There is sufficient lead length so they can be clipped off right at the PC
You can use the 5K trimpot (One of the small Bournes blue ones) on the PC
Board as the calibration pot.
I just got mine and have a system running now.
I am also building a calibration fixture so that I can qjualify various
models of sensing pots. There is a possibility that linearity errors in
previous versions, prior to the Datel DPM were partly caused by the cheap
When I am done this week I will put an additional page up so that the

Sometimes you can sacrifice a piece of quartz or maybe glass and run the
lap DRY while pressing moderately in several 'tracks' while looking for
a distinct white 'swarf' track. If this works on these fine laps it will
do 2 things; tell you where to concentrate remediation efforts and give
you a test for success.
I have actually cleaned a lap once using a piece of wood(it was an old
600). I seem to recall that I ran the lap in reverse and kinda pointed
the wood up streem and downstreama a few times while pressing kinda
hard. maybe some plastics or other substances would work well too.
If all else fails, maybe a Sharpie or other marker would at least give
you an area to avoid and the rest of the lap could be used somewhat -
depends on just where that contamination is.
let us know whatever you do - we could all use the feedback!

The type of contaminated laps was not mentioned in issue 157, Friday, 6/27/03, so
what I have to say may not be entirely applicable. However, I'll jump right in
and suggest scrubbing the laps with a bar LAVA soap. This has often solved not
only contamination problems, but has removed embedded swarf or otherwise renewed
surfaces on resin bonded laps, giving me much better cutting. I have used this
technique more often on cutting and prepolish laps 1200 grit and below. I have
also had success on phenolic laps impregnated with 3000, 8000 and 14000 grit. If
the LAVA soap doesn't solve the problem, the use of medium to fine grit sandpaper
in an orbital sander, applied evenly and carefully so as not to adversely affect
the flatness of the lap, should solve the problem. If you're using a metal lap,
e.g., tin or BATT, it's probably best to have the surface turned down a few
thousandths on a precision metal lathe.

This will be probably the 14th post that advises to use lava soap on the
contaminated laps. Get a bar of Lava soap and scrub your laps with it. On
a firm surface place the laps face up and put a bit of water on the soap and
lap. Rub the end of the bar in a circular motion around the lap two or
three times. Wash the soap and residue off the lap then see if it is still
contaminated. If so repeat the process. Usually the process does not have
to be repeated more than twice if done properly. Store your laps in plastic
bags to reduce the chance of contamination.
Hope this helps.

Most people on this list are very generous with their designs and more
than willing to share. There was a program of designs from many well
known faceters available free of cost called Data Vue. It was meant to
encourage faceters to try many designs and there were no strings
attached. There are of course designs presented in such a manner as to
cost money. For the longest time these coexisted with no problem. More
recently there appeared an attitude that free designs "competed" with
those for sale and an effort was made to stop the availability of Data
Vue. Sadly DataVue is now an empty shell. There are some online that
already have the full program and and may quietly share. I do not as I
use a Mac and these programs other than Fred Van Sant's original Apple
program do not work with my system.
Also check Bob's Rock Shop for many designs free for the taking. There
are other resources and I feel certain you will get those from others
online. Facet designs are a labor of love and many achieve happiness by
freely sharing their designs. They feel honored to be asked and even
more so to be thanked by an appreciative recipient.

Have you seen Jerry Capps' Kansas Triangle in the Feb 2003
Lapidary Journal? I think it may have enough facets if not you
might want to add a few more assuming you are good with
Gemcad. Jerry Newman has a nice trilliant which was the
masters design for the competition in Ventura recently. It doesn't
look real easy to cut but I think if you just work your way thru
and are careful at each step it will cut just fine. Art Kavan didn't
seem to have much problem with his stone but he is world class.
Jerry had several of these cut in various materials at his booth
and they looked great. Jerry's email is firstname.lastname@example.org.
I will send you a trangular design I did but haven't cut yet if you
want to try that. I haven't seen many triangular designs with a
lot of facets. It seems to me that triangular cuts are often very
brilliant but maybe that is just the ones I have seen and cut. I
do not put any faith in all the discussions of odd or even
symmetry being brighter or more lively until I see proof from
a well designed experiment.

