12/2023 - 01/2024: Time to build the stand. My plan was to build the stand (to make sure I could do it). Then order the tank. Tank lead time was about 6 weeks, which would give me enough time to figure out how to take down the wall and position the stand. So, I watched a bunch of You-tube videos and got my plan. I spent about 1 hour in Home Depot going through multiple piles of 2X4's to find straight-ish ones. Some of the 2X4's are so warped there would be no way to make an acceptable stand out of them. I started taking time to make sure everything was level and square (which my garage floor was definitely not)
Used #10 construction screws with pilot holes. I tried without pilot holes and it did not go well. The wood started to split
Wider space in the middle so I can easily slide in the sump.
Started to spackle and sand over the screw holes with wood filler
Added the bottom face for the sump and 1/2" plywood for the back
I got a little nervous there was nothing significant to take a shear load. So I added some diagonal supports (these were not in any video I watched)
Checked to make sure the sump fit - it was close. And I realized the overflow intake was on the opposite side than I thought. Good thing I didn't order the tank yet.
And now for the top sheet of 3/4" plywood. I used a combo of gorilla glue and wood glue. I some small shims in the corners to keep the top sheet very flat. The gorilla glue was used closer to the shims and the wood glue where the sheet was flat against the supports
And the finished stand before paint and cabinets - it came out pretty good and solid!
