LF 4" diamond glass holesaw. Calgary

[Tigweldpro]

Well after calling around to some more glass shops I found one that will "try" to cut the hole @ 90$hr shop rate and if they break the piece I still pay the shop time and go home with broken glass. wow now that's customer service at its finest

Well who would have thought that an old dull starrett wood/metal holesaw and a handful of sand/water would grind through glass.... My $10 powerfist drill definitely paid for itself today. The hole is a bit oversized but I put a bead of silicone around the inside and the sock fits nice n tight.


Success has been achieved for $0

Wow, my hat is off to you. Can you please explain how you did that?

Interestingly (to me anyhow, lol) is that I'm sort of in the same boat. I want to build a sump insert to hold a filter sock or two but the larger size. I've been stuck at the "do I go glass or do I go acrylic for this" decision point for a couple weeks. I'd prefer glass, just .. "because".

Just go slow and let the sand go under the drill bit as often as possible?

yes build a playdoh or plumbers putty dam around the hole to hold sand/water. you need a 1/4" glass bit to make a pilot but you can get a set of small sizes for a few bux on fleabay. I used a cheap 1/2" electric drill but I think a drill press would work best. you don't want much pressure just enough to feel the sand rolling between the saw and glass. drill 1/3 of the way through from one side then flip it over so you don't get breakout on the bottom side. I used pool filter sand mostly quarts but if you could get a fist full of sandblasting grit it would probably work better. took me over an hour to grind my way through but whateves its a hobby.

I think unless you already have an old holesaw/sand/drill. buying the $50 one on amazon would be the best bet as you can resell/rent it out after. The hole size you want is 3 7/8" anyway my 4" was a bit big.

You can also go to crystal glass and have there "experts" break your glass and send you home with a $90 bill.
