We should have a write up regarding glass cutting somewhere.
If not, it goes on the to-do list!
I just made a template bat, covered it in rubber, and drill what ever hole sizing i need through it.
Its just your guide till you drill a channel deep enough anyways. As you know, the diamond tips dont have an arbour like the normal hole saws.
After that point its free hand consistent pressure with the water trickling so I can pump the drill bit to clear the cutting path.
On quality glass I tend to start and finish with a cordless drill with a loose grab setting, just a habit really, but saves that freakish crack scenario with the torque from a power drill. Simple, and works for me.
Strip of duc tape is handy to hold your glass piece in place on the other side, as long as you dont drill it as well, it allows for removal of the core with ease. Plus a towel as rocker mentions, as your safety net.
Just watch when you pick it up &/or shake it, small shards and all.
I personally differ from
rockerpeller regarding drilling the inside first. For me, I'm lazy and drill normally till I'm through
, then a quick hit with sand paper grades to give me the finish I want.
A bulk head is usually plugging the hole anyway, so i reserve the anal retentiveness for other aspects instead.
