A way to drill holes in glass

[Orchidtinkerer]

have you tried the sellotape trick at all waterwitchin to see if that makes it any easier?

You can do all you do but just place a peice of tape over the spot you are drilling before you start. It should make drilling easier and prevent cracking.

It is something plumbers do to avoid cracking tiles in bathrooms so if it works on bathroom tiles it shoud in theory work on glass bottles too.

I'm using the wood jig to avoid the drill skipping when getting the hole started, not to avoid cracking. I did try regular tape and painters tape for that purpose, but neither worked well, for me.

Tape is more for that same issue, skipping, not so much cracking. Most types of tile are much easier to drill than a rounded piece of glass, and I don't bother with tape. I've laid miles of tile... my dad was a plumber by trade, but also a fairly skilled mason and tiler.
