4. Cut out the center of disc C with a 2-1/2-inch hole saw or scroll saw. While you’re at it, also cut out the center of the body piece (E) and set piece E aside.
Now, take the center (scrap) stock you just cut out of disc C and clamp it down over the jig pivot bolt. Drill a 1/4-inch diameter x 3/4-inch deep hole at the centerline for the slide lever, next to the 5/8-inch vertical hole as shown in Figure 2.
5. Chamfer the 5/8-inch diameter holes on discs C & D. Use your Drill Press with a 1-inch countersink bit. Also locate and create a countersink “dimple” on piece A to catch the gum ball as it exits the hole in the side of disc B.
6. Drill a 5/8-inch diameter hole for the gum return on disc B. Use your MARK V in Horizontal Boring mode, with the jig clamped to the table surface as shown in Figure 3. Tilt the table 5-degrees so your bit exits through the surface of the disc as it approaches the center. Continue . . . |
