Horizontal Savvy

With the router's orientation changed from vertical to horizontal, the methods for fine-tuning your cut must change. "Bit height" becomes a confusing term. Does it refer to an adjustment made on the router, as it does when working at a regular router table? Or does it refer to an adjustment made by moving the swing arm?

To me. the adjustment you make on the router itself is for bit extension. It governs how far out from the swing arm the bit extends. Bit height, when we're talking about the horizontal router table, refers to the height of the bit in relation to the plane of the tabletop.

When you begin to rout, you have to deal with feed direction. It's different: You feed from left to right. But let's not get ahead of ourselves. Do the adjustments first.

Bit-extension adjustment: Easy to do. You can stand beside the router and look straight down on the bit Moreover, you don't have to worry about losing the router's bit-height setting when you loosen the clamp securing the motor in its base. You aren't fighting gravity in this adjustment.

Hold a rule next to the bit and move the router.

Bit-height adjustment: The swing arm's fine-adjustment system works great.

To get a coarse setting, loosen the locking knobs and lift the swing arm. When the setting looks right, tighten the knobs (particularly the two in the slot). Then bring the slide up so the nose of the jackscrew touches the swing arm. Be sure the jackscrew is about halfway out. This ensures that you can lower the arm as well as raise it to fine-tune the bit height.

Make a test cut and measure the cut itself. To deepen the cut, raise the arm. To make it less deep, lower the arm. In both situations, loosen the locking knobs—remember, the arm won't move when you do this—and turn the jackscrew clockwise to raise the arm, counterclockwise to lower it.

If you are a stickler, you'll want to remember that the jackscrew has 16 threads per inch. One complete revolution will alter its height Vig inch. But you also need to know that the pivoting action of the swing arm and the location of the bit axis will halve that height change at the bit. Turn the jackscrew a complete revolution. and the bit height will change inch.

That /s fine-tuning.

Feed direction: As I said, it is from left to right, unlike on a regular router table. This is because you're using what would be, on a regular router table, the back of the bit.

It's easy to figure out. Look at the bit as it extends into the tabletop bit opening. Look at the cutting edge. Does it remind you of the cutters on a jointer.

the way they are pitched into the cut? It does me. I look at that router bit and I can just see it's going to spin toward the left—counterclockwise.

And because you always feed against the cutter rotation, I know I'm going to feed the stock from left to right. In practical terms: Feed from the front of the saw table to the back, just as you would when ripping or crosscutting.
