    A friend of mine bought a DIY sump kit off Amazon and then tried to make a DIY overflow out of PVC pipe. To say the least, it was a serious headache of constant fine tuning to keep it running. So one week I decided to make him a hang-on the back overflow.

    Very nice, how do you cut the acrylic? Laser cutter?

    Thanks!
    Initial pieces are sized on a 10" tablesaw using a 60 - 80 tooth triple-chip carbide blade. All edges to glued are trimmed with a fence and router. After gluing, the remaining saw cut edges are trimmed with a flush trim router bit (router bit with bearing on top). I chose not to flame polish, because it actually stresses the acrylic and can ultimately lead to crazing (stress cracks).

    I could use a friend that can work acrylic. :p

    Man I need to carve out some space to set up routing table. I've been trying to trim route stuff by hand and it never turn out well lol.

    I could probably help, or at least give you some advice to what's going wrong.

    I'm assuming you have to have an external pump to keep it primed?

    For the teeth part, did you run a few cut each on the table saw? How did you make the inner edge clean.

    For the teeth I used a 1/4" dado. How I made it clean? Lots of practice.

    Looks crazy nice, very impressed! Is it a glass tank? Otherwise why not drill it.

    So how exactly does it get water up and over the edge? I know the thing on top was referenced but how does it work?
