Making the Baseplate

In this situation very accurate work is essential. Because it is tough to get the baseplate trimmed dead-on with your first attempt, I've included tips on fine-tuning the baseplate.

1. Cut and mount the blank. Cut a square of acrylic or polycarbonate, making it about an inch or so larger than the factory baseplate. Leave the protective paper bonded to the plastic for now. Drill mounting holes, using the factor)' baseplate as a template. For the baseplate to be self-centering on the router base, you have to mount it using flat head screws. (See the chapter "Center-Finding Baseplate" on page 85.) This baseplate especially needs to be self-centering, so countersink the mounting holes.

Mount the baseplate blank on the router.

2. Mark the centerpoint. Mount the baseplate blank on the router. Chuck a V-grooving bit in the router. Lower ihe bit til it touches the blank. Turn the bit a few times by hand, marking the centerpoint. For the sake of accuracy, keep the mark as small as possible.

Acrylic, polycarbonate, and phenolic are all suitable.

FRACTIONATING BASEPLATE LAYOUT

For a Milwaukee router (with a 6'/i6"-dia. baseplate)

Mark the baseplate blank's centerpoint by lowering a V-grooving bit to the blank, then turning it by hand. You neither need nor want a large mark, so don't overdo it.

The proof of your baseplate's accuracy lies in actual cuts. Here, I'm measuring a test cut made using each edge of the baseplate, and I'm jotting down the measurements so I can assess the needed fine-tuning. The zero edge cut will equal the bit diameter, no matter what. It is xfr inch here. Both the +]Ao and +'/& edges are %a inch under. If the edge is also inch under, only the zero edge will have to be jointed.

3. Trim the baseplate. Remove the blank from the router. Measure from the centerpoint to the first side and mark it for trimming. (Have this be the zero side.) I found it helpful, in laying out the cuts, to pencil perpendiculars (not diagonals) through the centerpoint. In addition, 1 found that measuring one side and immediately cutting that side minimized confusion. As you trim a side, mark which side it is (zero,-t-'/io, and so forth). I made these cuts on the table saw.

When the trim cuts arc done, peel the protective paper from the baseplate. As you do so, transfer the Libels from the paper to the plastic itself. A permanent marker, such as Sanford's Sharpie, will do the job.

4. Bore the bit opening. With the baseplate trimmed, bore the bit opening. You can do this with a large-diameter bit on the drill press or by remounting the baseplate and plunge-boring with a large-diameter straight bit.

5« Test the baseplate. The proof of your work is in the dadoing. Do the following. Clamp a T-square to a 6- to 8-ineh-wide scrap. (Sec "T-Square" on page 69 for plans.) With the zero side riding this fence, rout a dado across the board. Turn the router to reference the fence with the "-f'/ii." side, and rout about three-quarters of the way across the board, widening the dado. Repeat with the "•f'/fe" side, going about hallway. Finally, rout about a quarter of the way with the "+^6" side.

Set the router aside, and very carefully measure the widths of the four different sections. Dial calipers will give you a very accurate measurement. If you hit the increments on the nose, pat yourself on the back. But if you missed them, do a little fine-tuning.

3. Remove the blank from the router, and trim it. Lay out and cut the "0" edge first. Measure from the centerpoint, trimming %" from the edge. Label that edge "0".
