Subject: LapDigest News for Issue No. 101 - Mon 1/5/98

The index has been extended to include all issues up through
#100, and is stored in two files in the Archives:
IndexTo100Part1.txt and IndexTo100Part2.txt. The first file
is the one with the thread data. Use (GET filename) on the
Subject Line to access these two files.

Dave Daigle, the author of those two great papers on
Ammonites printed in Issue 100, has asked that the words:
"non-commercial republish permission granted" be added to the
two papers. Thus you are free to print them in your club
bulletins.

If anyone would like to help with the Digest, please let me
know. I have several small jobs which need to be done, none
of which require anything other than reasonable care and a
little time.

If your club or a school in your area is giving lapidary
classes, write and tell us about them; we are gathering a
list of where lapidary classes are taught.

There are several topics in the wings; these will be
published in the coming few weeks. If you practice any of
these in your shop, please let me know about it! They are:

.. how to do channel work (mineral inlay)
.. electroplating/deposition on lapidary items
.. surface decorations (etching. etc.)
.. how to make beads
.. drilling holes in lapidary items

I had hoped to present the following topics, but I do not
have anyone offering to write the articles. If YOU can write
on these topics, and will, please contact me:
.. lathe turning
.. mud saws

Have a great week! I hope you are back in the lapidary
workshop these days, when snow and ice make field trips
impossible! If so, be careful, but do have fun!

Subject: NEW: Reusing Cooling Liquid from a Cab Machine

I have two questions: first, is it possible to reuse the
coolant liquid after it has been run through (a CabMate, say)
and collected in a bucket?

(See below for second question)

Subject: NEW: Dangers of Cutting Malachite and Others

I have two questions: Second, are there any stones that are
dangerous to cut? I've heard that malachite releases
poisonous gases, but I would like to cut some (someday).
Anything else I should be careful with?

Bob

Subject: RE: Selecting a Cab Machine (was Equipment Query)

Hi, all.
I'm a newbie to lapidary, and it's very appropriate that I
find a discussion here about the Cabmate. After years of
talking about getting started "shaping rocks", my wife and I
bought a Cabmate for each other for Christmas. So far I've
polished a couple of geode halves and some small pieces of
rocks we've had lying around, but I cut my first cab last
night. It was a piece of moss agate that I had tumbled years
ago. I shaped it by eye (no template) then dopped it and
finished it off in a little while. My biggest mistake was
thinking that the process took longer than it did. I took
too much off the dome by trying to get it smooth on the 600
grit "Thin Disk". When I went over to the 325 diamond, it
smoothed nicely, though, and eventually polished up very
nicely.

Subject: NOTE: Collecting Ammonites


Congrats on the excellent article Dave. Thank You for
sharing your adventures with us, and may I wish all members
of this gathering a successful 1998, as you would define it.

May your work be hard, and beautiful!

Subject: WTB: Ultrasonic Drilling


I am looking for someone with an ultrasonic drill who is
interested in doing some custom drilling of gemstone beads.
Initially it would be rather small amounts (probably a couple
of hundred beads), but it may grow into a significant order.

If you have input to a club newsletter please pass this on
to the editor.

Thanks.
