The Biesemeyer table saw fence is a T-style fence that glides on front and rear rails across the top of a table saw. The fence actually only locks onto the front rail, but the T-style design is sturdy and accurate to 1/64 inch. Developed by Bill Biesemeyer in the late 1970s, the Biesemeyer fence is now exclusively available on Delta table saws. However, you can install a Biesemeyer table saw fence on nearly any type of hybrid, contractor or cabinet table saw.
Measure the width of your table saw's table, from left to right (while standing in front of the saw).
Cut both the rectangular tubing and the angle iron to the same length as measured in the previous step with a hacksaw.
Align the section of rectangular tubing with the front edge of the table saw (with the 2-inch edge against the edge of the table. The top, 3-inch side should be down 1/2 inch from the top of the table. Drill four matching mounting holes in the 2-inch side of the tubing as well as in the front edge of the saw table, and mount the tubing to the table with bolts, lock washers and nuts.
Repeat the previous step with the angle iron on the back edge of the saw table. The protruding portion of the L-bracket should be beneath the edge flush with the table.
Place the Biesemeyer onto the table top, with the locking mechanism straddling the rectangular tubing in the front of the saw.
Adjust the positioning of the front tubing and rear angle iron so that the Biesemeyer fence can be slid left or right along the entire face of the table saw. The fence should glide evenly just a hair's width above the surface of the table. Securely tighten all of the nuts and bolts with a wrench or socket set once the two rails are in the proper position.
Align one edge of the Biesemeyer fence with the edge of one of the mitre slots. The edge of the fence should be perfectly parallel with the mitre slot. If the rear of the fence is angled slightly to the left, Tighten the left adjustment screw (found on the back side of the locking mechanism where it meets the front tubing) with an Allen wrench. If the fence is angled to the right, tighten the right adjustment screw.
Raise the blade, adjust the position of the Biesemeyer fence, and rip a board through the table saw. Pay special attention to whether the board binds or if a gap appears between the wood and the fence after the board passes the blade. If either problem occurs, check the fence against the mitre slot again.
