Shave a Hair Off a Cut
Registering a workpiece against a stopped miter saw blade so the cut removes a few thousandths instead of a full kerf — the way to close a joint that's barely long.
Trim
Baseboard, casing, and molding: coping, mitering, scribing, and nailing so the joints stay closed.

Techniques
Miter Test Blocks
Measuring between mitered long points with a pair of known-length test blocks — a clean tape pull plus constants instead of knife-edge reads.
Razor-Blade Point Transfer
Sticking a razor blade at a layout point so the mark exists in space and can be registered from the workpiece's other face.
Relief Cuts for Wavy Walls
Shallow kerfs across the back of a trim board that let it flex to follow a wall's contours.
Hang a Pre-Hung Door
Setting a factory-hung door plumb with an even reveal — the standard prehung sequence, the split-jamb variant, and the long-screw trick that stops heavy doors sagging.
Bend Aluminum Trim Coil
Folding trim coil to a crisp straight line in place — a light knife score and a block instead of a brake.
Scribing
Transferring an irregular surface onto a workpiece so it fits tight against it — baseboard to a wavy floor, a slab to a boulder, a board to rough stone — plus the rules that apply whatever you're fitting.
Free Recessed Trim With an Anchor
Driving a concrete anchor into a stop-drilled hole to jack recessed trim proud enough for a bar, instead of crushing the siding edge.
Molding Returns
Closing the exposed end of a run of molding — shoe, baseboard, casing — with a small glued miter return so the profile wraps back to the wall instead of showing a cut end.
Miter Saw Zero-Clearance Base
A sacrificial sole on the miter saw bed whose kerf shows exactly where the blade lands and backs up the cut.
Base Stock Gauge Block
A 10-inch trim offcut used as corner measuring block, square check, and notepad.
Brad Nail Deflection Control
Orienting the nail's chisel point so deflected brads skip along the panel, not out the face.
Caulk vs. Filler
Caulk for change-of-plane joints, rigid filler for flat seams.
Corner Board Details
Planning exterior trim junctions so corner boards finish clean.
Tighten Inside Miters
A shim behind the base that rocks a gapping miter closed.
Trim Out a Window
Jamb box first, shimmed square, then mitered casing.
Angle Finder Miter Formula
Turning a digital angle finder's corner reading into the right miter setting: subtract from 180, then divide by two.
Run Casing Over Proud Drywall
Scoring and breaking out the drywall behind the casing's footprint so trim sits tight to the jamb, with the relief hidden.
Chalk-Lining Finish Fascia
Snapping a two-end chalk line so finish fascia installs dead straight over imperfect framing.
Equal Panel Spacing
Stacking all the panels at one end, measuring the single leftover space, and dividing once — then walking a spacer block down the wall.
Offset-Thickness Accent Wall
Building the grid from three stock thicknesses so every joint lands stepped and caulkable instead of flush and fitted — a third of the build time.
Window Trim Layout Jig
A notched offcut that hooks the stool horn and marks apron and header lines identically on every window.
Miter Saw Angles Past 45°
Jigs and setups for cuts steeper than the saw will swing.
Chalk-Tinted Compound Repairs
Tinting setting-type joint compound with chalk so fills stay visible while you work and sand.
Preacher Block Line Transfer
A scrap jig that saddles a board and transfers a mating surface's line onto the face you cut from.
Zero-Clearance Inserts
Backing up the cut line so wood fibers can't tear out where the blade exits.
