PREPARING ROUTER

1. DISCONNECT THE ROUTER FROM THE POWER SOURCE.
2. Insert templet guide, (A) Fig. 4, in the hole (B), in router sub-base (C).
3. Install templet guide locknut (D) on templet guide and firmly tighten to lock templet guide in sub-base.
4. Insert dovetail bit, (A) Fig. 5, through templet guide into router collet.
5. Adjust the router so the dovetail bit projection (B) from the bottom of the router sub-base (C), is 9/16″.

CLAMPING DRAWER PARTS

1. Temporarily clamp the left side of the drawer “inside out” under the front clamp bar and extend approximately 1/4″ above the top surface of the base as shown in Fig. 6.
2. Place the drawer front “inside up” underthe the top clamp bar and against the side of the drawer which extends above the surface of the Dovetail Fixture/Jig.
3. Place the 1/2″ half-blind dovetail templet on top of the drawer front. Using a standard scale or ruler, adjust locknuts, item 7, Fig. 1, so there are 19/32″ from the back ofthe templet slots to the edge ofthe drawer front at both ends ofthe templet (see Fig.  8). Tighten knurled nuts, item 6, Fig. 1, to secure the temple in place.
4. Loosen the top clamp bar and position the drawer front so that the left edge is 3/16″ (see Fig. 8) past the left edge of the first temple slot and clamp in place.
5. Remove 1 /2″ half-blind dovetail templet (DO NOT LOOSEN TOP CLAMP BAR) and locate #1 edge guide against drawer front, secure in place,e and replace 1 /2″ half-blind dovetail templet and secure it in place.

ROUTING DOVETAILS DISCONNECT THE ROUTER FROM THE POWER SOURCE.

1. Be sure the router motor is “off” and plug into a power source.
2. Set router squarely on finger templet to the right of drawer pieces.
3. Make sure the bit is clear of work and will not strike the Dovetail Fixture/Jig base.
4. Start the motor and make the first cut along the entire outside edge of the finger templet, from right to left, in the direction of the arrow (A) Fig. 9. This will prevent chipping of the edge of the drawer piece when the router is moved in and out of templet.
5. Now, carefully move the router from left to right around the templet outline, in and out of the slots as shown by arrow (B) Fig. 9.
6. Next, examine the drawer pieces to make sure they have been cleanly routed. See Fig. 10.
7. Remove drawer pieces and fit them together, matching dovetail (A) with slot (B), Fig. 10. The joint is loose, slightly increasing the depth ofthe cut. The joint is tight, slightly decreasing the depth othe f cut. The bit is raised or lowered by adjusting the router motor in the router base with the motor “off”.
8. After obtaining a snug dovetail, assemble parts and check the relation of the end of the drawer front to the side of the left side of the drawer. If the drawer front overhangs the s side othe f drawer, decrease e 19/32″ dimension iStepep 3 under CLAMPING DRAWER PARTS. Ithe the f side othe the f drawer overhangs the the s front, increasing the e 19/32″ dimension.
9. Fig. 11 shows both the left and righcornerser of a drawer fitted together after they were both routed from the left end of the templet. Note the location of partial pins on drawer sides.
10. If for appearance reasons the partial pins are desired to be in the same location on both sides of the drawer as shown in Fig. 12, the output on the right end of the drawer front and the right side of the drawer on the right end of the templet. Adjust the edge guide the same as those on the left (mirror image).
