I just read this article in BYO the other night, the process sounded like a PITA

We were installing a glass ledge on SS posts above our kitchen peninsula, and I went to the local glass shop to see what they'd charge to drill 8 tiny holes for mounting. $250. We ended up using super-strength glass tape.

And these were maybe 1/4" holes, in glass that's flat and more robust than a carboy. I imagine that if you took your carboy into a glass shop and asked them to drill a 1-2" hole in it, they'd laugh at you. "Sure buddy, we can try, but I can almost guarantee you we'll crack it". Drilling glass is a fools errand in most applications, and even worse in a situation like this where there's pressure exerted on it at all times, and it's curved.

I'd even be skeptical that many glass shops have a diamond bit that large in the first place...

If you decide to drill your glass carboy, I would avoid using a center punch to make a starter divot. Glass is very hard to dent.

Go to your local fish aquarium store and ask them if they could drill it for you. Holes are drilled in the back of the tank for an overflow. You dont actually drill the glass, you are actually grinding a ring into it. Having holes drilled into tanks usually cost about 20.00 each. So that being said, I think it would be cheaper to buy a carboy with the hole already installed.

I would think it would also make the carboy less structurally sound. As hard as I have set some of mine down on occasion I bet if I had drilled them they might not be with me now.

I've seen a few glass implements with spigots (for milk), but never one one that was not cast/blown into the glass at it's creation. IMNSEO, for a stable bottle you'd be looking at a cut, polish, and re-glaze (melt) all of which carry significant risk of breakage.

I've seen it written as PETE and PET.

Quote:
Polyethylene terephthalate (aka PET, PETE or the obsolete PETP or PET-P) is a thermoplastic polymer resin of the polyester family and is used in synthetic fibers; beverage, food and other liquid containers; thermoforming applications; and engineering resins often in combination with glass fiber. It is one of the most important raw materials used in man-made fibers.

Depending on its processing and thermal history, it may exist both as an amorphous (transparent) and as a semi-crystalline (opaque and white) material. Its monomer can be synthesized by the esterification reaction between terephthalic acid and ethylene glycol with water as a byproduct, or the transesterification reaction between ethylene glycol and dimethyl terephthalate with methanol as a byproduct. Polymerization is through a polycondensation reaction of the monomers (done immediately after esterification/transesterification) with ethylene glycol as the byproduct (the ethylene glycol is recycled in production).

The majority of the world's PET production is for synthetic fibers (in excess of 60%) with bottle production accounting for around 30% of global demand. In discussing textile applications, PET is generally referred to as simply "polyester" while "PET" is used most often to refer to packaging applications.

It is manufactured under trade names Arnite, Impet and Rynite, Ertalyte, Hostaphan, Melinex and Mylar films, and Dacron, Diolen, Terylene & Trevira fibers. [1]

They make these really cool racking canes that are rumored to lessen the risk of destroying glass carboys (please read being humours not smartarse) Really, the better bottles are the better option in this case. Why risk it on a 20.00 piece of glass.

OK, ya'll beat me to death on this one. I see the light. Just thought there was at least one crazy person out there that tried this.
