ACRYLIC HELP! how do I make an overflow wier?

[Mr E Wrasse]

Hey guys. I just picked up a 40g breeder from Petco ($40!!) to use as a frag tank. I am going to drill the back for a corner overflow box but I need to know how to cut out the wiers in the acrylic.
Also does anyone know where to buy corner overflow boxes (in case i get lazy)?

You can cut them with a jigsaw, table saw , router, or dremell with patience... Need help lmk... I can even make ya one for like 10$ plus shipping lol...;)

whenever I use my jigsaw or dremel on acrylic I always end up melting it. For straight cuts I always use my table saw with a plastic-cutting blade and that works great. I guess i could use the table saw and make 2 cuts with the blade for each wier. Whenever i do this kind of stuff i always want it to look clean, that's my main concern.
