Step 2 Preparing your frame

Step 1
This part is a little dangerous. Wear eye protection.

Break your bottle.

This will take multiple attempts and a little luck to do successfully.
Originally we intended to use a glass cutter to mark where we wanted the glass to break. That proved to be useless once was actually started hitting the bottle (plus its super hard to get a good score on a curved surface like this) so in the end we just gave the bottle a quick tap with the hammer, and the gods of chaos decided this was the shape we're using. So long as you have two open ends of glass to work with, you're good.
I prefer this "bar fight" shape for aesthetic reasons.
A tip from Shady180:
I've always had luck with cutting bottles by using a large metal hose clamp (available at any auto parts store) around the outside. Tighten the hose clamp snugly up against the side of the bottle then use a utility knife to score the glass along the upper edge of the hose clamp. The steel edge of the clamp serves as a nice straight line and prevents the knife slipping. After scoring, use a small hammer (tap hammer or peening hammer) to break the glass along the scored edge. Works great.

Now cover the sharp edges with electrical tape so you don't cut yourself.

 FYI, there's no need for the electrical tape. Glass is easily sanded to a smooth surface. This will make your "device" much less ghetto.

"Glass is easily sanded"......On what planet is the second hardest substance "easy to sand?"

[adamic_99]

On Earth. Try it.

[fly_boy_bc]

Simply not true. I am a glassblower AND a laboratory optician. I grind glass all day long and it takes DIAMOND grit to do it and it has to be under hundreds of pounds of pressure. No way you can call it "easy to sand". Easy to SCRATCH sure but to actually remove a noticeable amount of material? That is beyond most peoples abilities/tools. You can GRIND glass on a grinder fairly easily because of the speed. Sanding implies a hand process. Very difficult.

ROFL, what kind of glassblower/laboratory optician has a name fly_boy_bc?

[fly_boy_bc]

One who is a pilot.

[x3n0c1dal]

Good point, but a juvenile pilot born before recorded time?

[adamic_99]

Ok jeez. I'm basing this on personal experience. I bought an 18" x 18" x 0.5" piece of glass that I had cut. The edges were super sharp. So I took regular sandpaper and sanded the edges and low and behold, it smoothed them out pretty easily.

nothing against your choice in adult beverages, but would a beer bottle work well too? specifacally a certain british brewer with an unreal oatmeal stout or maybe a french canadian brew that uses a 750 ml bottle. Or do you use clear bottles that you may see whats going on inside the machine part. or for that matter, any wine bottle

I've been told this trick to cut bottles: 1) tightly tie a thick cord previously dipped in alcohol around the bottle 2) put the cord on fire 3) when the fire is over, plunge the bottle in a bucket of cold water. This results in a clean safe cut, with no chaos theory involved. ;)

I will have to try this and see if I am any good at it.

[mondaymonkey]

hmmmmmm that sounds smart. I'm going to experiment with that. I sometimes wash my herbal water pipe (Y'all know what im talkin bout) with alcohol to clean it... sometimes I light the alcohol to see fireshows... but now that I think of it rapid cooling could break it)
