John White, Fine Woodworking’s shop manager, dissects the jointer and explains its parts and how to tune it up. You’ll need feeler gauges, a small try square, and a good, short straightedge, plus a long straightedge to check for flatness. White takes you through four steps: adjusting the gibs, leveling the tables, squaring the fence, and setting the knives. He also explains how to level the tables with a shopmade test bar, how to fix a crooked fence, and how to replace a spring or jackscrew on a cutterhead.
