well what we did was mark the acrylic on both sides with a dry erase marker and heat the interior side to fairly hot with a torch, then put a 2x6 where we wanted the bend and flipped it all over and heated the side super hot that was going to be stretched. worked well except my dad got the torch a little close to my fingers a couple of times
lol It actually worked a lot easier than i thought.
i am adding a picture of the beginning of my tank room. there are 8 10 inch bois d'arc posts 48" apart. there will be 48" added on the close end but only using 6"x6" posts. the double window will be removed and the tank will sit in that space so it can be viewed while eating. the single window will be left there except we are going to take the outside storm window off. that is my bdroom. i will be able to see the tank 24/7 then. :P
this last weekend we put up the walls, roofing, and flooring. we used 1 1/8" plywood for the walls and floor. 6" worth of R-19 insulation all the way around. there are 4 circuits going to the room from the breaker box.
i am going to try and find a thermostatically controlled window unit to control the temp in that small of a room. gonna try and keep it 80-82 degrees year round.
