Has anyone here tried glass etching with the Dremel high speed rotary
tool (or the new Black and Decker Wizard, as I think it's pretty much
the same thing)? Which bit would you recomend for this? The Dremel
manual suggests a tungston carbide tip but it seems to me the diamond
coated tip would be better.

I also have an Inland Engraving pen that I use to sign my work, but that
just seems to scratch the glass, rather than really carving it.

I am curious as to your source for the diamond cutting disks, as I use a
dremel for many things, but not for glass.
Thanks, Anne

Thats somthing I would be interesed in. Would you object to sharing
you source?
I learned glass engraving with a Dremel. I would heartily recommend a
flex shaft, and only use diamond tools. The most useful basic bit seems
to be the 1/8 inch diamond ball. I do a lot with a 1/16 inch ball, a 1/4
inch cylinder, a 1 inch round edged wheel, and a 1 inch V wheel. (sorry
folks, I usually post english and metric, but I'm feeling rather tired
today).
Here's my beginning engraving resource list.
Graham, Boyd "Engraving Glass, A Beginner's Guide". 1982. Dover
Publications, Inc. New York.
At $8 US, this book has the highest bang for the buck of anything I've
ever purchased. It's all geared towards flex shaft engraving, Dremel or
Fordham style. Includes the basic bits and the cuts they make, how to
build a drip table for water cooling, first lessons, and quite a bit on
polishing and displaying. It's still in print, and in stock at Amazon. I
don't know any other book which comes close.

Very smooth running burs, and their (rather pricey) mini-turbine wheel
is the most glass grinding destructive power that you can fit on a
dremel or a fordom.

I have a love/hate relationship with Lapcraft. Their 8 inch pull back
disks are the mainstay of my grinding operation. But I've had their
small stuff (1 inch bits) peel out alsmot immediatly upon use. Theit
return policy needs work. I love their two inch slitting saws

Carries Eurotool, a very smooth running burr. Only a mile from my house,
carries a good variety, and is right next to Kathy's Cheesecakes. What
more do you want in a lapidary and jeweler's supply.

I always use water. I use one of two techniques. One is a "drip table"
which is just a big slab of flam sponge in a pan and an overhead water
source which goes "drip drip drip" on your piece. The other is the
slassic little chunk of wet sponge held against the bit. It doesn't take
much practice till you find a position which lets you hold an engraver
and a wet sponge in one hand, and the glass in the other.
Control of pressure and water controls finish. Lots of water, moderate
pressure, and high speed keeps flushes away the glass dust and keeps
diamond in contact with the glass for a fast, but rough, cut. Less
water, less pressure, and less speed lets glass "paste" coat the bit and
results in a natural polishing action.
Good safety glasses are a must. Glass dust is abrasive and must be
rinsed off your safety glasses, not wiped off, or you will soon ruin the
lenses.
Even wet, glass dust is toxic. Dry, it's really nasty. Not only is it
inert, sharp edged glop that the human body cannot easily purge from the
lungs, but fresh glass dust is full of broken, high energy bonds,
looking for any opportunity to recombine. It hits the lung tissue like
acid. Invest in a good respirator.
Get a flex shaft, and hang the dremmel from a ceiling hool or something.
You have much less to worry about in regards to water in the power
tools, and you have a small, cool flex shaft tool to hold, instead of a
big, hot, vibrating motor.
Here's my best "magic" hint. (As far as I know, I'm the first person to
set this into print). The Dremel collets (and the low end Fordom
collets) fit a bit loose and don't hold alignment well. If you wrap the
bottom (straight part) of the collet with teflon tape where it enters
the dremmel, until it fits snug, you will get a dremel that runs smooth
and true. If you're running a Fordom or other large flex shaft machine
and you are not using a $160 precision head you can get the same amazing
results on the low cost collet heads. Rewrap the collets after changing
collets 6 or 8 times or the tape gets "weird". If you leave the 1/8 or
3/32 collet in all the time, this isn't a problem.
Draw the tool perpendicular to the difection of rotation, and you get
nice cuts. This is hard to explain. Get the Graham book, it's worth it.
Avoid cheap diamond bits. A 20 piece assortment of "economy bits" that
run rough, peal out, or cut hot, slow, and rough is no bargain. Three
good bits from Crystalite or Eurotool at the price of 20 cheap ones is
the real deal. Start with a single, good 1/8 inch ball bit.
Avoid anything with a 1/16 shaft. You get better stability and working
distance from 3/32 or 1/8 inch.
Have fun.
Eventually you may suffer a respiratory illness akin to pneumoconiosis or
silicosis if you inhale enough, but the absence of crystalline particles
means that the carcinogens are not present, like in silica.
When the particles are in the lungs, the body fluids are likely to attack
them, which is why lead glass dust is potentially toxic. There are not
likely to be broken bonds on the surface, as they will all have been
hydrated before they get inside you. The glass is more likely to behave as
alkaline than acid, as the sodium, potassium or calcium ions are leached
out.
The advice about the respirator is good. The rest is unfounded in my
opinion. Sorry Joe, but ask a glass industry environmental health specialist
if you want a second opinion. look at http://www.britglass.co.uk for an
authoritative source of information. I have just come off their Environment
& Energy Committee.
