A Micro-Adjustment for the Saw Fence
This micro-adjustment fixture enables you to fine-tune the settings on a Biesemeyer-style tablesaw rip fence. The fixture consists of two main parts: a block that attaches to the cross piece of the rip fence and a clamp head that locks onto the front rail of the fence.
The adjusting device itself is a 6-in.-long, 1/2-in. carriage bolt with a wooden knob glued to its head with epoxy. The bolt runs through a slightly oversized hole in the clamp head and into a rod coupler that has been press-fit into the block. The length of the rod coupler, as opposed to a standard hex nut, helps prevent the adjusting bolt from binding as it is turned. The range of adjustment is about 1 in., more than enough for most applications.
To use the device, leave the fence-locking lever up, and then clamp the head to the fence. Twist the micro-adjustment knob as necessary to locate the fence where you want it. Then lock the fence in place with the regular locking lever. The whole setup works smoothly and is a pleasure to use.
