Outfeed Support

With the saw in place, I added an outfeed support to "catch" long workpieces when completing a cut. It consists of three parts: a wood frame, a long crossbar, and a pair of arms to attach it to the cabinet.

To ensure that the workpiece slides smoothly off the saw table onto the outfeed support, the top of the crossbar needs to be at the same height as the saw table.

frame. So when building the frame, the first step is to determine the height of the uprights (W), see Fig. 8. To do tins, measure the distance from the bottom of the cabinet to the top of the saw table and subtract the overall thickness of the crossbar (134").

The uprights are held together with two rails (X). One fits in rabbets cut in the top ends of the uprights. And the other into dadoes cut near the bottom.

crossbar. Once the frame is screwed together, the crossbar is made by gluing up a top (Y) made of "two-by" material and a Masonite ewer (Z). By cutting a wide bevel in the cover (Fig. 8a), even thin workpieces that tend to sag-will slip easily onto the crossbar.

into T-nuts installed in the uprights and back stiles locks the outfeed support in place.

Finally, after installing level-ers on the uprights, I added two T-nuts to each upright for compact storage, see photo below. &

Miter Gauge. A block with a notch cut in it holds the miter gauge. And scraps of Masonite keep it from slipping off.

Rip Fence. To hold the rip fence, these brackets have grooves formed by gluing strips of Masonite to a wood block.
