One of the best ways to orient labradorite is to place your rough stone
against the edge of your bench with a strong light over it below eye level.
Roll the stone until you get the best play of color. Now, mark the rough
with a heavy marker paralllel to the table top. Next rotate the stone 90
degrees and repeat the proceedure and mark the stone again with the two
lines joining. You can now saw and get equal quality slabs on each slice.
This also works for tigereye.

Hi All,

Thurmond, speaking of Spectrolite does anyone know where to get ahold of some rough Spectro
without paying a fortune??? I spent an hour on the net last night searching and the best I could
find was to go to Quartzite but I doubt if we will make it this year...If anyone out there has
some spectro and wants to sell, or trade, as I have a huge pile of Old Biggs w/blues I can trade
some choice pieces, just let me know.........Thanks,

Dale Rhode.....Rhodes Cabbin And Gems

Hi Dale, I purchased my spectrolite last April at a show from
The Unconvential Lapadirist. I don't remember the price.

Hi All,

While I have no information to impart about quickly orienting schiller sunstones other than the
normal use of an overhead light source and marking pens, I do have a related question.

When cutting schiller stones I have a hard time determining where the copper platelets are that
produce the schiller effect. The orientation of the schiller is not in question, but how deep
or shallow the plane of copper platelets is my concern. This has an impact on the size of the
finished stone. After the orientation is determined, the stone is ground over and under the
schiller layer. If I could mark the side of the stone where the schiller layer is located I
would have an indication of how much rough could come off the top and/or bottom. Not knowing
where that layer is risks the same problem as cutting right through the plane of color on an
opal.

Some stones have enough copper plates to determine their location. However, schiller that is
not as strong is harder to assess.

Any advice?

I cut for color. I will sacrifice weight to get the best color. I try to
buy the rough so the best color gives the highest yield, but if it is not
possible I'll cut for color.

From: "Peter L. Herschman, M.D." <herschm@golden.net>

Dear Jill and Ray:

For several years I used a Raytech and had a similar problem. Mine stemmed
from the platen under the handpiece proving slightly wobbly due to
misalignment. Discovered by Al Manestar who was examining the machine when I
could find nothing wrong, he repaired it with some epoxy.

In my searches for problems, I examined my transfer jig, using two perfectly
straight, drill rods (quarter-inch as were my dops) machined to exact
specifications with a flat surface at 90 degrees at their ends. Perfect
alignment of the jig was found when I could rub my fingers along the rod
ends as they touched with no groove or ridge. This was another of Al's
discoveries.

Still further research moved to my "cheater" on the handpiece, and the
little feet of the handpiece tripod which need to be at the same level, much
as Thurmond wrote.

A loose tightening ring or uneven lap can also cause similar effects. I
suspect the consistency of the crown table facet dislocation leads toward a
platen or handpiece problem.

I hope my own self-doubts as a result of the difficulty finding the
misalignment in my own machine are not repeated with the two of you. I was
very discouraged until Al discovered the mistake was in the machine, not my
cutting.

Best wishes,

Peter L. Herschman, M.D.

Jill St. Michael,

Assuming that your laps are flat the only thing that can cause the
problem that you are having is a misalignment somewhere. I've had
two things cause it for me. One was a poor alignment during
transfer. This can be checked by chucking up the dop that is on the
pavilion in a drill motor while the other dop is still attached and spin
it. If there is a bad alignment it will show up by wobbling. The
other time, it turned out to be the collet on the hand piece. It had
become egg shaped and when I tightened it up there was a bad alignment.
I found this by putting a gob of children's modeling clay on my master
lap, into which stuck a large darning needle in the vertical position.
I set the hand piece at 90 degrees with your doped stone in place and
lowered it to almost touching the needle, then slowly rotated the hand
piece observing the gab between the point of the needle and the girdle
of the stone. Now there will be a little difference between the flats
and the points of the girdle but by careful observation you will be able
to tell if the stone is true. I'm sorry I couldn't be of more help.

