In my shop, I prefer to cut workpieces to length at the table saw. When I need to make multiple parts, I often use a block on my rip fence as a stop. When a project called for parts that were longer than my rip fence allowed, I built the fixture shown above. Saw Extension. My fixture consists of an arm with a T-track. A sliding stop block fits in the T-track and is held in place with a knob. To support the end of the extension, I added a leg on a hinge. The entire fixture is attached to the saw using a pair of clamps and can quickly be removed when it’s not in use.
Using the stop block is pretty simple. I use a tape measure to set the stop block in the correct position and lock it in place. Then, I can make my cut by sliding the workpiece against the stop block. If I need to remove the stop block for any reason, it simply slides off the end of the T-track.
