Cutting glass for tank

[Cobystolz]

I have a huge piece of glass I got for free and would like to make a frag tank out of it. The dimensions would hopefully be 47x23x12 inches. How would I cut that big of pieces of glass? It’s 1/4 inch glass. Also will I need any braces of any kind?

You will also need to bracing. You might also want to polish the edges. Glass is sharp.

Thanks, it’s not so much the thickness of it I’m worried about but that fact I’m gonna be cutting a five foot long piece of it

I made my sump out of a couple of old pieces of window glass. The longer cuts seemed to be easier. I made sure the cut / etch went all the way to the each edge of the pane and placed the cut line right at the edge of a table. Holding the table side piece down with weight and very lightly with clamps, I was able to snap a pretty straight line for all the sides and bottom pieces. The baffles work very well to support / brace the front to the back. I polished mine with good ol sand paper. Not something I have sitting out for the world to see. Just me.
Best of luck!

Ok thank you. I have cut glass before for sump baffles and a smaller tank it’s the 6x5 foot cut that sketches me out

So, use this at your own risk but I just cut a 1/4” thick piece of glass using a tile saw and a high quality diamond saw blade. Cut through it fairly effortlessly with a fairly clean cut.

How long was the cut?

Hey sorry I haven’t responded sooner I’m not getting notifications anymore.

I did three cuts at 17” but there’s no doubt I could have gone longer

That’s fine, I tried cutting it and I made the 5x6 foot piece break into like twenty pieces after all the failed cuts then it cracked up along it. Now I need to get rid of it and then I have another piece I can get but I’m gonna have someone else cut it

Sorry. Just saw this. I was going to say just take it somewhere. Won’t be very expensive to cut.

Agh sorry it didn’t work out. What did you end up using? a tile saw?

I ended up using a glass cutter that you use to score it

Okay I see. Sorry it didn’t work out. I also saw a thread on here where someone used a hand held tile saw to slice a 40b to make a shallow frag tank. If I find it I’ll share it with you.

PS I know you said you’re just going to have someone cut it but figured I’d share anyway