Hello Jill,

When I first started faceting I too tried cutting the table last
and was very discouraged with the results. After very few stones
I tried cutting and polishing the table first. Needless to say
in the last 30 yrs I have not bothered attempting to cut
'backwards' again.

I have a list of the many advantages if you are interested, I
have yet to hear a valid argument against this approach.

Tony.

Hi Jill,

Have I been in your shoes!! I cut on a Raytech for 4 years before moving on
to a Facetron. During this period, I too fought the same girdle problem and
could never figure it out.... until I purchased a new transfer jig. Now I
only have to make very minor adjustments if at all. If you are using the
Raytech transfer jig, I highly recommend you consider replacing it as in my
case, this was my problem. Suggest you query the group and see what the
general opinion is of the Raytech transfer equipment. Maybe you and I are
the only ones with this problem. Sure.

Good luck!
Regards,
Mike

To: lapidary@caprock-spur.com (LapidaryArtsDigest)
From: Don Rogers <Don@Campbell-gemstones.com>

I have cut on a Raytech for about eight years now, and for the last two, I
have been working on ways to improve the experience. I wrote an article on
machine alignment which was in this years Lapidary Journal Buyers Guide
issue. I also have a site for alignment procedures for the Raytech, and a
partially completed section on my RayDial modification.
http://www.campbell-gemstones.com/RayTech/ for the alignment article. Its
about 7 pages long so keep using the next button
http://www.campbell-gemstones.com/raydial/ This is still a very much in
the works piece. The last html file gives some of the issues with the raytech.

Thurmond's comment about the platform to lap alignment is
correct. However, it is not the first thing to make adjustments for.

The heart of any faceting machine is the lap. Every movement or adjustment
on the machine is in reference to the lap. Now the lap path is determined
first by the spindle, so this is the starting place for resolving alignment
problems. Your spindle first of all needs to be smooth and it needs to be
tight. By this, I mean no sloppy bearings are allowed, but you don't want
it so tight that you can't easily turn it by hand. To check out the
spindle properly, you need to set up dial indicators, and jack screws to
stress the shaft and check for movement. The next best thing is to mount a
lap and then grab it by the ears and rock side to side, up and down. back
and forth, etc. If there is any slop, in the bearings you should feel a
slight clunk. Any movement that you can feel needs to be fixed. This test
should be performed after the machine has been running for at least an hour
to get things warmed up.

After you have determined that the spindle is tight and running true and
quite, then you need to check the platen. You will need a ceramic disk,
and a dial indicator to do this. A ceramic is less likely to have any
wobble built in, and you can't bend it or put dents in it to cause
problems. Just make sure it is clean and doesn't have any gunk on the hub
area. If you have an indicated wobble, you need to have the platen
trued. The most accurate way to do this is to re-machine the surface while
it is spinning in its own bearings. Polymetric makes a platen and lap
truing tool. It is not cheep, but for a club, it would be a good
investment. It can be mounted on almost any faceting machine. For the
Raytech, you will need to drill and tap one hole in the base plate. If you
don't have access to this tool, or a machine shop who can do the setup and
cut, then you may need to send your machine in to get this resolved. The
bottom line here is that you must be able to spin a known true lap with
"ZERO" wobble. If you can't get to this point, any adjustments you make to
your machine will just be Kentucky windage.

After the spindle is correct, the next step is to make sure the platform or
mast is in alignment with the spindle. For our discussions here, I am only
going to talk about the Raytech. Again, before doing any check of platform
alignment, you need to make sure it is not wobbling. Again the dial
indicator comes into play. Set it up and check that the platform is
spinning true. Unfortunatly few of them are dead on, but if they have less
than 0.002" wobble, and is not a ripple with more than one dip per
revolution, then you can live with it, but you need to know where it is.

