Hi Kev,

Cary is right, a good carbide blade will work, but make sure it's rated for non-ferrous metals - which usually means the blade has a negative rake angle on the teeth - IIRC, it's usually around -6 degrees.

If you're cutting the bottle in half through the diameter, I would prefer the miter saw, but if you're doing the length, the table saw is the way to go, I'd want to build a fixture to hold it, and then feed it through...

HTH
