Techniques
Zero a Circular Saw Bevel
Checking the blade against a square for light, then adjusting the bevel stop's set screw so zero on the gauge means square to the base.
Sharpen a Shovel
Restoring a digging edge with a metal file at 30–45 degrees — enough bite to enter hard ground, deliberately short of razor sharp.
Miter Saw Square Calibration
Checking a miter saw against an accurate framing square and re-squaring its fence and stops so 90 actually means 90.
Make Paint Rollers Last
Getting more than one session out of a roller cover — washing and drying it for reuse, or keeping it loaded and sealed in a bag between coats.
Paintbrush Cleaning
A bucket-rim soaking rig plus the spread, pump, and comb routine.
Dress a Glazed Diamond Blade
Restoring a slow-cutting diamond blade by grinding off its glazed surface layer.