If you have one of the old Stanley Ultra Tec"s that has seen heavy use
the tapered chucks may have worn off center. Place the machine at 90.0
Degrees and place a light behind the lap about lap level. Place a
long straight dop in the chuck and lower the
dop so that it almost touches the lap and look at the area between
the dop and the lap. Turn the dop to several different
indexes and observe the area between the lap and the dop. If you see
visable difference as you turn the dop this will be your problem. I had
to replace theold spindle on my machine several years ago and it is

Hello Thurmond and All,
I want to give a suggestion on contaminated laps that was passed on to
me. It regarded laps contaminated mainly with wax, but I thought I
would pass it on anyway. It may/may not help for the gentlman with the
3000/8000 contaminant problem.
Here goes: I was told to spin my lap, with a bit of water, not much,
and use a bar of lava soap on it until it is caked up. Then take it and
scrub it, with a scrub brush, under hot water. Try this one or two
times to clean up the lap.
I can't guarantee it will work for bort contamination, but it is worth a
Stay Cool and Drink alot of Water in the Heat,

TODAY'S FUNNY ~
The story is told of five doctors went duck shooting one day.
Included in the group were a GP, a pediatrician, a psychiatrist, a
surgeon and a pathologist. After a time, a bird came flying overhead.
The first to react was the GP who raised his shotgun, but then
hesitated. "I'm not quite sure it's a duck," he said. "I think that I
will have to get a second opinion." And of course by that time, the
bird was long gone.
Another bird appeared in the sky thereafter. This time the
pediatrician drew a bead on it. He too, however, was unsure if it was
really a duck in his sights and besides, it might have babies. "I'll
have to do some more investigations," he muttered, as the creature made
good its escape.
Next to spy a bird flying was the sharp-eyed psychiatrist. Shotgun
shouldered, he was more certain of his intended prey's identity. "Now,
I know it's a duck, but does it know it's a duck?" The fortunate bird
disappeared while the fellow wrestled with this dilemma.
Finally, a fourth fowl sped past and this time the surgeon's weapon
pointed skywards. BOOM!! The surgeon lowered his smoking gun and
turned nonchalantly to the pathologist beside him: "Go see if that was
a duck, will you?"

The Real Cost of Having Kids
I have seen repeatedly the breakdown of the cost of raising a child, but
this is the first time I have seen the rewards listed this way. It's
nice, really nice!
The government recently calculated the cost of raising a child from
birth to 18 and came up with $160,140.00 for a middle income family.
Talk about sticker shock! That doesn't even touch college tuition.
But $160,140 isn't so bad if you break it down. It translates into
$8,896 a year, $741.38 a month, or $171.08 a week. That's a mere $24.24
a day! Just over a dollar an hour.
Still, you might think the best financial advice says don't have
children if you want to be "rich." It is just the opposite.
What do your get for your $160,140?
Naming rights,--- First, middle, and last!
Glimpses of God everyday.
Giggles under the covers every night.
More love than your heart can hold.
Butterfly kisses and Velcro hugs.
Endless wonder over rocks, ants, clouds, and warm cookies.
A hand to hold, usually covered with jam.
A partner for blowing bubbles, flying kites, building sand castles, and
skipping down the sidewalk in the pouring rain.
Someone to laugh yourself silly with no matter what the boss said or how
your stocks performed that day.
For $160,140, you never have to grow up.
You get to fingerprint, carve pumpkins, play hide-and-seek, catch
lightning bugs, and never stop believing in Santa Claus.
You have an excuse to keep reading the Adventures of Piglet and Pooh,
watching Saturday morning cartoons, going to DisneyLand, and wishing on
You get to frame rainbows, hearts, and flowers under refrigerator
magnets and collect spray painted noodle wreaths for Christmas, hand
prints set in clay for Mother's Day, and cards with backward letters for
For $160,140, there is no greater bang for your buck.
You get to be a hero just for retrieving a Frisbee off the garage roof,
taking the training wheels off the bike, removing a splinter, filling a
wading pool, coaxing a wad of gum out of bangs, and coaching a baseball
team that never wins but always gets treated to ice cream regardless.
You get a front row seat to history to witness the first step, first
word, first bra, first date, and first time behind the wheel You get to
You get another branch added to your family tree, and if you're lucky, a
long list of limbs in your obituary called grandchildren.
You get an education in psychology, nursing, criminal justice,
communications, and human sexuality that no college can match.
In the eyes of a child, you rank right up there with God.
You have all the power to heal a booboo, scare away the monsters under
the bed, patch a broken heart, police a slumber party, ground them
forever, and love them without limits, so one day they will, like you,
love without counting the cost.
ENJOY YOUR KIDS AND GRAND KIDS!!!!!!!
