It doesn't matter if the bottle is half full or half empty. With this bottle cutter you can make half a bottle thats all full, and half thats all empty..... everyone's happy
There was a nice instructable on how to make a glass bottle cutter that was made at tech shop (http://www.instructables.com/id/Want-to-cut-wine-bottles-Build-this-jig/). It was simple and easy to make, however it only allowed for one size cut unless you re-made the entire rig. Another that was adjustable but used wheels and was a bit complicated (http://www.instructables.com/id/Glass-Bottle-Cutter/). Since I wanted the bottoms cut off for a light project, and my daughter wanted a bottle glass to hold her paint brushes and had most of the materials laying around, I came up with this.
Made from simple materials and straight cuts, its easy to make and inexpensive.
Here is a link to the denatured alcohol lamp. I am planning on using this to heat the bottles after I score them.
