INSTRUCTIONS Making the templates Clamp a bccker board by its back two corners to your dr'll press table and install a fly cutter. Extend the cutter arm fully and 3E SURE it clears the clamps (see Fig. 1)1 Set your drill press to its slowest speed ar.d install the fly cutter. Drill into the eacker board and set the depth stop so the tip of the cutter will go only halfway through the thickness o" tne stock from which you will cut the templates. By cutting halfway into the stock, flipping it over and drilling the rest of the way from the other s;de, "ear out is eliminated on the edges of "he templates. The backer bocrd assures that you won't accidentally hit the steel drill press table. It also helps eliminate tear out in the pilot hole when the templates are cut. Fig. 1. Clamp backer board to drill press and check clearance. Slide the cut"er arm all tne way in so the coumer balarce is up against the shank. Be sure the cutter tip is set so that its fla* side is towards the pilot drill bit. This ensures tha" the edges of the templates will be flat, not beveled. Cut the first template (see Fig. 2). The second template is cut by moving the cutter arm out 1/16". This is easily done using shims made from the plywood tha" the templates are cut from. Cut them roughly 1/4" square (see Fig. 3). A shim is placed between the counterweight and the pilot shank, cs shown in Fig. 4. Push the shim out after the cutter arm is set, then cut the second "emplate. Adding one more shim after each templaie is cut will increase the diameter of each template by 1/8". As I cut each template, I numbered it and put it on a 3/16' dowel. A piece of folded tape :<eeps them from sliding off (see Fig. 5). There is no way you can hold ell those 'tile shims as you set the cutter arm. A drop of CA Fig. 2. Cutting the first template. Fig. 3. Ply wood shims will be used to make progressively larger circles. Fig. 4. The first spacing shim is in place. Fig. 5. Adding shims and stacking up the circle templates. (cyanoacrycte) glue between them does the job. Repeat "his process until you've cut all the templates you want. Fig. 6. The rack's first layout lines.

Making the template storage rack The storage rack can be made by using a squcre and some of the templates to lay out lines directly on the wood. This one was made using 1/2" plywood. That's what I had lying around. You can make yours "*rom plywood or so id wood—whatever you have available. I woulcn't go less than 1/2" for the top, though. The first layout lines are the width of the blade of my squcre from the left side and bottom of the wood. With the largest template set against those lines, the right side blade with margin is drawn (see Fig. 6). Next, a centerline |
