Fixing The Fence

The fence is easily the most frequently used router-table guidance system. You use it to direct the movement of the workpiece to the bit. You use it to position the cut. and sometimes to control how deep the cut is or what its profile will be.

The fence itself can be a straight, Hat board, a sophisticated, multipan construction, or something in between. (See tl ie el laptei "Router Table Accessories" for fence designs.) It's not unlikely that the more you use your router table, the more special-purpose fences you'll end up with

Typically, the fence is clamped in place, though Fred's split fence has integral clamps that are secured with easy-on-thc-fingers plastic wing nuts. You can use whatever clamps are available, except Quick-Grip clamps. The Quick-Grip clamps are easy to apply, but even when tightened to the maximum, their rubbery jaws don't get enough purchase to keep the fence in position. Hand screws work well so long as you get the jaws parallel and firmly set; otherwise the router's vibrations can shake them loose. Small bar clamps arc used a lot in our shop. Though I'm not aware of such problems firsthand, 1 have read that some woodworkers have trouble with them shaking loose. C-clamps are probably the most sure, but also the most vexing to lighten

A test cut will tell you all about the fence setting; the proof is in the cut, so to speak. To adjust the fence a small amount, scribe a pencil line along the fence—where the fence will be moving away from it—and measure with your rule from that line to the fence. Just remember that the distance you move one end of the fence will be halved at the bit.

To set the fence with a combination square, you first need to slide the head to the end of the rule. Set the head against the fence with the rule crossing above the bit, as shown here. You can establish the fence position from the near or far cutting edge or the (presumed) bit axis.

The shop-made depth gauge used to set the bit height can be a big help in setting the fence, too. Determine the distance from fence to the edge of the cut farthest from it. Set the gauge to that measurement. Butt the gauge slide against the hit's cutting edge, as shown, and bring the fence up against the base.

and uniightcn. I personally like Vise-Grip C-clamps. which can be set and released with one hand.

Positioning the fence is a key step in setting up. The main con-ecpt to remember here is that you only have to establish the distance between the bit and the fence. With a router table, unlike a tabic saw. you don't have to worry about whether your fence is or isn't parallel with the cutter.

The usual fencc-sctting procedure is to place the fence on the tabletop. quickly get a rough setting, and clamp one end. Then you refine the setting by shifting the free end by the necessary fractions of an inch as you measure the gap between bit and fencc. Then you clamp the second end of the fence.

Ideally, you measure between fcncc and bit with a square of some sat, and you measure from the fence to cither the cutting edges or the axis of the bit. While the fence doesn't have to be square to an edge or parallel to an edge, the line you measure between bit and fencc must be perpendicular to the fence. If you set the head of a square against the fence's face, the blade will jut away from it at a right angle. Slide the blade up to the bit and measure.

Again, to get a really accurate setting, you need to measure from theaxisofthebitorfrom the cutting edges. Rotate the bit a little with your hand to align the cutting edges, and get the rule as close as possible to the appropriate edge. Pinpointing the axis? Good luck! It's tough to estimate accuratcly where the cxact ccntcr of the bit is.

One important bit of savvy is that when you move only one end of the fcncc. the amount the cut moves is one-half the distance you move

the fcncc. I'm not talking here about a change where you move the fencc while you're monitoring the change at the bit with a rule. I'm talking about measuring a sample cut and determining that you want to adjust the cut V* inch. To get that Winch adjustment, you can pencil a line

along the fence at one end, then move the fence '/■» inch away from the line. Obviously, you don't want to put the line where the movement will cover it. (And on a laminate-covered tabletop, you can erase the line completely when the job s done.)
