Wait, you chipped concrete off the float itself?

Tilting the laptop is smart, but those short bursts can still push dust around inside. You really want to keep the can moving while you spray. Opening it up is still the only sure way to get it all out.

Checklists are a lifesaver. We had a guy forget to check flashing on a roof edge once. Whole section leaked after a rainstorm, cost us a full day to tear out and redo. Now the checklist is the first thing they see on the work order. It sticks in your brain better when it's right there in front of you.

That 4-inch level story reminds me of a guy who tried to cut baseboard with a hacksaw.

My friend Sarah watched a potter in North Carolina adjust his wheel speed while pulling a handle. He slowed it way down for the last inch of the pull, almost to a stop. She tried it and said it completely stopped her handles from getting that wobbly, weak point at the base. Just that tiny change in timing fixed it.
