I have an empty Stagg and an empty Thomas Handy bottle. I would like to cut them down and make drinking glasses out of them. Not tumblers but full size glasses for Ice tea/pop. An older friend who grew up in the early seventies once mentioned a device for such a purpose. I took it that it resembled a pipe or tubing cutter. Something that you clamp on the bottle for a square cut and rotate a cutting wheel around the circumference tightening the device as you cut through the glass.

I wonder If I can't simply use a chop-saw. With the straight sided BT Antique Collection bottles it should be easy enough to get a square cut. I would then need to file the cut so as to round the edges and create a safe lip.

Does anyone have any experience doing this with liquor or wine bottles?
