Tips for drilling a Square Glass Bottle
We received an email from one of our visitors a while ago titled “Drilling”.
Hi, I’ve made a successful lamp out of a wine bottle but have run into problems drilling on square bottles. I’ve cracked 3 Jack Daniels bottles and a Crown Royal. They are flat and no matter how carefull I am, they crack! Any suggestions? Julie
To tell the truth, Nick and I were a little bit stumped by this question. You would think drilling into a square bottle would be much easier than drilling into a rounded surface.
We sent her the following reply:
We’ve been thinking about your problem for awhile and really couldn’t come up with a definitive answer.
Here are a couple things to look at though:
- Have you drilled a few bottles with the drill bit your using? It may just be dull. I ran into this problem, and didn’t realize that I was over compensating by pushing harder to make it drill. (broke a few myself)
- If your drill bit is still fairly new then you might want to look at where your drilling the hole on the bottle. I usually come up about an inch from the bottom. The base is sturdy and usually has a thicker glass that will compensate for drilling in the side.
- If your drill bit is getting really hot during this process you might want to put a ring around where it is that your drilling and put water inside. I tried this with ‘Play-Do’ once, and the water just leaked around the edge. A clay ring or plumbers putty should do the trick. Keep it in a Zip-loc baggie and you can use it over and over again for all the bottle that you drill.
I’ve drilled a few square Jack Daniels bottles before myself and never really thought about the flat surface verses the round. Once you’ve made your mark on the bottle it shouldn’t matter and should still drill the same.
Hope this helps and don’t give up,
Nick & Silke
We were very happy when two weeks later we received another email from Julie with pictures of her finished square Jack Daniels bottles with lights.
