hi guys. just purchased http://www.grasscity.com/us_en/g-spot-tulip-bowl-chillum.html 14.5mm joint as my downstem for a glass bottle bong. i'm using a kraken rum botttle, which has vertical sides: i know there are loads of tips for glass drilling online, but none mention drilling at an angle for a stem. so, is it possible? or would it still work if drilled, sanded, and then bought a 14/15mm rubber grommet? or should i use a dremel to make an oval shape 14.5mm wide? basically, help! if someone could give me a play by play that would be great, because everything i've found so far tells me to drill perpendicular to the bottle surface! cheers
I've always wondered the same thing. I never got a dremel and diamond bit to do it instead i bought a bong . in theory you could drill and angled hole but it would take skill and patience.
