I am going to have to cut about 2" off the end of my 1/2" thick plate glass, the total panel is 8' long and 30" tall and I will be cutting the 30" tall part. This is going to be a viewing panel for my plywood tank so the cut doesn't have to be perfect. If I were cutting a larger section I would be more comfortable scoring the glass and snapping it, I know it will be very hard to take 2" off a 8' long piece this way. I have heard others using a small hand wet saw for tile. Any suggestions are helpful and remember it doesn't have to be perfect