Now, again using the dial indicator, check the platform to lap
alignment. You should have less than 0.001" of difference when swinging
the dial from full front to full back across the lap. You also want to
check if your platform it tipped to or away from the lap by sliding the
dial from the spindle nut to the edge of the lap. Again you should have no
variance. When doing this check, it is important to have the low spot of
the platform in cutting position. I position the low spot at the lap. I
then use a red sharpie and make a big visible mark on the edge of the
platform so I am looking at the red mark as I am cutting . If you align
the mark at this spot for all adjustments, and cut with the mark there, a
very slight wobble in the platform will not be a problem.

Once you have the spindle true, and the platform aligned to it. then you
can focus on the handpiece. I am not going to go into details here as the
alignment is on my site and in my Lapidary Journal article. The important
thing to note though, is that you don't start making adjustments to the
handpiece until you have the rest of the machine in place. These are
sequence sensitive adjustments. This applies to the mast machines
also. If the mast/quill swing is not parallel with the lap, then angle and
index alignments don't mean a thing.

If your machine is fairly new, and still under warranty, I would send it
back to the manufacture to get the problems resolved. When describing the
problem, tell them what is wrong with the machine, not what is wrong with
the stones you are cutting. IE tell them that the platform is not swinging
parallel to the lap by 0.005". Don' tell them that you get a saw tooth
girdle. You are more likely to get the problem resolved by accurately
describing it in a manner that they can duplicate your observations. I
have found Raytech, as well as other manufactures to be responsive to
problems.

Other complaints about the Raytech revolve around the transfer jig. I have
yet to find a Raytech jig that was giving bad transfers, to be clean or
undamaged. The Raytech jig is a very accurate jig IF used correctly and
maintained. The V grove needs to be kept clean of wax, epoxy, and
dirt. It also needs to be dent free. The same goes for the edge of the
grove where the alignment pins go. The same need to be said about your
dops. They need to be clean and free of dents and dings. The alignment
pin needs to be straight. Dop technique is important. First, I never seat
the lower dop all the was to the bottom of the platform, but leave about a
mm of clearance. Make sure both the upper and lower dops have the pin
seated on the ledge correctly, both on the same side, the one where the
push lever is. When closing the two dops together, don't push the upper
dop down using anything other than the push lever. If you push on the dop,
you will rotate it and loose alignment. I always transfer using 5 minute
epoxy. I wet both the stone and the new dop. I carefully push the dops
together but I stop just short of contact between the stone and the new
dop, In other words, I bed the stone on the new dop in epoxy. This
prevents any spring action on the dops and the resulting miss
alignment. Make sure the epoxy is fully cured before removing the dops
from the jig. I place a 100W bulb about 4 inches away from the dops for
about 1 to 1.5 hrs to insure a good hardening of the epoxy. I then let the
jig and dops come back to room temperature before removing the dops. Make
sure you keep the new joint cool when removing the old dop. One last point
on dops is that they need to be EXACTLY the same diameter, and of a uniform
diameter. If they have a variance in diameter, IE measurements along the
length of the dop show 0.250", 0.249, and 0.248, the the dop is going to
set in the jig at an angle. If one dop is 0.250" and the other is 0.248",
then they are not going to be in radial alignment, but offset.

