I installed a downloaded DataVue zip file on XP and received an ODBC
error.  Is this a known issue; or more importantly, what is the "fix"?

A good question Bob. I am having issues with XP and Datavu also. I ended
up "cheating" by installing on XP then copying my instalation
directory from a working copy of Datavu on my windows 98 machine. I can now
view all the diagrams but cannot export them or open them in GemCadWin.

I have good news, and bad news.

First the good news...Get a sheet of glass larger than your lap. Lay the
lap in the center of the glass, working face against the glass, which
you may want to dampen with a rag or spray first. Pressing down _firmly_
rock the lap face across the glass in at least three different
directions, but be careful to return to the original position, and to
not rotate the lap relative to the glass. Don't be afraid to move 1/4
inch each direction, but try to keep it under 1/2 inch at all costs (and
shorter may be better). Turn the glass and lap over together, and you
should be able to identify from the larger/deeper scratches exactly
where the contamination is. Dab the spots with red fingernail polish and
avoid the red lines on your spinning lap if there are only a few.
Consider yourself lucky.

The bad news...is that the lap is usualy hopelessly contaminated instead
of localized. Recharge it with coarse, or take it to a machine shop for
resurfacing (at a premimium due to the existing diamond charge). If you
are not lucky, Lava Soap (that is also great for cleaning slabs!),
backwards work with the edge of a piece of glass, and maybe a tack
hammer and trimmed tip (to flatten a small hard point) flooring nails to
crush/fracture the larger contaminated points will occasionally salvage
a lap,

The lesson is that being a clean freak, expecially when changing stages
with diamond (you can often get away with it using carbo because it
breaks down on hard use), is worth the bother. The experience of
telescope makers says that most contamination occurs from under the
fingernails. Clean the area, and then clean yourself -- after packing up
the coarser grit, and before breaking out the finer grit. Then clean the
area, and yourself again to make sure you didn't leave anything 'large'
behind the first time.

There is nothing worse than diamond contamination if you are trying to
make a polished surface.

Hi Every One,

I just got back from a rock collecting trip to NC. I had a great time
getting rocks and gems like rubies, Sapphires, Garnets, Unakite, Apatite
etc. I like going to the Little Pine Garnet mine  for garnets, we found a
five gal. pail full in about five hours of digging. the cost is $5.00 a day
to dig there. The fee at the Old Pressley Sapphire Mine is now $25.00 a day.
It's to bad the USFS closed the road going up to the Ray Mine. Now you have
to walk up to the mine. You can find Aquamarine, Golden Beryl, Tourmaline,
etc. there. The Ray Mine is near Burnsville NC. We need your help to try and
get the road back open buy having you all call the US Representative -
Congressman Charles Taylor at 1-202-225-6401 and tell him you would like to
see the road reopened up. I was told that he does listen to the people. And
you can call the Forest Service at: 1-828-682-6146 and complain to them
about the  closing of the road and that you want it opened up. They are
discriminating against the disabled by keep them from getting to the Mine.

As Denney says there are a lot of mines to go to and find great gems. In
Oct. we are going to have another rock hound outing, if you are interested
in coming go to Mcrocks board at:
http://www.dream-tool.com/tools/messages.mv?index+mcrocksnet and watch for
the time and place. Oh the date for this is the weekend of Oct. 26th. KOR

Warm regards

Date: Tue, 1 Jul 2003 13:50:41 -0400

From: <sinico@nbnet.nb.ca>

Hello everyone,

A friend and I have been discussing doing the Big Sur Jade Festival in October,
and in that respect I would like to throw myself upon list members' collective
technical wisdom.

The festival is outdoors. No electricity. Yet people love to see stuff being made
- so I would dearly like to be able to do facet cutting on the spot. This in turn
means getting-borrowing-renting a generator.

But how big a one?

The faceting machine runs on a 1/4 horsepower motor. 1 HP = 746 watts, so a
quarter horse should draw 180 watts give or take. Two lightbulbs worth in 
effect. Yet that just does not seem plausible to me. Surely the motor must draw
more than that?

Ideal would be a generator that could run a standard 1/4 HP washing machine motor
plus about 10 100-watt lightbulbs.

Does anyone know enough about electrics to advise what rating of generator we
should look for to do that? We've looked on a rental website and found a 5,000
watt generator that is reasonably affordable. Yet my primitive calculations above
suggest that 5,000 watts would be way too much??

Any words of wisdom would be greatly appreciated...

Ohm!

Hi Hans, A 1200  watt should do the trick but you might also consider a "no
noise" solution by using a 1200 watt inverter and a couple of car batteries.

Hi, my name is Sal. I have been on you list for quite awhile. I really
enjoy reading all the hints and tips.
I live in the New York City Area. Is there anyone you know that would be
willing to give instruction in faceting.
I belong to SIGS the Staten Island Geo Club, They do some cabbing but donot
have any faceters. I have been faceting for a while but have reached my
self-teaching limit.

Thankyou
Sal

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 visible difference as you turn the dop this will be your problem.
I had to replace the old spindle on my machine several years ago and it is
expensive.
Tom Nuchols, Mount Pleasant, Texas
**********************************
all older UltraTec Stanley owners:

There were some tapered chucks that were produced in past days that had
considerable offset error in the chuck and or spindle pair.  Assuming that
the spindle is ok and not worn or damaged, the chuck needs to be replaced.
But it is also quite possible that the spindle is also the issue.

I recently talked to a fellow club member about this very problem.  He had a
0.004 misalignment in the spindle/chuck and couldn't make the girdle facets
(or many others also) match on any cut.  This unit was bought by him from
another person as a very old used unit.  He found that UltraTec couldn't
resolve this problem because the older Stanley machines were not
manufactured to the current UltraTec tolerances.  These machines do need to
be upgraded to current spindles without the dop chucks to be capable of
operating correctly.  There isn't any intermediate solution that can be
supported by UltraTec that will work.  I'd recommend that you contact
UltraTec (714.542.0608) (Info@ultratec-facet.com) to price out a new
spindle.  All of these machines are capable of being upgraded.  I have done
this to my older Stanley machine as Tom Nuchols did also.  It was really
worth it.  I'm very happy with the performance now.

TODAY'S FUNNY ~

In a terrible accident at a railroad crossing, a train smashed into a car
and pushed it nearly four hundred yards down the track. Though no one was
killed, the driver took the train company to court.

At the trial, the engineer insisted that he had given the driver ample
warning by waving his lantern back and forth for nearly a minute.  He even
stood and convincingly demonstrated how he'd done it.  The court believed
his story, and the suit was dismissed.

"Congratulations," the lawyer said to the engineer when it was over.   "You
did superbly under cross-examination."

"Thanks," he said, "but he sure had me worried."

"How's that?" the lawyer asked.

"I was afraid he was going to ask if the lantern was lit!"
