Now since most of the sump is done, I need to drill it for a drain. This is the best way to drill acrylic, with a piece of backing to prevent chip, tear out, I use a piece of scrap 2x4 and a clamp, a good friend helps here if you don't have any clamps.
The wood is centered where the hole will be, just peeking out below the paper mask.
From the bottom up
The tool of choice, it's a 1/2" variable speed drill by Dewalt. I'm using Uniseals so I have the correct size hole saw installed
First hole
2nd hole
Both holes done
All done. Now to rout the tank and it'll be finished
