A proper fence on a table saw should be strong, very straight, and be able to be locked into any position parallel to the saw blade. Many homemade fences are built using square tubing and angle iron with a cutting torch and a welder. However, a very capable fence can be built using a pipe clamp and some plywood, with some basic tools. This fence is strong, can be adapted to nearly any table saw, and locks tightly into place wherever you need it.
Measure the distance from the front edge to the rear edge of the saw table.
Cut two strips of 1.8 cm (3/4 inch) plywood at 10 cm (4 inches) by the length of the saw table measured in the previous step. Cut an additional two plywood strips at 6.2 cm (2 1/2 inches) wide by the same length, and two squares of plywood at 6.2 cm (2 1/2 inches) on each side.
Insert the spade bit into your power drill. Drill a 2.5 cm (1 inch) hole in the centre of each of the squares.
Assemble the four long strips of plywood into a 10 cm (4 inch) square tube by attaching the 10 cm (4 inch) strips to the 6.2 cm (2 1/2 inch) strips. Drive a 3.7 cm (1 1/2 inch) screw every few inches along each joint.
Insert one of the small plywood squares into each end of the tube. Attach with 3.7 cm (1 1/2 inch) screws.
Twist the hand crank end of the pipe clamp kit onto one of the threaded ends of the pipe.
Insert the open end of the pipe into one end of the tube, then through the opposite end. Attach the butt end of the pipe clamp to the open end of the pipe.
Place the fence assembly onto the table, with the hand crank end of the pipe clamp at the front. Position the front and rear jaws of the clamp so that they engage the table.
Adjust the angle of the fence so that it is parallel to the saw blade (front and back) at the desired location. Tighten the fence into place by turning the crank on the front clamp clockwise.
When working with power tools, always wear appropriate safety equipment, including safety glasses.
