Building a Sump

[brizzo]

What type of acrylic did you buy, and how thick is it?

I don't want to sound like the doom sayer, but I think you're going to need more tools to build a sump of that size. Most saw blades are going to leave an 1/8" kerf, and would give you a much better finish to work with. If you have a router, and can build a small router table and fence you will be golden!! It's not actually that hard to build. 6mm+ acrylic for a sump that size isn't even practical to score and snap..
