Man I feel that. My first week on the job I was dimensioning everything off the nearest wall edge like some kind of caveman and my lead just stared at me for a solid five seconds before he showed me the grid trick. Felt like he was holding back laughter the whole time. Now I look back at those old drawings and wonder how I wasn't fired for making everyone redo their layouts around my wall-based nonsense.

Nah I'd push back on that. A blade swap is a bandaid, not a fix. If your saw's out by 2 degrees on compound cuts, that's a mechanical issue, not a blade wobble thing. Did you actually check the detents with a decent square or are you guessing?

Honestly, is it possible the foam was just a bad batch or way past its date? I've had canned foam crap out on me before when it was stored in a cold garage, and it never cured right either.

Right, because nothing says "relaxing weekend" like watching your lumber shrink faster than a wool sweater in a hot dryer.

Reminds me of the time I tried to save time by cutting through a meadow and ended up in waist-deep mud.
