I was telling a friend of mine that the plus side of being a woodworker is you can build cool stuff but the downside is we tend to overbuild it. Case in point, i went to hone depot to get lumber for a sandbox and they had 2/12 rough sawn redwood board that were almost the same price as pressure treated.
My fore plane removed the fuzz and my spoke shave smoothed the chipped edges. Then I used percussion right angles and a half dozen clamps with 10 outdoor grade pocket screws and gorilla glue in each corner.
Square sandbox unfortunately showed that the yard edging was not.
Side note, my oldest asked if a Gorilla handed me the glue like on TV.
