Does anyone know of comparison testing that has been done on
blades and/or sharpening ageents. I sell slabs on eBay and have
running almost continuously - every time it is necessary to purchase
another saw blade, I wonder if there have been any tests or comparison's
done in the past that I could consult as to the best type of blade
There are so many to choose from and if there hasn't been any
done, why don't one of the lapidary magazines take up the gauntlet?
they afraid of getting their advertisers upset? For that matter,
hasn't there been any comparisons done on slabbing saws? Comments,

Oil & water & dish soap
Excellent recommendation Don..... Clear dawn or Blue colored
dawn soap works
Personally, after much research, I would lean toward using a
"food grade" petroleum mineral oil... Less to no odor
and less problems for
you, the slabs and the planet overall, than other types of petroleum
Leaving slabs in the sun after washing them etc. etc...serves
remove oil odors and yet it will not remove any sizable amount
of the oil
itself... I have picked up slabs that sat in the desert sun for
years and the
slab was still slippery
I have been told the only way to remove most of the oil is to
heat the slabs
in an oven, outdoors of course - good ventilation is needed !
can't remember the temperature needed to literally cook / burn
the oils out
of the slabs..
Oil is not water soluble, which is why it is difficult, actually
d a r n
near impossible to get it out of any type of porous materials,
other than the
hardest of agates that have no other softer mixed matrixes...I
tried to get oils out of hard agates that have hard pores / holes
agate and NO LUCK AT ALL.. I'd have to oven bake the slabs to
get the oils
out of the holes
Myself, I have decided that I will be cutting in Water Only,
basically require 2 simple procedures......First purchase a good
is able to cut in water,,, MK has such a blade & up to 36"
...as do other
manufacturers....... Second, the saw and blade must be cleaned
after each days use, which is about a 30 to 60 minute job, MAX...
figure I'll save loads and loads of time, by NOT having to clean
single slab of any oil mess.....
Of course the blade life will be reduced by some small percentage,
still will last for years, as I am not a massive production cutter...
Subject: Continuous rim blades

From Issue #6" "Continuous Rim Saw Blades..
I was not aware that MK made an 18 inch Continuous Rim Blade..
Which model number of the MK blades ... ? 297 , 301 , 303 ....Are
you don't mean a sintered blade, which has a notched rim, or a
I think the NU-TEK brand of blades, with smart cut technology,
Continuous rims up to 16"..... and maybe 18" ?? ....
But I was under the
impression that MK stopped their continuous rim blades at 14",
due to some
type of cutting problems........? RnL "
You are correct that the MK blades from 16" through 36"
are segmented; only
the 4" through 14" are continuous rim. Nu-Tek or Advantage
blades (the same
thing, different names) are continuous through 16".

From: Charles Moon <email@example.com>
Alexandre Wolkonsky in 4/22/92 Designed a "PRINCESS LOOK-ALIKE"
Design - AW 9); Angles for Corundum; 61 facets; Crown = C1->C3;
Pavilaion = P1->P5; CULET ANGLE = 41 degrees
Shape = Square
Table Area = 29.6 %
T/W = .6480
C/W = .1502
P/W = .5821
H/W = .7523
Would have sent the angles, but not sure about the copyright
requirements. The given information should be enough to whet your
faceting appetite,that is,if interested. It is my understanding
Mr. Wolkonsky was one of the first, if not the first, to attempt
reproducing the the Original Princess design. THERE IS A COLLECTION
OF THE WOLKONSKY DESIGNS (31 one in number)THAT USED TO BE AVAILABLE
THROUGH THE USFG??? I WILL LOOK INTO THE MATTER AND POST THE
INFORMATION. BTW, The Collection was computed by Fred Van Sant

I found that duplicating a printed design in GemCad to be the
best way to
learn the program. I usually need a *.gem file anyway because
I play a lot
with the crowns to bring up the dispersion for the garnets I'm
cutting. Pick any printed design and start with a clean slate.

Jubilee Project Update Regarding Cutting Instructions:
Because "Classic I" is one of Jeff's published designs,
he doesn't want
to publish full details on the web. But he has done a step-by-step
guide for us on how to cut the design, which you can find on the
However, in order to use this guide, you'll need the list of
indexes and angles. So, if you are cutting a stone for the Jubilee
project, please e-mail me and I will send you the details separately.
Subject: Protractor accuracy
Date: Fri, 15 Nov 2002 20:50:45 EST
This was my approach....not as fancy or time consuming as cutting
retroreflector and using laser lights etc, but it got me pretty
Tell me if I am off base.
I dopped a decent size stone ( about 10 mm ) and set protractor
at 45 deg.
and cut a good size facet at index 96. Size is unimportant. Then
to the 48 index and cut another facet to the same depth. Obviously,it
very important that both are cut to exactly the same depth. I
used a 600 lap
if I recall correctly.
Remove dop from quill and take to your nearest hardware store
and find a
machinist's square. Hold dopped stone in the 90 deg. right angle
the square. and hold up to a light background. If you have your
machinist's square, more power to you. If you observe any "daylight"
see whether you are plus or minus a little in the 90 deg. opening.
home and fine tune your equipment and do it again. An optical
many inspection labs have would be even better, but since I am
now retired I
really don't want to drive 200 miles round trip to my old place
to ask them to do a "government" job for me.
The second cycle did it for me. I'm happy that at 45 deg. I am
to 90 deg. when they are added together.. Therefore, at normal
etc I'm confident I'm OK.
I have a Vargas Fac-A-Gem machine with a separate handpiece....not
Raytech. My slight adjustment was to move ( bend) the protractor
indicating arm a small fraction of a degree.
I'd be glad to answer any questions as long as they don't involve
and staff machines. I love the separate hand piece approach to

TODAY'S FUNNY ~
A clergyman walking down a country lane and sees a young farmer
struggling to load hay back onto a cart after it had fallen off.
"You look hot, my son," said the cleric. "why
don't you rest
a moment, and I'll give you a hand."
"No thanks," said the young man.
"My father wouldn't like it."
"Don't be silly," the minister said.
"Everyone is entitled to a break. Come and have a drink
Again the young man protested that his father would be upset.
Losing his patience, the clergyman said, "Your father must
real slave driver. Tell me where I can find him and I'll give
piece of my mind!"
"Well," replied the young farmer, "he's under
the load of hay."
REFLECTIONS AND TIDBITS:
" Use the talents you possess;
For the woods would be very silent,
If no birds sang except for the very best."

This post is simply a reminder that in 2003 the USFG will host
first National and International Faceting Competition. It is called
the North American Faceting Challenge -- 'NAFC.' Since the designs
and rules were first published in the 2001 September Issue of
USFG's Newsletter, and since they have not been published since
some of you, who are most capable - skill-wise, may not
know about the competition, and some of you may have forgotten.
"NAFC" is an OPEN Competition. Please note: The designs
can be downloaded at <http://www.usfacetersguild.org/events.shtml>.
The closing date is June 20th, 2003; the amount of time between
present date and June 20th, 2003 should be enough for all Master
cutters to cut the two required designs -- Fred Van Sant's "Four
Star," and Charles Covill's "Wind Wheel No. 2."
