i can help you with a wood frame screen design. but to do it right it takes a few weeks. my 24x36x48, is built around the largest plastic tub i could find. it cost about $80.00 american dollars. i would have built a alum screen setup but i dont like the oxidation water causes on alum and they are not very sturdy. on the other hand they are a lot lighter. my setup is about 43lb. bottom is poplar, rest of frame is built out of finish grade pine. both underwent marine sealing process. i have two diff screens one 8th" nylon mesh. second inside screen is .5" plastic screen. second screen is to keep his claws from snagging in .125" screen. top has .25" wire mesh so lights dont weaken or give of fumes. the drainage system works great i mist two times a day, 32oz. water each time. if you are interested i can make a layout, assembly and cut list for them. as far as tools all you will need, screw gun, screws,stapler(bostich heavy duty $16.00 at home depot.),.5" staples,utility knife and saw of some sort. if you choose alum screen you will need hack saw,spline roller,screw gun or hand driver,utility knife and possibly more. if you want to go furiture quality, i know a guy in sac that builds customs. but he is pricey.