The index gear is the last issue I have with the Raytech, and one that I
haven't come up with a field fix for as yet. The problem is not that the
gears are cut wrong, but that the hub they ride on is sometimes slightly
undersized. Some of the gears have a bore that is slightly over sized.
When the two meet, a problem arises. You can get up to half tooth
mis-alignment of the gear on the quill hub with just 0.002" of
clearance. The "0" will not be a problem, but say on a 96 tooth gear, the
48 index will be off. The real problem with this is on
transfer. Everything looks good. The girdle facet a "0" index is still
flat on the lap, but as you start around the stone, things start to go
wrong. By the time you are at 48, you are way off. You started ;using the
cheater at about the 24 index and had to keep adding a little more as you
got to the 48 index. Now on the down side you are over corrected and have
to cheat the other way. It drives you nuts. The transfer jig is bad, you
just know it. The transfer jig is not the problem. To check out your
handpiece and gear, do this mount a dop with a big stone attached for a
handle. Now take the index gear nut off. Rotate the quill so the 48 index
is under the pawl. Now twist the stone right and left to see if there is
any play in the gear to hub. You are likely to see some. This play is how
much you will be out of alignment on the "back side" of the stone. As I
said, I don't have a field fix yet. A couple things I've looked at
follows. One would be to loosen the gear nut and fully rotate the slop out
at 48 and the tighten the nut. Cut the stone, and after the transfer,
loosen the nut and rotate the stone in the opposite direction from the
first rotation and lock down the nut. This should put you back in the same
alignment that you had for the first cut, although the '0" and "48" planes
would not be parallel. The other would to be using small shim stock to
"center" the gear correctly. I have not played with either of these yet as
I am lucky to have a gear that fits well. The real fix would be to custom
fit a set of gears to your handpiece. Some time after the first of the
year, I'll tackle this issue for a fix.

Hi Jill (and Ray),


I think I may just be able to help out a bit, with this quandary or
yours. As I see it (having used a Shaw facetor at length, some years back)
there are two or three potential culprits that could be responsible for your
recurring misalignment problems. Rather than jumping on one or another, I'll
describe them and pose a few questions, then let you do some investigating
at your end, in hopes of arriving at both an understanding and a solution,
or two...

A) An "aerated" dopping technique,

B) "Cold creep",

C) Mechanical misalignment or instability, and/or

D) Poor quality lap manufacture.

In the first case (An "aerated" dopping technique), could it be that
your dopping technique isn't quite what it could be? (And, G-d only knows,
mine was pretty awful, when I first began, years back!) When you dop a piece
of rough, what steps are you taking to ensure a seamless contact between
your point of control (dop face) and workpiece (rough)? In my technique,
which is almost always a shellac and/or dopwax one, I begin by grinding a
level "false table" with a fairly coarse lap, (such as a 180 or 260 to give
the dopping surface a bit more "tooth"), approximately where my final table
will eventually be located. When this is done, I swipe that surface clean
with Windex on a small piece of paper towel, then gently warm the rough
until dry, about 6" above a low alcohol lamp flame. When dry, I paint a thin
coat of Zinsser shellac onto the surface, then allow that to dry, as before.
Next, I warm a transfer-jig-held dop directly over the lamp in one
hand, and when hot, apply the dop wax in a "buttering" motion, first around
the dop's outer edge then in it's center. Next, I warm the stone, again,
about 4-6" above the lamp, while simultaneously holding the waxed dop 2-3"
above it; when the stone's shellac begins to bubble and the dop's wax flows,
I place the stone on the dop and, with a bit of paper towel to insulate my
fingers, press and rotate the stone into place (measuring and adjusting as
needed, in order to assure an ideal centering of the rough). This takes a
few seconds to a minute longer than many other techniques, but it alleviates
many of the problems I routinely hear others complain of, such as...

"Cold creep"! This is one of the (more polite) names given to what
happens if you either get a little bit of air in between your stone and wax
(as in an incomplete dop adhesion), or press too hard on the handpiece while
cutting or polishing. In short, the stone warms up just enough to slides or
shift its position, either from side to side or in an arc from top to
bottom, just enough to generate either that look on your face or those words
you tend to exclaim, or both! (Manipulative little pebble, isn't it?) The
only four ways around this are:

1) eliminate the chance of air bubbles and poor adhesion (i.e. shellac),
2) monitor the amount of pressure you're using, while faceting,
3) use both more and colder water drips as a cooling agent, to reduce
the chances of the wax warming and, thus, losing its stability, and
4) eliminate the chance of slippage, altogether, by using superglues
or epoxies, instead of waxes.

