Hi All, 

Hi All, Did you miss the digest? So did I but the membership
is not posting so the digest has not been produced. I thought
the 10 post rule would help but it has hurt instead so the digest
will now be produced once a week on Friday unless the membership
can greatly increase the posting volume. Too bad because I know
that like myself many of you looked forward to a daily digest.
There are over 1030 members so 10 post a day should not be too much
to expect.  The USFG list has less members but usually has 5 to 20 post
per day. Suggestions?

Thurmond

making
up case displays of stones, etc. >>

Heck, I'm *ONLY* 44, I've been cutting since I was 17, and I am currently
giving cutting lessons to my 11-year-old son. I let him use my BATT laps but NOT
my Gearloose XS3!
I think one of the factors giving rise to Glenn's lament is time - some of my
favorite faceting friends have been people that are retired, and have the
time to cut purely for fun. I don't (yet) have that luxury, though one of my
career goals is to be retired.
Also, in my humble opinion, those faceters who claim NOT to have a case of
show stones are fibbing! I cut for customers, but I have my favorites that will
never be sold - and I suspect so does anyone else who has ever faceted.
So never fear - young people are still coming into the hobby!    -Charlie

Hello the List--
My sweetie has a bias against synthetic stones. But, when I showed her  a
round brilliant done with strontium titanate, she said, "I want one." She
is getting three for Christmas. If anyone cares to see them, they are at
http://www.the-gemmery.com/Stones/Stone%20Information,%20Pictures/strontiumtitanate.ht
m
As usual, the colors don't all come out in the photos.
Strontium titanate is a bit soft for jewelry, with a hardness of around 5
or 6, but I think it would be okay
for a pendant or earrings. The stone has an amazing dispersion, and its
colors just jump out at you.
I just bought a BATT lap, and these are the first stones polished on it.
The table on the larger stone (7mm) took maybe a couple of minutes, and I
understand the lap will polish even faster as it ages.

For those who knew, yesterday was the surgery day and it is over and
done with. I was apprehensive, but all went smoothly. They forgot to
pick me up today for a post op visit, so it will be tomorrow.

I do need to rest the eye some, so may have less computer time for awhile.

I'd like to thank everybody who posted information on Tangent Ratio. I
have GemCad Dos but didn't know about the TR feature and completely
forgot the waytrace. What I have found out is basically if the design is
a lower RI you should not worry. But if the design was specifically done
for higher RI you should TR the design to cut in a lower RI stone. CZ
design cut in Quarts will not reflect light. This may be over simplified
but to use hobbyists it should work. The operative word here is
"should". LOL! Again thanks to everyone.

Subject: NEW: RUBY LASER ROD
Date: Wed, 10 Dec 2003 12:27:17 -0600

From: Doug Smith <gembin@spiff.net>

Hello All,

Although I have not cut a stone in almost a year, I purchased a ruby
laser rod last night that will probably get me started again. It is 6"
long X 3/8" diameter. It is polished on each end, but not silvered. When
you look through the end, it's as if you were looking through a clear
soda straw only giving everything you view a pink tint as if you were
wearing pink sun glasses. I mentioned this laser rod on another
(defunct) digest some time ago. The fellow that owned the rod wanted me
to cut a stone for him and one for myself. Because I still consider
myself as a newbie, I declined his offer as I was afraid if it didn't
turn out to his satisfaction, I didn't want to loose a friend because of
it and suggested he find someone else to cut it. To sum it up, he sold
the rod to me last night.

My reason for giving the background story on this is when I posted it on
another digest (which was a happy digest back then), I asked for help
with refractive index, cutting angles and designs for cutting and
received loads of help with information. Sadly, I have lost my notes on
it. I guess the best cuts would be the SRB and possibly the emerald cut.
I would appreciate any suggestions you might have and any designs on the
internet that I might download. Seems to me that some suggested the rod
might be YAG.

Best Regards,

Hi Doug, All the YAG rods I have seen were clear (colorless). It sounds like you have
a true "Ruby Rod" (corrundum).

I am just an amateur faceter (35 years) but I really like to read all
the newsletters and appreciate the work done on them.  I have Gemcadwin,
and love it, but have not been able to figure out how to extract a
gemcad file that is in a newsletter and get it into a gemcad file.  I
always end up with the message 'corrupted file'.  Can anyone help?  Chet

I haven't had a Digest since Issue 254 of Monday December 8. Is this due
to a lack of posts or is there some other reason? If lack of posts, then
I suggest that you send a weekly email which contains all (or none)
posts received that week. That way there would be a confirmation to
people that they hadn't just accidently dropped off the mailing list.
Also it might just jog some action in the way of questions. :>)

Hi Arch, No post, No digest. I will publish on Friday's ONLY from now
until posting volume increases greatly.

Hi Thurmond,   Whenever I need to TR a diagram I use the handy paper
slide rule I made from a Robert Strickland article published in Angles
in 1996.  Every faceter should have this.  It's very slick. I'll try to
send as an attachment, but I'm not sure  you can receive it. If it
doesn't get to you perhaps Robert can somehow get it to you properly so
faceters can access it.    Regards,   Jerry Newman

Hi Thurmond,   Hope you can match up with my post.  I want to make sure
Robert Strickland gets the credit for preparing the article I read back in
1996 on tangent ratioing.. I have used the slide rule on quite a number of
occasions. It works well.      Jerry

TODAY'S FUNNY ~

Thoughts For Those Who Take Life Too Seriously:

Save the whales. Collect the whole set.

A day without sunshine is like, night.

On the other hand, you have different fingers.

I just got lost in thought.  It was unfamiliar territory.

42.7 percent of all statistics are made up on the spot.

99 percent of lawyers give the rest a bad name.

I feel like I'm diagonally parked in a parallel universe.

Honk if you love peace and quiet.

Remember, half the people you know are below average.

He who laughs last, thinks slowest.

Depression is merely anger without enthusiasm.

The early bird may get the worm, but the second mouse gets the cheese.

I drive way too fast to worry about cholesterol.

Support bacteria. They're the only culture some people have.

Monday is an awful way to spend 1/7 of your life.

A clear conscience is usually the sign of a bad memory.

Change is inevitable, except from vending machines.

Get a new car for your spouse.  It'll be a great trade!

Plan to be spontaneous tomorrow.

Always try to be modest, and be proud of it!

If you think nobody cares, try missing a couple of payments.

How many of you believe in telekinesis?  Raise my hand...

OK, so what's the speed of dark?

How do you tell when you're out of invisible ink?

If everything seems to be going well, you have obviously overlooked something.

When everything is coming your way, you're in the wrong lane.

Hard work pays off in the future. Laziness pays off now.

Everyone has a photographic memory; Some just don't have film.

If Barbie is so popular, why do you have to buy her friends?

Eagles may soar, but weasels don't get sucked into jet engines.

What happens if you get scared half to death twice?

I used to have an open mind but my brains kept falling out.

I couldn't repair your brakes, so I made your horn louder.

Why do psychics have to ask you for your name?



AND THE ONE I RELATE TO THE MOST THESE DAYS - - -

Inside every older person is a younger person wondering "What happened?!"
