so i had taken apart a 55gal tank that a friend found on the side of the road. i used one of the front panels for a glass piece on my plywood bearded dragon cage, and i had the other sheets there stacked up. i decided to take a stab at cutting my own glass. the 12"x18" side panels would do perfect for my 16" tall baffle i needed for the refugium section. rather than wait for the glass place to get back to me i decided to google search on how to cut glass. i found this great article which lead me to the proper tools i needed. thankfully my family has a long history of carpenters so i have a plethora of tools. my grandfathers tool chest yielded a small cutting tool for glass. this link helped me get the pliers and such together: How to cut glass i then scored the glass, and put pressure on the side i wanted to break off. nearly 90% of the piece cracked perfect straight down the scored line. only a few fragments remained which i chiped away with another pair of pliers. all in all a success! i now have my baffle which i will silicone in when im done cleansing this 40gal tank. (been busy with some school related things) i also found enough plexi leftover to make my 9"x12" baffles for the skimmer/sump section. ill post pictures tomorrow of my endeavor. im quite tired now, and going to sleep.
