2. Lay out the baseplate on the blank. Follow the appropriate Offset Baseplate Ixxyout drawing. "Appropriate-' means: Use version 1.0 for the smaller baseplate, version 2.0 for the larger.

With a compass, scribe a 7-inch-diamctcr circle at one end of the blank, a -i-inch-diameter circle at the other end. Use a straightedge to guide to scribing of tangents connecting the two circles. Be sure you clearly mark the centerpoints of the circles.

3. Cut out the template. Use a saber saw or band saw to cut out the baseplate shape.

For the best appearance of the finished baseplate, the template edges must be smooth and fair. I've found that a smooth file is useful in fairing the edges. A portable belt sandcr is a bit aggressive and difficult to control for something like this. I think, but give it a try if you want. After filing the edges, smooth them with a random-orbit or pad sander.

4. Bore the holes. To lay out the mounting-screw holes, use the router's baseplate. Slick two or three small pieces of carpet tape on the router's factory baseplate, line it up on the template, then press it firmly in place. It would he cool, of course, to have the bit axis match the centerpoint of the larger circle, but that alignment may be j bit hard to achieve. In the real world, that match is immaterial.

What is significant is die orientation of the router's handles. The drawing Handle Orientation shows the two principal alignments. I like the top one. but you suit yourself. Just align the baseplate on the template so the handles «ill be where you want them.

Drill holes for the mounting screws, guided by the baseplate. Countersink these holes. Drill a Vinch-diameter hole at the ccntcrpoint of the small arc. This is lor the knob's mounting bolt.

5. Lay out and bore the bit opening. Fit a V-

pooving bit in the router's collet. Mount the template on the router. Don't even plug the router in. Bring the tip of the bit in contact with the baseplate, and turn the bit a couple of revolutions with your hand to make the center of the hit mark the ccntcrpoint.

Remove the template from the router, and bore a I'Hnch-diameter hole though the template. Be sure the hole is centered on the mark made by the bit.

6. Make the baseplate. Use carpet tape to bond die template to the square of plastic you've selected for the baseplate. (The appendix has information on the suitable plastics that may help you decide which to use.)

Drill the holes first. Do the mounting-screw holes and the knob-mounting bolt hole. Countersink all the holes.

Rout the bit opening, using a straight bit and a template gudc.To make a bit opening tor standard Porter-Cablc-type template guides, rout a 1 ' »inch hole clear through the mounting plate, using a '«-inch straight bit in a Vinch-O.D. template guide.Then switch to a ' .•-inch straight bit in the same template guide, and rabbet the hole. Measure the flange on a guide bushing, and rout the rabbet that depth It's usually about V32 inch, but check.

If you want a bit opening of a different size, work with other bit/bushing combinations. You can make many different sizes of holes, using that I 's-inch hole in the template as a guide.

Finally, using a pattern bit or flush trimming; bit in your router, trim the mounting plate to size. Pry the template and the mounting plate apart; this is when the masking paper comes off the mounting plate Attach the plate to the router.

Using a template allows you to make multiples quickly and easily. Stick the baseplate material to the template, and feed it around a flush-trimming bit on the router table. You can even adapt a template to more than one model of router, and to both opaque and clear materials.

7. Install the offset knob. I selected a mushroom-style plastic knob from the Reid Tool Supply catalog. The design comfortably offsets the grip from the baseplate. Any number of other styles would work, and suitable styles can be found in many woodworking supply catalogs.

The particular knob I chose has * «-inch threaded insert, so the knob is attached with a A t-inch-long flat head stove bolt.
