To all of you in the Ultra Tec family.
When It started out in 1981, its name was The Ultra Tec
Newsletter - but it soon got to be called The SomeTimes. The name
stuck-maybe because we maintain what has become a tradition of being
a little late with it -- sometimes. This is the April issue - it
says so. But it's so close to May, that maybe we'll call it
April-May. Why not?
FANTASY & CONCAVE MACHINES
Here are a group of Fantasy machines in Assembly - wrapping up.
That's Robert Mendoza overseeing final testing.
The several machines that had been "out there" in the World are
now joined by the ones in this photo, and we expect to report
feedback in our next SomeTimes. We of course did considerable
prototype testing - including testing by professional cutter Andy
Gulij (who lead us to several design refinements), and we performed
"life tests" - long time steady operation - with "no fail" results.
All of that, combined with the intense interest we found at the
Tucson introduction, makes us optimistic about these new machines.
If you made a list of the first 10 subjects of concern to faceters -
amateurs and professionals alike - the number 1 subject would be
"polishing". For that matter, probably numbers 2, 3, and 4, would
also be polishing. I think, if you ask 10 faceters, you'll get 7
"best ways" -- none of them "wrong", and none of them "the
absolutely right way" but all of them worth considering. You will
find a technique that feels best and works best for you - but even
when you think you've got "IT", keep your antenna working.
Here's a bit of advice we gleaned from Cambridge Professor Brad
Amos - advice from him to a local faceter. Properly, under the
heading of "one man's opinion" this one man is Dr. Brad Amos.
"I use the 'Batt' lap with 50K diamond. It polishes almost
everything except the very softest stones such as apatite, for which
I use a tin lap. I may as well tell you the procedure now.
Get some odourless and harmless non-drying oil. I use oil
designed for woodwind musical instruments. Remove the rubber drip
tray from the Ultra Tec and clean everything (including under
fingernails) to remove grit from previous stages of grinding of the
stone. Put the Batt into position without the drip tray and add no
water at any stage of the polishing. (Water makes diamond dust form
into hard agglomerations which produce large scratches, because
diamond is hydrophobic).
Anoint the lap with three small drops of oil, add no more than a
cubic millimetre of diamond dust and work this over the surface with
fingertips until the entire lap is grey. Some people press the
diamond in with a large flat piece of synthetic corundum: I find
this unnecessary. A small facet should polish within 30 sec if
appropriate prepolish has been given. To check the polish you need
to be very fussy. Clean off all the oily diamond residue (I use
chamois leather but a microfibre cloth from Tesco is just as good)
and look hard with the 10x lens and with the intense light from a
fibre optic not quite reflecting into your eye. You will then see
defects such as deep fractures from earlier stages, as bright dots
of light against a dark background. You have to keep polishing until
they have all gone."
Yes, "one man's opinion" - a scholarly, scientific opinion. Other
opinions most welcome.
NEW ZEALANDERS - ATTENTION!
Sean Fennessy at Worldwide Gems in Wellington is offering Faceting
Classes. Saturday or Sunday Classes are limited to only 3 or 4
students, so there's plenty of personal attention. Each person will
have a current Ultra Tec faceting machine to use. It's a full
day-going through each step of the faceting process. At the end, the
knowledge is yours, as is your very own faceted stone that you will
be pleased to show.
To contact Sean, call 04-939-7949 or email firstname.lastname@example.org
