Man, you almost had it perfect with that $40 jig and then it goes and pulls a fast one on you by not having a depth stop... figures. I swear it's like these companies know exactly what to leave off just to make you upgrade to the $100 version. At least you didn't blow through the plywood and have to start over though, count your blessings on that one. For real though, paying forty bucks to save four hours of work is still a steal, even if you have to eyeball the depth like a caveman with a drill.

And once you factor in that annual fee to the break-even calculation, the timeline gets pushed way back, sometimes to the point where it's barely worth it lol. It's wild how those small charges change the whole picture when you actually run the numbers.

Ngl, Hank was right. Wetting that subgrade stops the dry dirt from sucking all the moisture out of your concrete.

Agree with @adam_hernandez completely. Results talk, everything else walks. Simple shift makes ALL the difference.

Skipping patch tests is just asking for trouble.
