Click the above photo to download a plan for the infeed support.
The infeed support I designed and built is made from two pieces of hard maple 5/4 stock. The pieces are about 2 in. wide, although their width is not critical. A small, third piece of stock bolted to the horizontal member serves to clamp the support to the tablesaw. The point where the infeed support rests on the fence rail is drilled and tapped for nylon Allen screws. They can adjust the rail so that it is dead level with the saw. An adjustable nylon padded foot raises or lowers the other end of the rail so that it is even with the saw surface. The infeed leg is just long enough to support a 6-ft. 8-in. door unattended. When not needed, it is stored on wall hooks.
