Table Saw

A table saw is exactly what it sounds like: a circular blade poking up through a table, spun by a motor most people never think about until it stops working. Unglamorous as that is, it's the tool most shops get built around — ripping boards to width, crosscutting to length, breaking down sheet goods, and, with the right jig, doing a surprising amount of joinery too. Treat the blade with the respect it demands and it's the most productive machine in the room; get casual with it and it will not go well for you. Somewhere in between is the goal.

Key Parts

• Blade and arbor — the spinning cutting disc and the shaft it rides on; blade height and, on most saws, tilt angle are both adjustable.
• Rip fence — a guide running parallel to the blade, for cutting a consistent width down a board's length.
• Miter gauge / crosscut sled — guides riding in the table's slots, for square or angled cuts across a board.
• Blade guard and riving knife — the parts standing between the blade and a very bad afternoon, shielding the blade and keeping the workpiece from pinching it and kicking back.

Common Blade Kerf

Most table saw blades cut a kerf somewhere between 3/32" (thin-kerf) and 1/8" (full-kerf) — see Kerf for why that sliver of missing material matters once you're planning real cuts. The Board Foot Calculator and any serious cutlist both need to account for it between every pass.

Safety

Kickback — the workpiece getting thrown back at the operator, suddenly and with real force — is the table saw's signature hazard, and it's the entire reason the rip fence, riving knife, and blade guard exist. Never stand directly in line with the blade, always use a push stick on narrow rip cuts, and never pull a safety guard off without a genuinely good reason and a plan for how you're compensating for its absence.
