Make cut counterclockwise

Blank clamped 7 to scrap plywood or bench

Mark the center of the circle with an awl. Then use the point of the nail in the jig to drop in the hole. Give the nail a couple of taps with a hammer to secure it. Cut the circle by moving the router counterclockwise. Make the cut in several passes, lowering the bit about Vs" after each pass.

your holes for the dowels.) Do the same thing for the top, except this time don't drive the nail all the way through.

When cutting all the circles, you should make the cut in three passes, so set the depth of your router bit's cut accordingly. Be sure to clamp each blank to your benchtop. You'll likely want to protect your work surface from the last router bit pass by putting some scrap below the work.

Also, keep in mind that when you later cut the inside circle of the base, the outer ring should be clamped down so it isn't damaged by the router bit at the moment it's cut free of the outer ring.

Cut the top and the outside base circles. As mentioned earlier, before cutting the inside base circle, you'll need to drill the dowel

holes first because you'll need to use the waste material of the inside circle to align the jig.

Drilling Holes

Prepare to drill the holes for the dowels using the jig you made and the hole-drilling pattern at right. To use the pattern provided here, you'll need to enlarge it 200 percent (double the size). It fits nicely on legal-size paper. Then make five copies, trim to the pattern border and match them up so that corresponding, overlapping lines are in place, as shown at right. Tape the five pages together, then carefully tape them to the top side of the base.

Next, study the pattern and sort out the various circles. The very outside circle is the outside diameter of the top. The next
