In this video I demonstrate how to make a mini sandblaster/sandblasting cabinet, and use it for a surprisingly effective glass cutting method.
Using ordinary play sand and a bit of electrical tape it’s possible to cut complex shapes including tight curves and sharp inside corners into glass. Watch the video from NightHawkInLight for more info:
With the help of some electrical tape and paraffin wax, he shows how to cut a perfect helix shape out of a test tube. If you plan on trying to DIY, be sure to follow his recommended safety precautions.
Without a cabinet the sand gets everywhere. On every inch of your both, in every pocket, crease, and crevice. Really it makes a huge mess so do this outside. If you wear prescription glasses put a pair of goggles over them. The sand will etch/scratch everything it comes in contact with, including expensive prescription glasses./NightHawkInLight
