Andrew Dwyer Posted December 16, 2019 Share Posted December 16, 2019 Soo, I have a small glass shelf in a niche in my bathroom: I would like to add another further up but the gap is too small, can I grind off a mm or two or will it shatter ?? I have some discs that I used on ceramic and they worked well. TIA Andy Link to comment Share on other sites More sharing options...
eyecatcher Posted December 16, 2019 Share Posted December 16, 2019 Since you have nothing under that shelf why dont you just lower that one. Why make things complicated Link to comment Share on other sites More sharing options...
CGW Posted December 16, 2019 Share Posted December 16, 2019 I wouldn't use a disc, the glass is "tempered" no saying how it will react, belt sander "may" work? but risky. Wear PPE, lots of it Link to comment Share on other sites More sharing options...
VocalNeal Posted December 16, 2019 Share Posted December 16, 2019 Where does the extra shelf come from? You have a matching twin? I think I would take a template to a glass shop and get one made the correct size. Link to comment Share on other sites More sharing options...

I bought 2 ( the same ) to go in the niche but the niche tapers slightly and I didn’t think I could grind it so I put it in another bathroom. Now I’m thinking ???? “ wish I had another shelf in that niche “ hence my question , and if it can be done I’ll buy another. Link to comment Share on other sites More sharing options...

worgeordie Posted December 16, 2019 Share Posted December 16, 2019 You are not cutting it, so slowly try and sand the extra off, put some tape on it in case it shatters. regards Worgeordie Link to comment Share on other sites More sharing options...
VocalNeal Posted December 16, 2019 Share Posted December 16, 2019 It is the surface that holds it all together. You should be able to grind/file the edges. BUT I wouldn't use a grinding disc that cuts up or down onto the surface. I think a belt sand that cuts into an edge would be OK? Dremel with a diamond bit? Again cutting along the edge not down onto the surface No direct experience just thinking about the physics. Link to comment Share on other sites More sharing options...

They are virtually synonymous. The tempering process toughens the glass. ???? also TSGC does not agree with you ???? Link to comment Share on other sites More sharing options...

Denim Posted December 16, 2019 Share Posted December 16, 2019 If you put the second shelf on the tile grout line it might be easier to grind out the grout line than risk damaging the glass. Link to comment Share on other sites More sharing options...
bankruatsteve Posted December 16, 2019 Share Posted December 16, 2019 You might try placing in at angle and then carefully tapping with a rubber mallet until it goes into position. That might crunch the tile a bit or break the glass ???? but grinding or trying to cut is not likely to work out well anyway. Link to comment Share on other sites More sharing options...

Unfortunately the lower grout line is too low and the higher too high ☹️ Ideally it needs to be half way down the tile as the lower shelf. Link to comment Share on other sites More sharing options...

Andrew Dwyer Posted January 3, 2020 Author Share Posted January 3, 2020 Well, just to tidy this thread up I bit the bullet and bought another shelf ( 500 baht ). I wrapped it in an old sheet with only the end showing, touched on lightly and removed the minimum necessary, it took me a couple of goes but did work. As you can see the out of square of the tiling caused the problem. I used a regular polishing wheel in a 4” grinder. If it had been a lot to take off I would have probably looked into buying a piece to size. Link to comment Share on other sites More sharing options...
