A question of FACETING SPEED
Dyer, as an Ultra Tec representative, is an "activist" - not shy with
opinions and recommendations. More than a year ago, John talked about
wanting faster vertical adjusting - a fast leadscrew (as a professional,
speed is important to him). He understood that we needed to be careful,
to be sure that vertical precision is retained.
We experimented, and
settled on a double speed leadscrew - that is, a full rotation of the
Vertical Knob advances 4 mm instead of the "standard" 2 mm. We sent it
to John for its "real-world" test -- He tested it. He declared it a
success, and had his machines converted.

after, when Andy Gulij was doing the initial Fantasy testing, we gave
him a fast leadscrew Mast to use -- and there was no way Andy was going
to give it back. He loves it.
Well, the word is out -- people are asking about it. We've delayed
because, doing it "properly" would mean changing the Vertical Scale (a
problem - here we are, trying to hold prices steady). But, if you are
someone who wants this, here's the story:

A FAST LEADSCREW
immediate effect a FAST LEADSCREW CAN be installed into your machine.
You need to understand that the existing Vertical Knob scale remains -
and that increments of the Vertical Scale, instead of representing .020
mm, with the fast Leadscrew, will represent .040 mm. For most faceters
that's a non-problem. John Dyer reports that repeatability is not at all
The Leadscrew, and the Mast, looks exactly the same - it just advances
twice as fast.
If you are purchasing a new machine - the price of a Fast Leadscrew
installation is an added $80.
If you want to change your existing Mast into a Fast Leadscrew version -
the price is $385 (includes complete disassembly, rebuilding the Riser
Block and installing new follower bushings - reassembly with new
leadscrew - replacement of Yoke Bearings (if indicated) -- adjustment
(Note: Early machines - we are not sure of the exact date - we think
pre-1980 - might need replacement of the Upper Bearing Support. If so,
the color of the replacement part would be black, and the price of doing
the changeover becomes $460. We would advise you of this condition and
get your OK before proceeding).
HAPPY BIRTHDAY DAD
DIGITAL ANGLE DIAL is two years old. It's a good time to look at its
reliability record. Before we announced DAD's availability, we tested
and tested, but there's nothing like real world results -- and, on DAD's
second birthday, the two year record is exceptionally good!
There has been only one unit that needed replacement - out of hundreds
in the field (and, in accordance with our plan, that replacement was
made immediately, with the reserve DAD on the shelf - there to assure
minimum down time).
User compliments from people who converted to the DAD from their old
analog Angle Dial continue to come in. It's tempting to quote some - but
you've seen them before.

John Wichman's interesting works:
Wichman called in, to order an Index Gear, and during the conversation
we learned that he does unusual and interesting "faceting" - for display
- none of it "jewelry". John was kind enough to send in pictures, and
tell us about his methods - and here, we pass it along:
Wichman lives in Hemet, California - almost in the desert - about
halfway between LA and San Diego. John is a long time faceter - but he's
certainly not a "typical" faceter -- that is to say, you won't find any
standard instructions for his interesting creations.
equipment is pretty standard, but as you can see, he's done some
modifying of the Base. On the Mast, he uses a 2" Base - he needs the
extra height for the very large pieces he works on He also uses the
Oscillator, with a pretty hefty weight, for the large sized facets that
are common in his work - in handling the unavoidably long polish times,
the Oscillator/weight combination applies a steady even pressure, and of
course, does the work tirelessly.
does use an array of special dops that he's made for the unique shapes.
For any of you interested in the techniques he used, he has provided us
with descriptions - we've put them in the Library.
More on John Wichman's Designs
few months ago we told you about Stephen's moving from New York to
There's probably more than a little "culture shock" involved. Arizona is
not exactly New York.
His view today, in Sedona, looking out through the back yard (see it on
the right), is nothing like the views in New York.
course, Stephen is not a stranger to the West. He had visited Tucson
often, taking part in faceting competitions, and winning more than a few
awards. Of course, set up in his faceting workshop - New York, Arizona ,
or wherever - Stephen continues to be the superb faceting craftsman that
he's proven to be.
Recently, on his Facebook page, Stephan published
pictures of his work -- in a Facebook photo album titled "Memorable
Stones Cut By Me"
