So, I figured out how to cut wine bottles by holding my glass cutter in my vice, which is turned sideways and towards the bench. I then also added a vertical and horizontal guide by nailing bits of wood onto the bench top. Here you can see the set up with a freshly scratched bottle.
Then I boil the bottles over the fire to heat them up, and then pour out the hot water, plunge them quickly into ice water for 5 seconds, pull out and give a tap with a piece of wood, and they break cleanly. Then it's just some time with the belt sander and then cleaning them up. Got so I did 7 $2 chuck bottles that turned out well. No more buying drinking glasses!
and yes, that is a mint julep on the rocks - we had left over humming bird food. what else am I supposed to to do with it??
