Build a Table Saw Outfeed Table

Plywood wants to tip. An eight-foot board wants to lever your workpiece into the blade. Every shop accident that starts with "I thought I could hold it" traces back to inadequate outfeed support. A proper outfeed table isn't a luxury—it's the difference between safe, accurate cuts and white-knuckle wrestling matches with dimensional lumber. The ideal outfeed table sits dead-level with your saw table, spans at least four feet behind the blade, and offers enough width to catch sheet goods as they exit the cut. You don't need fancy joinery or exotic hardwoods. What matters is a flat surface, solid construction, and the ability to adjust for your saw's exact height. This weekend project transforms how you work with full sheets and transforms your garage shop from cramped to capable.

  1. Measure Twice, Build Once. Measure from floor to the top surface of your table saw at multiple points—saws rarely sit perfectly level. Record the highest point. Decide on outfeed table dimensions based on your shop space, but aim for minimum 48 inches deep behind the blade and wide enough to support a half-sheet of plywood. Standard height will be your saw measurement minus ¾ inch for the plywood top.
  2. Cut Every Component Identical. Cut four legs from 2×4 lumber to your calculated height. Cut two long rails and two short rails to form the perimeter frame—use 2×4s for tables up to 6 feet, 2×6s for anything longer. The rails should create a rectangle that leaves about 2 inches of overhang when the plywood top is attached. Cut cross supports to span between the long rails every 24 inches.
  3. Build Square Foundation First. Attach the short rails between pairs of legs using 3-inch deck screws, two per connection, pre-drilling to prevent splits. Stand these two leg assemblies upright and connect them with the long rails, checking for square by measuring diagonals—they should match within 1/8 inch. Add cross supports between the long rails, screwing through the rails into the support ends.
  4. Lock Feet for Stability. Install either adjustable leveling feet or locking casters at each leg. For leveling feet, drill pilot holes and drive T-nuts into the bottom of each leg, then thread in furniture levelers. For casters, use heavy-duty swivel casters rated for at least 100 pounds each, attaching with lag bolts through the leg bottoms. If using casters, add 2 inches to your original height calculation.
  5. Secure the Work Surface. Cut your plywood sheet to final dimensions. Sand any rough edges that might catch workpieces. Center the plywood on the frame with even overhang on all sides, then attach with 1¼-inch screws every 8 inches around the perimeter and into each cross support. Countersink screws slightly below the surface—proud screw heads will scratch your work.
  6. Match Saw Height Exactly. Position the outfeed table behind your saw with about 1/8 inch gap. Lay a straightedge across from the saw table to the outfeed table. Adjust leveling feet or add shims under casters until the outfeed surface sits perfectly flush with the saw table across the entire width. Check both front corners and the center.
  7. Add Precision Without Obstruction. Rout channels parallel to the saw blade direction and install T-track aluminum extrusions for mounting stops and hold-downs. Alternatively, screw simple wooden stop blocks to the surface for repetitive cuts. Position any accessories to avoid interfering with the exit path of common sheet good dimensions.
  8. Prove Your Build Works. Run a full sheet of plywood through your saw, feeding it slowly and letting the outfeed table take the weight as it clears the blade. Listen for scraping sounds that indicate height mismatch. Make final adjustments to achieve smooth, drag-free travel. Mark the floor with tape to show the table's optimal position for future setup.
