Drilling acrylic
Just wondering how difficult it is to drill acrylic and what type of bit do you use? I want to drill for a bulkhead through the side of my sump for the drain line, it takes up too much realestate in the sump. I think my sump was originally supposed to have a bulhead in the side of it. Also how high in relation to the first baffle do i put the hole?

You'll probably find a hole saw works best. Acrylic is quite resilient and drills quite easily. It also works well if you start the hole on one side and finish from the other to keep the hole clean.

A hole saw works just fine. Drilling cast acrylic is very easy and doesn't require any special procedure, extruded however tends to melt and could jam up the bit which could result in a crack. For extruded a little water to keep the material cool is a good idea and a little finesse goes a long way
