I guess I have humble tastes in autos.  As long as they are from Coventry.

True, I am no good at golf, and my attention span is too short for fishing.

If you take a look at ANY faceting machine, it is obvious there is a lot of
work in them.  Little parts, fussy tolerances, critical assembly, etc. and
from what I have seen so far I genuinely doubt anyone is making obscene
profits by building them.  Just costing out parts and materials alone, and
allowing a basic shop rate, than adding G&A and overhead at usual rates, I
think anyone with a calculator has to see that.  The only ones making money
are UPS and Fedex, who sent me a cheery Holiday note announcing yet another
price increase.

I received a specimen of Bytownite today in the mail. It came with a
chunk of rough and a 1 cm cut stone. It was labeled "Anorthite, var.
Bytownite". Checking www.mindat.org shows Bytownite is not an accepted
mineral name, it is triclinic, and it has a hardness of 7. Optical data
was also available, but nothing on clevage.

I just started using WD40 to clean BATT, Corian and copper laps a couple
months ago after a suggestion from Paul Head or Gearloose. It makes such
an amazing difference on BATT with 3K diamond for prepolish that it is hard
to believe. I just use a couple pumps of WD40 when I clean up then remove
with a bit of paper towel triple folded. It cleans much more swarf than I got
off previously and the prepolish looks almost like it was 100K. Well not
quite but you will think you were using the wrong lap. The technique works
fine with 100K or oxides. Also works fine with 8K diamond on BATT, Corian
or copper which I sometimes use. For a small stone I may not need lube
at all with BATT if I did clean up with WD40. I use a few pumps from my
olive oil spray if I need lube. One part olive oil and five parts alcohol in
a clean spray bottle makes a good lube. Straight olive oil is too messy,
you just don't need that much lube and it gets in the way. Polish or
prepolish is much faster without all the swarf to slow down the process.
BATT laps are so slick you may not need lube. I wipe off part of the lap
when I start to see swarf build up. Most people are probably using too
much lube and diamond. Hope this helps. You can probably find little
2 ounce spray bottles in the local Walmart for 50 cents to put all your
spray concoctions in. A half carat to two carats of diamond bort in
one of these bottles filled with alcohol makes a good diamond spray.
I haven't tried making my own diamond compounds yet but I think
the gunk in many compounds gets in the way of the diamond and
makes polishing difficult.

Have a good Christmas and a great new year

Bob,

Bytownite does have perfect cleavage in one direction and good in another,
but I have cut a quantity of Bytownite in a variety of designs and have not
had any problems with either cleavage plain. When cutting Bytownite I orient
the rough with disregard for the cleavage.

The Bytownite that I have (from Mexico) tests at a hardness of 6 - 6.5. I
use the angles published for Feldspar, and have found that it polishes well
with cerium oxide.

Good luck
Randy

Subject: BC collecting and bytownite cutting

To: lapidary@caprock-spur.com
From: denney.wilson@att.net

     First, as to collecting in BC, I have found a way to do it that is both
fun and safe and, usually, productive, at least for cab grade material.  I
have found that if you go to any of the public but not popular beaches north
of Vancouver, you can walk the water edge at low tide and find quite a
collection of material that is cuttable.  I have found small pieces of jade,
rhodonite, various quartzes, and many attractive amalgams.  It is not the
best grade material, at times, but sometimes it is very good.  Again, usually
this is cab material, but it is free and fun to look for!
     Next, to cut bytownite with few problems, find a cleavage plane and then
simply grind a dopping table at about 7 to 15 degrees from that or at 75-83
degrees from that, depending upon the shape of the rough.  There then seems
to be no problem with either breakage or polishing but you can have some
problems with color if you choose the wrong axis.  It can turn rather dull
brown and nobody seems to like that!

Can anyone help me get data vue running in windows XP. I installed gemcad but
can't get the program to import any designs. I have been faceting for only
three years and love this hobby.

Thanks,
Larry

This isn't about lapidary, but I thought it important enough to send in:

I recieved this message from a friend:

Someone I know at work received a telephone call last evening from an individual
identifying himself as an AT&T Service technician who was conducting a test on
9 0), the pound sign (#), and then hang up.
Luckily, I was suspicious and refused.
Upon contacting the telephone company, I was informed that by
pushing 90#,
you give the requesting individual full access to your telephone line,
which enables them to place long distance calls billed to your
home phone number.
I was further informed that this scam has been originating from
many local jails/prisons. I have also verified this information
with UCB Telecom,PacificBell, MCI,BellAtlanticand GTE. Please beware.
DO NOT press 90# for ANYONE.
The GTE Security Department requested that I share this information with
EVERYONE I KNOW. PLEASE pass this on to everyone YOU know.
If you have mailing lists and/or newsletters from organizations you are
connected with, I encourage you to pass on this information to them.
After checking with Verizon they said it was true, so do not dial
(9),zero(0), the pound sign # and hang up for anyone.

DOG PEEVES ABOUT HUMANS

Blaming your farts on me... not funny... not very funny at all!

Yelling at me for barking... I'M A  DOG YOU IDIOT!
Taking me for a walk, then not letting me check stuff out.  Exactly
whose walk is this anyway?

Any trick that involves balancing food on my nose... stop it!

Any haircut that involves bows or ribbons. Now you know why we chew
your stuff up when you're not home.

The sleight of hand, fake fetch throw. You fooled a dog! What a proud
 moment for the top of the food chain.

Taking me to the vet for "the big snip", then acting surprised when I
 freak out every time we go back

Getting upset when I sniff the crotches of your guests. Sorry, but I
haven't quite mastered that handshake thing yet.

Dog sweaters. Have you noticed the fur?
