> To the individual with the stuck/locked dop.  You may want to try a product called
Silicroil (sp?) or sim. product.  Mix of silicone and penetrating oil.  Apply to dop
housing (space between dop and handpiece) and allow to sit for a day.  Twist dop out
with vice-grips so you don't damage handpiece.  Product is able to move between two
bits of metal while under 1,000,000 psi.  Never had it not work on metal parts that
are locked together.  Good luck.

Hello,

Well Gerry beat me with a full cut SRB at .75mm, mine was a huge
1.2mm but I did it for a customer and don't have it anymore. I'm
currently in the middle of replacing all the stones in an
antique ring that surrounds the diamond with thin baguette
sapphires. The biggest so far was a trapezoid 2.2 x 1.2 the rest
of them are below 1mm in width. I'll take a picture when I'm
finished.....10 more to go.

------------------ clipping from the net -----------------
Many famous diamonds were cut and polished in Amsterdam. For
example, the "Cullinan", the largest diamond ever found. 
Furthermore, the world's smallest diamond, just 0.00012 carat,
but with 57 facets, was also cut in Amsterdam.
------------------ end of clipping -----------------

Hey Clyde,

You wrote;  Needless to say, my handpiece is ruined
and I am dead in the water. The only culprit I can find is the new dops-

Do you mean that the handpiece is ruined because the dop is still there,
or was it damaged trying to remove the dop??
If it's the former you can drill the dop to remove it. You don't have to
drill the full size and take a chance on damaging the sleeve. If it's a
1/4" dop, then a 3/16" drill will relieve the pressure, allowing
removal. If you don't feel comfortable doing this yourself, find a
machinist to do it for you. And while you're at it have him mic the rest
of the new dops and document the results.  If the tolerance is very
close to the size of your sleeve, what might have happened if your
handpiece/sleeve was pretty warm, ( and thus expanded), and the dop was
cool(and slightly smaller), the dop could have gone in snugly, but then
when the two came to the same temperature the dop was stuck.  This is a
common practice in machine shop work called shrink fitting.  If done
properly,(or by mistake in your case), it will seal openings that will
withstand thousands of lbs. of pressure, hold bearings in place, or hold
the 1" mast in its base on my homebuilt faceter against strong forces
without any other means to secure them.
hope this helps,
pauly, ( a retired machinist of 38 years)

Subject: Tapes of Faceters Symposium 2003
Date: Wed, 27 Aug 2003 08:13:36 -0700 (PDT)

Hi All:
 
The tapes taken at the Faceters Symposium 2003 at Ventura last June are being worked
on by a person set up to edit tapes.
 
We made the original tapes with about four different formats, my VHS version being
one of them.  It has turned into being a challenge to get good audio and good
pictures from the variety of masters to work with.....but I am not giving up, so
please be patient and keep your interest in obtaining copies of the speaker
presentations.
 
As it looks like now, it will still be some weeks before we have the completed Master
set, which will be our source to make duplicates.
 
It is quite a challenge to get the audio good, when speakers move around away from
the podium, etc.  And then, to pick up the questions or remarks from the audience is
difficult.  We Symposium staff members are amateurs at this.....certainly cannot
claim to be experts like World Class photographers.....
 
I have kept the names of those who showed interest in the tapes by giving me their
name and address at the Symposium.  I also kept the names of those who emailed me
direct to get their name on the list.  Any of you faceters that are interested in
purchasing the presentations can still let me know.  I promise you that I am not
forgetting about this tape project.  I will see it through to completion.  And the
Faceters Guild of Southern California wants these to be of the best quality that we
can get together....it will just take time.  But please do not lose your interest.  
 
I believe the set of presentations could be good items to use, one speaker at a time,
at one of your local Guild's meetings per month.  I envision two presentations on
each two hour tape, with a total of five tapes, and a price that is reasonable for
the set of five tapes.  I do not want to get into supplying one speaker on one tape,
etc.  That would just draw the cost up for the total of five tapes.  We may end up
also having the presentations on a DVD.
 
Hang in there.

TODAY'S FUNNY ~

Is Windows a virus?
With the recent problems being encountered by Windows users
all across the country, people are begin to ask themselves if
windows is a virus. In response to the high demand for an answer
to that question a study was done and concluded the following.

1. Viruses replicate quickly.
Windows does this.

2. Viruses use up valuable system resources, slowing down the
system as they do so. Windows does this.

3. Viruses will, from time to time, trash your hard disk.
Windows does this.

4. Viruses are usually carried, unkown to the user, along
with valuable programs and systems. Windows does that too.

5. Viruses will occasionally make the user suspect their system is
too slow (see 2) and the user will buy new hardware.
Same with Windows, yet again.

Maybe Windows really is a virus.

Nope! There is a difference!

Viruses are well supported by their authors, are frequently updated,
and tend to become more sophisticated as they mature. So there!
Windows is not a virus.