Have you considered any of these before, Jill?

Now, when you're cutting on the Raytech-Shaw F-1D (or its functionally
identical twin, the Imahashi), you come up against potential mechanical
problems not encountered in its "masted" counterparts. These have to do with
the both the nylon underpinnings of the handpiece (i.e. the two rear pins
which, along with the dopped stone, comprise the "tripod" structure of the
unit) and the threaded riser and rotating platen it sits upon. The first and
simplest cause of instability related to these has to do with those little
pins, and the beneath each of the two heel stops (rear "feet" of the
handpiece). Are they loose? Is it possible that they could be causing your
stone to lean, when you're cutting your tables? What about that platen? Have
you checked its evenness? (Often, on older machines, there're areas of wear
that can cause alignment problems.) Perhaps easiest of all, have you thought
to check the levelness of the platen with a carpenter's "bubble" level? (To
do this, simply place the level atop the platen in both "-" and "i"
directions, make note of the bubble's location, then repeat this with the
metal base plate base (from which it and the "master", or "lap" platen
arise.) Do all of those bubbles "agree"? If so, keep asking questions and
looking elsewhere; if not, a return trip to Raytech (for recalibration) may
be in order. Finally, a few words about faceting laps...
Those darned lap manufacturers! Sheesh!!! Sad, but true, Jill: in my
humble opinion, most faceting laps are made by folks with great
cabochon-cutting technology and hopes of capturing a second market. The vast
majority of flat laps are not truly flat: they either "crown" in the middle,
near the label, or "dish" in the middle and rise up at the outer edge.
Often, the electrobonded laps fall into the first category, and the
resinbonded ones, the latter. (You know those little "cheater" wheels on
your handpiece's heel points? This is why they exist: to overcome just such
problems.)
By the way, Jill and Ray (and other list readers): I don't know if this
applies to you, or not, but a great many of the faceters I've spoken with,
through the years, have puffed out their chests and boasted to me that
they've "never needed to resort to using a cheater". To my way of thinking,
that's like proudly announcing that you've never sunk to the level of those
who "actually" use the two left burners on their kitchen stoves! How much
ignominy can there be in using a feature on a piece of equipment that's
specifically designed to help us overcome alignment challenges and produce
better craftsmanship? (Just my $0.02 worth.) Well, that's both all the news
that fits, and all the time I can spare, to share it, at the moment! If this
batch of solutions doesn't do the trick for you, please don't hesitate to
pick up the phone and call (especially you, Ray and Jill, since we'll be
talking in a few days, anyway.) Until then,

All the best,
Doug

TODAY'S FUNNY ~

A farmer was milking his cow. He was just starting to get a good rhythm going
when a bug flew into the barn and started circling his head. Suddenly, the bug
flew into the cow's ear. The farmer didn't think much about it, until the bug
squirted out into his bucket. It went in one ear and out the udder.

I've lowered the price on my large lapidary unit to $700 which includes a
lot of extras and I'll even throw in the table it is sitting on. A
lapidary friend in Salem tells me this is a real good buy for somebody.
If I don't sell it by Xmas then I'll move it from Salem, OR to SC with
me.

I have a lap I'm hoping to swap with someone on the list, in exchange
for faceting rough. The lap in question is a Crystalite 260-mesh "Dot Disc"
WITHOUT CENTER HOLE (ideal for someone who cuts on either a Facetron,
Crystalite "Crystal Master" or any brand of 8" cabbing equipment with a
1/4"x20 tapped screw holder at arbor's end). I'd received this as payment
for some faceting lessons, last summer, and which has only been gently used
once (literally). This lap is great for speedy stock removal, especially of
large, included areas of rough. The reason I'm unloading it is that it fits
neither my Ultra Tec nor Lee faceters, nor my 6" cabbing setup. (Sure does
make a nice paperweight, though!)
At last check, laps like this listed around $150 and sold around $90;
I'm looking for one or more nice pieces of faceting rough, to total ~$75, or
thereabouts. (Beryls, fancy (orange, pink, green or yellow) Garnets, nodular
Tourmalines and clean Sapphires are my first picks but, if you can use this
lap, let me know what you have and we'll take it from there.)

