quickly and
thoroughly-the stone was acting like a "cork in the bottle",
slowing down the hardening process, since the only air getting at the glue
was what sneaked by the facets.
Somebody suggested (I don't remember who it was - but I know there will
be a number of claimants) that it would be good to drill a side hole into
the cavity dop into the lower clearance portion - allowing air to get in
behind the stone. A hole on one side - OK, a hole through - better. See
|I've tried it
several times now, and it works very well. It also helps after faceting is
complete, in removing the stone - I use the boil-it-in-water technique -
and the hole allows the water behind the stone (just like it let the air
It's tempting to just add that hole on regular production - but before we
do, we want to make sure it doesn't cause a problem with other dopping
techniques, like wax, for example.
POLISHING WITH...NOTHING BUT WATER?
That was the subject of an article by Glenn Klein in
"Angles", newsletter of the Faceters Guild of Southern Cal. Yes,
he said he polishes with just plain water - no added polishing agent. He
assumes it's the sub-micron stuff (whatever) that's in the water - and he
allows that it's a very slow process (he said "I'm the slowest
faceter in the West-and probably the East, too" - as a competition
cutter, he takes many hours on a stone). But he says plain water does the
One of my neighbors is a water engineer - and I spoke to him about it. I
soon became educated. Water is not a dry subject.
Among the things I learned was that with rare exception our tap water is
not filtered very finely - it contains occasional particles of 10 to 12
microns or more (that's like the particle size on a 1200 mesh lap!), and
many in the 3-9 micron range. Considering that we like to polish with
Cerium Oxide at 1 micron (which breaks down to smaller particles), or
Aluminum Oxide at 0.5 microns, you can see that using tap water represents
a risk (depending on where you live, more or less of a risk). Glenn did
write that sometimes a scratch would "suddenly appear".
Now, I'm not trying to debunk the idea of polishing with plain water, but
I guess that Glenn lives in an area with relatively clean water. I've
heard from quite a few faceters, however, in other parts of the USA, who
have complained about "scratchy water", and they've had to use
filtered or store-bought water. My general advice is: if you suspect your
water is "scratchy", it probably is, and you need to get
filtered water. If you do have filtered water in your kitchen (many people
do), don't be lazy - when it's time to refill your drip tank, make that
trip to the kitchen for the filtered water.
And, if you're in a mood (a long-lasting mood) to try Glenn's
prescription, try it - and let us know how it goes.
Anyhow, Glenn - years back, I was faceting a piece of Apatite. It's hard
to polish - it's soft, and it flakes - and when I asked an old timer what
to do, he said "Whet your Apatite".
NEW THING - A "Stop Indicator" - a device that signals
contact with the stop. Is this similar to the "Down Indicator
Light"(the "DIL")? It is. But, this Stop Indicator features
a buzzer (which is optionally-on), and several other improvements:
|The unit is in a small
(2"X 2"X 4") box that can be set conveniently in-line with
the work, so you don't have to look back at the Mast (as you do with the
It uses a standard 110V outlet - no worry about batteries
There's no "hardware" to hang onto the machine - only the wires
connect to the Mast - easier to maintain - reliable.
The Buzzer feature is for speed - work until you hear a "beep"
and then index to the next position - and move along very fast. The buzzer
is in the box, so that its sound is muted enough not to drive one's spouse
crazy - but there is a control that lets you increase sound level when
you're working on a coarse lap. And there's a switch to turn off the
buzzer, when you want to.
Would I get one of these if I already had a DIL? Well - I did (of course
at my special employee price). It's nicer than the DIL-
