I have about a dozen tall vases in the perfect shape of a bong that I want to transform. Does anyone know how to make a perfect hole in curved glass without risk of shattering it? Thanks for the insight.
Yes, I do it is very easy...I used to make bongs out of glass when I was a kid.All you have to do is wrap duct tape around where your drilling the hole and in that area.Make sure theres a pretty good layer.THen drill the hole through the duct tape..THe glass will not shatter.Though do not take the ducttape off.
Peace
Vibration and heat are what make the glass crack get carbite or dimond tip and go slow a little lude ( WD-40, oil, water, anything to cool and lube) will help. fill with sand and/or use a sand filled bag to rest it on.
