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.
Aim a Laser Level Precisely by Setting It on a Longer Scrap Board
When a laser line keeps overshooting its mark as you nudge the level, set the level on a longer piece of scrap instead of the floor — pivoting the far end of the board moves the line a fraction of what moving the level itself does.
laser line won't line up, fine adjust laser level, laser keeps overshooting mark, rotate laser level slightly
The Problem
Rotating a laser level to land its line on a mark across the room is touchy: the smallest hand adjustment at the level swings the line past the mark, first one side, then the other.
The Technique
Set the level on a piece of scrap material longer than the level's own base — a length of board — and make your aim adjustments by pivoting the board, not the level.
The scrap works as a reduction lever. Nudging the far end of a long board rotates everything on it by a much smaller angle than pushing the level directly, so each touch moves the distant line a fraction as far — small enough corrections to walk the line onto the mark.
