Default Circular Hole in a Bottle

I wish to cut a round disk out of several wine bottles. The bottle
has an etched figure I wish to remove for another purpose. I have a
virtually unlimited supply of these bottles and they have no value so
I can afford to make mistakes.

How should I go about cutting a 2 inch diameter disk out of a bottle?
I had thought to use a diamond blade on my Ziptool to cut out a
rectangle and then wet grind the removed piece.

A diamond hole saw may be a possibility, but they are EXPENSIVE.

What would you suggest?

Thanks, Eric

Where is the figure located on the bottle?

Assuming it is where labels are usually on bottles, use a glass cutter to
score a line above and below the area you wish to keep, then use a curved
rod to tap the area on the inside where the score marks were made. The
glass should fracture along the lines.

Now that you have a cylinder, score adjacent to the figure and another score
on the cylinder opposite the figure. Tap on the inside along the score
lines and the glass should fracture where scored. Grind the figure out of
the remaining chunk of glass.

they come up with this striped stuff.

Please post back on how you make it happen, and good luck.

I tried bottle cutting about 35 years ago - cheapie, but it worked.
Moved on to my next hobby, which was decoupage )

Lots of bottle cutters available, if you google:
http://www.sks-bottle.com/340c/fin175b.html

I would try a bottle cutter x2 on the bottle to remove a tubular section
with the desired figure. Then use straight glass cutter, with section
on a support, to score and remove the figure, Then, cutter and nippers
'til you get it fairly round. Sand or grind.

You can also use a nichrome wire heated to blood red (too hot or it'lll
stick to the glass), and rock the score line on the wire. Going back and
forth, stressing out the cool section with the hot wire, and it'll come
right apart.

I would take it to a glass shop and have them do it. I doubt they
would charge much. Call around and check them out. They could probably
do it for less money than it is going to cost you for a glass cutter.
Or, at least they can advise you better.

About 30 years ago my sister in law did something like what you are
doing, it would be funny if it was the same bottles. She cut the top
and bottom off the bottles forming a cylinder and then cut the design
from that in a rectangle. She nibbled it down as far as she could to
the right shape and then took it to a glass dealer for final polishing
and shaping. I believe hers was an oval. She made Christmas ornaments
of them.

OK- What are you guys cutting out of the bottles?g I've been
looking at the Frank's hot Sauce bottles for a while and trying to
figure out how I make use of their little embossed peppers.

On the 23oz bottles they are up too high to remain if I made bloody
Mary glasses out of the bottles.

A good first step would be to find out what type of glass you want to
cut. Not all bottles are the same. Those built to withstand pressure,
such as beer or champagne bottles, are often tempered and harder to cut
without unintentional breakage.

I'd be inclined to visit a glass shop, particularly one that does
stained glass.

The OP said, "wine bottles".

Hi Eric,

My suggestion is to go to your local Gem Club and ask them to use a rock saw
to saw the bottle. You should be able to roughly cut out the area you want
and then use their grinding wheels to shape it. Use a fine diamond wheel to
finish off the edges so they are not sharp.

I am familiar with this type of equipment and have used it several times to
cut bottles etc.

Here is a link to the Hervey Bay Gem & Mineral Club website.
http://tinyurl.com/hbgc4655
Click on "Club Photos" on the toolbar and then "Photos Around the Club"
You will see photos of the saws and grinding wheels to do the job.

Cheers,
Larry

bottles are never tempered. i doubt that they can be tempered, as that
requires heating both sides of the glass at the same time, then quickly
cooling both sides at the same time.

someone with a wet tile saw would be able to do the same thing. there's lots
more tilers than mineral clubs.

A 2" diamond core drill is about $50. It will do exactly what you
want. If that is too much for your budget, find a more inexpensive
hobby. Oragami comes to mind....

In that case, give a million bottles and a million rocks to a million
monkeys. One of them will break it correctly for your application.

Default Circular Hole in a Bottle

Been watching this, and had to chime in with some ideas.

I found about a dozen broken whisky bottles, but just the shoulder, neck,
and lip. They were 1889's and brown glass. Nothing special.

I made a jig for my diamond tile saw, and cut them diagonally, all equal,
with some shoulder left.

I then mounted them on dowels on a board, and filled the void with epoxy.
It is a fine looking hat rack.

If I was to do this, I would get a Dremel or equivalent and make a holder
for it. I would then make a cradle for the bottle, and then make a cradle
for the bottles. All of this would be adjustable for different sized
bottles. A follower and distance gauge would have to be figured out so as
to keep the Dremel wheel at a constant distance from the surface, and
vertical for a vertical cut. This would be a little tricky, as the cuvature
is going to change.

If you were going to use a core drill and just drill a hole in the bottle
from the side, essentially, you would have up to four separate contact and
pressure points, and just the right amount of pressure and lubrication would
be needed, or you have toast.

I think one could be made by a good machinist, and someone who is good at
math so that the bottle in the cradle turns true, and the Dremel keeps the
same distance from the bottle. I do think that just having one contact
pressure point would be better, and perhaps even diamond discs are available
for Dremel/Foredom/et al.

Keep us posted.

Steve

As an aside, who would WANT a bottle with a hole in it (aside from the
obvious one)?

drill it with the bottle submerged in a bucket so that it would be cooled by
the water. a core drill works by grinding, not cutting, so it doesn't matter
how many points it contacted the bottle.

I think one could be made by a good machinist, and someone who is good at
math so that the bottle in the cradle turns true, and the Dremel keeps the

During the 70's hobbyists were cutting bottles
to make glasses, vases, bowls, etc...

Tie heavy twine around the cut line.
Soak in lighter fluid, light, let burn,
then plunge into a bucket of cold water.

The bottle should part right at the string line.
Then use a Dremel tool to smooth the cut.

You've got lots of bottles...experiment !

I seem to recall that one could use nichrome wire
to do that, with better results. (Cleaner edge,
less cleanup.)
The wire is wrapped tightly around the bottle to
be cut. An isolation transformer drives
your Variac which powers the nichrome.
The wire creates a very localized strip of hot
glass. Dipping the bottle in water causes a
clean fracture at the heat line.

Grind the lip of the glass for a flat surface
and rounded corners.

Use all safety measures, like eye protection and
gloves!
