Does anyone have a successful method for drilling or otherwise creating a lighting hole in straight sided globe. I have a Prentiss Wabers L46 that has no lighting holes in the frame. The original (missing) globe had a lighting hole. A Coleman 220 lantern globe will fit but I need to make a hole in it. Any suggestions appreciated. Reese
@cottage hill bill Tough call Reese. Over on Classic Pressure Lamps I’ve read posts of cutting around a circumference with a diamond impregnated wheel in a Dremel but nothing on drilling a hole - in a curved surface adds to the challenge. I guess my approach would be to drill a small hole - a suitable bit? - and enlarging it by passes around the circumference with a diamond-impregnated cutter of a marginally smaller diameter than the original hole. I winced as I wrote that! I hope someone comes up with a genius solution. John
@cottage hill bill I’ve done it on a bog standard Coleman globe. Water over the cut all the time, careful, careful, careful, and expect failure, so only use a glass you can replace. There’s a bit written on this over at CCS, as John has said. I’ve not “perfected” the technique. Cheers Tony
I’ve tried drilling in glass a couple of times - this is what have worked for me at least: As mentioned above you need: - PATIENCE - Either special glass cutting drills or a fresh and sharp(!) concrete drill bit (I prefer the latter up to around 8mm. The larger the drill - the more delicate it becomes when youre juuuust about getting through the glass(!) - Gaffa tape - Playdough/Clay or similar - water - Patience(!) - Practice on an affordable piece of glass. 1) Choose your drill bit (Special/Concrete - Some prefer the special ones - I prefer a fresh sharp(!) concrete drill bit. 2) Put some Gaffa Tape on where you want to drill. 3) Carefully with very little pressure make a small “mark” in the glass so your drill doesn’t slide all over the glass - no hurry and very little pressure while drilling - let the drill take its time. 4) After that, remove the Tape - and make a ring of playdough/clay to keep the water always on the spot - better more than less water inside that little pool. 5) Continue drilling with very little pressure and very much patience - especially when you’re just about breaking through the glass - don’t go to slow on the speed! - this is the most critical point.
Nice work with the drill technique . Tape it up and use and abrasive blaster I have cut some holes in glass that way . Erodes the glass very quickly Make sure you cover the offside glass unless you want it frosted . WR
