Well that all depends on how close of friends you are with your local glass cutter ;) I know in my area, my glass shops won't touch anything if it is attached with the word "aquarium". However, I talked to him at great length and he told me that if I provide the glass, assume all responsibility for if the glass, and if it doesn't score/fracture right, its on me. My glass guys will cut and give me sanded edges for free as long as it is in their spare time. I usually throw them a few bones anyways. Note, most glass shops will probably tell you they don't have the equipment to cut 1/2" or thicker glass. there is a very specific snaping tool you must use to slowly crack the score. Its not easy, I've tried. Out of curiosity, I have scored a 6 foot piece in half, put a broom handle under the sore line and jumped on the darn thing. Nothing lol. (please do not try this as it is dangerous and dumb lol. I literally was just wondering how strong this glass actually is. So, I either cut it on my wet tile saw or take it to them to score and snap. If you want the edges polished, you will probably have to pay to have them ship it to a place who polishes the edges, and pay the per inch fee of something like 2 bux an inch or so. Also the glass must be darn near perfect, no scratches near the desired score line, no coralline, dirt, debris, silicone, etc, or else it will not score straight and likely fracture across the pane. Again, it is not easy, but if you can do it, you can build a sweet custom tank for peanuts. Well worth the try in my book. If you do, I would recommend the momentive black 100 series rtv to glue the new panes together. Not just hardware store grade silicone.
