RE: DIY Mini Glass Vacuum Chamber
Only just spotted your stuff, very cool!
Do you suppose a dremel with a sanding tip would be a good way to rough up the glass before drilling the hole so that the regular drill bit doesn't slide around as much? Or would this lead to cracking?
Thanks, I found an easier way to hold the drill bit in place. Just get a cup, cut it in half, then tape it together. Next use the drill bit to drill a hole in the center using the concave side. Tape the outside edges for support and boom. Drill Guide.
The crack in the glass is on the inside, I kinda put too much pressure on it and it cracked through. I was kinda inpatient lol, I literally just made this after I read your comment, and was eager to test it out.
