FIGURE 66 PROJECT RIGHT SIDE OR PROJECT LEFT SIDE TOP BACK-UP BOARD 42 TOP OF THE BASE FRONT BACK-UP BOARD “OUTSIDE SURFACE” SHOULD BE VISIBLE ON THIS SURFACE BEFORE POSITIONING THE FRONT BACK-UP BOARD CAUTION NEVER LIFT THE ROUTER UPWARDS WHEN THE ROUTER IS ON AND THE ROUTER BIT ROTATING OR WHEN THE GUIDE BUSH- ING IS NEAR TO OR TOUCHING THE TEMPLATE. THIS CAN CAUSE DAMAGE TO THE DOVETAIL JIG; OR LOSS OF CONTROL OF THE ROUTER WHICH CAN RESULT IN SERIOUS BODILY INJURY. 19. After the cut has been made, the workpieces should look like those illustrated in Figure 67. 20. Remove the workpiece and back-up boards from the Dovetail Jig. 21. The back-up boards can be reused if the cut portions of boards are cut off. AFTER BEING REUSED UNTIL THEY NO LONGER SERVE THEIR INTENDED FUNC- TION, NEW BACK-UP BOARDS MUST BE MADE. 22. TO CUT CORNER #3 OF THE PROJECT LEFT SIDE, position the top back-up board on top of the base so that it lines with the front of the base and abuts the right top stop block as shown in Figure 63. 23. Continue as Steps 6 through 23. 24. TO CUT CORNER #2 OF THE PROJECT RIGHT SIDE, position the top back-up board on top of the base so that it lines up with the front of the base and abuts the left top stop block as shown above in Figure 66. 25. Lightly clamp the back-up board in place. 26. Position the project side against the front of the base so that the top surface abuts the left front stop block. The use of a front back-up board at this step is also recommended. It is positioned between the project side and the clamping bar as shown in Figure 67. The front back-up board is described in Step 6 on page 40. 27. Continue as in Steps 8 through 19 above. 28. After the cuts have been made, the workpieces should look like those illustrated in Figure 61. 29. Remove the workpiece and the back-up boards from the Dovetail Jig. NOTE: THE BACK–UP BOARDS ARE REUSABLE. FIGURE 67 TOP BACK-UP BOARD DOVETAIL CUTS AUXILIARY TEMPLATE SUP- PORT (AS NEEDED) FRONT OF THE BASE 30. TO CUT CORNER #4 OF THE PROJECT LEFT SIDE, position the top back-up board on top of the base so that it lines up with the front of the base and abuts the left top stop block as shown is Figure 66. 31. Continue as Steps 27 through 32 above. 32. At this stage the project sides should look like those illustrated in Figure 61. FRONT BACK-UP BOARD
THE FOLLOWING DESCRIBES THE PROCEDURE TO BE FOLLOWED FOR CUTTING THE PROJECT FRONT AND BACK NOTE: Any joint fit adjustments that may be required can only be made when cutting the project front and back pieces. That is, adjustments are made to project front and back pieces ONLY, not to the side pieces. 1. Assemble the .40" guide bushing to the router baseplate, as described in a previous section. This is the smaller of the two guide bushings furnished with this product. 2. Install Vermont American #22437 or Magna #M91016 straight router bit, to the router as described in your Router Owners Manual. Shank engagement should be a minimum of 3/4". VERMONT AMERICAN #22437 OR MAGNA #M91016 STRAIGHT ROUTER BIT CAUTION MAKE SURE THAT THE ROUTER BIT IS ALIGNED WITH OR CENTERED IN THE HOLE IN THE GUIDE BUSHING. TO DO THIS, LOOSEN SCREWS HOLDING BASE PLATE OR ADAPTER PLATE TO ROUTER, CENTER GUIDE BUSHING HOLE WITH RESPECT TO ROUTER BIT AND RETIGHTEN SCREWS SECURELY. CAUTION WHEN SETTING THE DEPTH OF CUT, MAKE ABSOLUTELY SURE THAT THE COLLET NUT DOES NOT CONTACT (TOUCH) THE GUIDE BUSH- ING. THIS CAN CAUSE THE GUIDE BUSHING TO HEAT UP EXCESSIVELY DURING CUTTING WHICH CAN FIGURE 68 PROJECT FRONT OR PROJECT BACK .40" DIA. GUIDE BUSHING TOP BACK-UP BOARD 43 CAUSE DAMAGE TO THE TEMPLATE. TO CORRECT THIS SITUATION OR PREVENT IT FROM OCCURRING, REPOSITION THE ROUTER BIT IN THE ROUTER 3. Adjust the depth of cut. The depth of cut for an OPEN DOVETAIL JOINT is equal to the thickness of the mating part. That is: FOR CORNER #1 OF THE PROJECT FRONT, THE DEPTH OF CUT IS EQUAL TO THE THICKNESS OF THE PROJECT RIGHT SIDE. FOR CORNER #4 OF THE PROJECT FRONT, THE DEPTH OF CUT IS EQUAL TO THE THICKNESS OF THE PROJECT LEFT SIDE. FOR CORNER #2 OF THE PROJECT BACK, THE DEPTH OF CUT IS EQUAL TO THE THICKNESS OF THE PROJECT RIGHT SIDE. FOR CORNER #3 OF THE PROJECT BACK, THE DEPTH OF CUT IS EQUAL TO THE THICKNESS OF THE PROJECT LEFT SIDE. Use the depth gauge on the base of the Dovetail Jig, as described in a previous section, as a starting point 4. At this point it will be necessary for you to make a top back-up board. The reasons for the top back-up board are to minimize splintering, provide support for the template and prevent damage to the Dovetail Jig. The top back-up board is a scrap piece of wood having the following dimensions: LENGTH: 6" to 8", sufficient length so that it can be clamped by the top clamping bar and be used more than once; WIDTH: 2" wider than the width of the project front (or back) THICKNESS: 1/8" to 1/4" thicker than the thickness of the project front (or back); THIS IS TO PREVENT ACCIDENTALLY CUTTING INTO THE DOVETAIL JIG. This can also be accomplished by using more than one piece of scrap as long as the resultant length, width, and thickness are as described. 5. TO CUT CORNER #1 OF THE PROJECT FRONT, position the top back-up board on top of the base so that it lines up with the front of the base and abuts the left top stop block as shown in Figure 68. TOP OF THE BASE FRONT BACK-UP BOARD FRONT OF THE BASE “OUTSIDE SURFACE” SHOULD BE VISIBLE ON THIS SUR- FACE BEFORE POSITIONING THE FRONT BACK-UP BOARD AUXILIARY TEMPLATE SUPPORT (AS NEEDED)
