50 or more, go to a fishing store n see what they've got.
I've used the fishing line trick to remove emblems off of some of my cars and old nasty goobered on dealership plaques and it ALWAYS works if you give it enough heat and time.
all i had was the chisel and hammer or string. and i believe it was a mix of the bend and the angling i couldnt get a saw-like tension on the silicone and it got about 1mm and hour and that was not going to work. my heart dropped everytime i heard the cracking of the glass. but its totally gone and cleaned up now. tomorrow i put in a new moss wall and refill all fish look good still and hopefully becuase of the water drop my alfbnp start to breed if not oh well there all alive and well i cant ask for morewow, you're braver then I would have been in that situation. I was just thinking of score the inside with a glass cutter, or maybe drilling some holes near the edge, and then breaking it, and leaving the back/side still siliconed to the tank.
Good job though, that's pretty impressive.
I think the main reason the wire/line method didn't work is because it had too much area to cover, in addition to a bend.
thank you i was so scared every swing i dont think ill every be that lucky again. the point chisel helped so it broke where i wanted it. the back was the worse but when i got it all the way to the silicone i was able to just get a razor behind it and slice it out. when my tank clears up ill take a pic of it and post it on hereVery, very nice job on removing the overflow!!! You are much braver than me using a chisel and hammer.:icon_eek:
i tried the guitar string and it wasnt working. it was like trying to cut tree by pulling down the curve of the glass and the gap behind was to thin to get anything that could acually cut i think the wire works better on the corners of an aquarium then on this particular project.guitar or piano string.....just a thought but you got it taken care of already..