Many thanks, in advance,
Doug

===================================

COMPETITIONS:

For All National and International Masters, Past-Masters and
World-Class Cutters:

This post is simply a reminder that in 2003 the USFG will host its
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 the
USFG's Newsletter, and since they have not been published since 2001,
some of you, who are most capable - skill-wise, may not
know about the competition, and some of you may have forgotten. The
"NAFC" is an OPEN Competition. Please note: The designs and rules
can be downloaded at <http://www.usfacetersguild.org/events.shtml>.
The closing date is June 20th, 2003; the amount of time between the
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." If further
information is needed, please contact me at <clmoon@pacbell.net>.

Subject: First USFG faceting list design competition.
Date: Thu, 21 Nov 2002 16:29:21 -0800
To: faceters@caprock-spur.com
From: Dan Clayton <dclayton@speakeasy.org>

First USFG faceting list design competition.

Design: Hexagon or Hexagon Cushion in Colorless or Colored Topaz

Judging: Highest number for total ISO values at 0, 10, 20,30, 40
and 50 degree tilt with five degree head shadow in GemFramx will
win. Example parameters are given below to achieve this configuration.
Online designs must be submitted by January 10, 2003. Design and
cut entries should have the design posted by that date but stone judging
will take place at the OPLC Hobnob in Tucson in February 2003.

Publication: All entries will be posted on the USFG faceting list site
and possibly on the USFG site as well. Designs may be included in
a USFG list CD. Designers maintain copyright to their designs but
must allow posting on the USFG faceting list site. Posting or publishing
elsewhere is not only permitted but encouraged.

Followup: Additional contests may be held for other shapes and
materials if there is sufficient interest and participation.

RI 1.61
head shadow 5 degrees
ignore glare no (default)
tilt movie yes (default)
starting tilt direction 0
ending tilt direction 5 (default)
maximum tilt angle 50
tilt increment 10
suppress VGA no (default)
concave no (default)
COS files no (default)
ISO files no ( you can enter yes if you wish
but it will fill your disk )
DISP files no (default)
exit files no (default)
starting file # increment each run if you wish to save images

Values for ISO will be summed and used as ISO total.
ISO Total will be deciding factor in judging but there will be 30
points deducted for a missed meetpoint. Fractional

Special recognition will be given to most original design as determined
by team of four judges selected by Jeff Ford or delegate/s.

Classes:

Individual,
all work must be done by one individual. In the
case of a fractional indices or an incomplete design a design
coach will explain how the problem can be fixed and the
entry will be moved to Coached class.

Team/Coached,
more than one individual from a club, guild or area may work together
as a team. If an individual wishes coaching they may do so but most
work must be done by the entrant with only suggestions by coach. This
means Fred Van Sant or some other designer can not do a design that you
enter as your own. I encourage friends, club/guild members to enter as a
team. Do not hesitate to enter if you need some coaching. We have design
mentors who are happy to help you.

Modified,
for a public domain design or a copyrighted design that the copyright holder
gives you permission to use. You enter design with modified angles, new tiers
or deleted tiers which gives "optimum" performance as determined by ISO
total. We will post at least two very basic designs you can enhance as you
please.

Design and Cut,
design will be posted and ISO Total noted but beauty of the finished stone
will be the judging criteria. Stones will be judged at the OPLC Hobnob in
Tucson. Individual, Team/Coached and Modified designs will be judged
separately.


I hope this format will encourage design and optimization oldtimers and
newcomers to get involved and hopefully develop their skills. All
entries will be posted on the site and may drive some traffic and interest.
I think ISO Total is as good as any single value to evaluate design
performance but we will look to improve criteria in the future.
