Repeat Cuts Without Re-Measuring
Cutting a stack of pieces to one length from a single measurement — a scribed line at the saw, or an end-hook template that guides the blade.
Keep a Circular-Saw Cut On Size by Cutting on the Correct Side of the Line
Technique: Cut on the Correct Side of a Layout Line
The Problem
A pencil line has width, and a saw blade removes even more material than the line as it cuts. A beginner who eyeballs which side of the line to run the blade gets it wrong about as often as right — and when the blade is on the wrong side, the finished piece comes out short by the width of the kerf, roughly 1/8 inch on most circular saws.
The Technique
- Mark your cut line, then decide which direction you'll push the saw across the board before you start cutting.
- If you're pushing the saw right to left, keep the blade on the left side of the line. If you're pushing left to right, keep it on the right side.
- Cut so the blade stays on the side of the line that's still visible past the motor housing and blade guard as you go — losing sight of the line partway through a cut is when it starts to wander.
Pick a direction, keep the blade on the matching side, and the piece comes out the size you marked instead of a kerf short.
Pro tip: This is a memory aid, not a law — some cuts call for splitting the line instead (leaving it just visible on both sides of the blade) or deliberately leaving extra material to trim to a scribed fit. Use the direction rule as your default for straight, to-size cuts, and depart from it on purpose when a cut calls for it.
