>>I am planing on starting up a ball python breeding colony and I am going to attempt to breed a pair of BRB I have plans for the caging that I want but I am totally open to suggestions. it will be setup as one unit on casters it will have 8 seperate cages for balls and 2 seperate cages for the rainbows. on the exterior It can be no wider than 63"Lx18"Wx80"H. each ball python cage would be roughly 31"Lx18"Wx13"H. the 2 for the rainbows would be arround 62"Lx18"Wx13"H. I am looking for suggestions on building materials and heating. I am looking for the safest and most cost effective the front of it would probably have plexiglass and doors would swing to the side. I am just curious as to what everyone thinks.
Nit pick: dimensions are usually given in width, depth, and height. Technically, length and width are the same thing...
Building materials depend greatly on what sort of look you want, what tools you have available, and how much money you want to spend. In general, I suggest building with plywood. It's more expensive than melamine, but it's also stronger and I worry about formaldehyde out-gassing when you have a heat source in contact with melamine (e.g. heat tape against a melamine rack). If you don't want to pay for furniture-grade ply, you can always buy the cheaper stuff, fill the voids and knots with wood putty, then paint it. Or, if you're not going to have your heat source heating the wood (e.g. radiant heat panels), go ahead and use melamine (though in the sizes you want, it will start to get extremely heavy).
For ball pythons, I really like Markus Jayne's rack design, but it sounds like you're looking for something that looks a bit better? For the BRBs, you might check Greg Maxwell's Caging Page. Construction techniques are a bit more complex than they need to be (I'd use pocket holes and avoid all the clamping), but the idea of sealing the sides with waterproof contact paper is interesting.
Tell us more about what tools you have available and how much you're willing to spend and we can probably give you a better idea of how to build stuff...
