15 Some items to consider when purchasing alternate bits for half-blind dovetails are: 1. A shallow angle of the bit requir es a deeper cut. A steeper angle requir es a shallower cut. 2. The diameter of the bit should be slightly greater than 1/2". The gr eater the diameter , the deeper the cut. 3. The bit should have a cutting length at least[...]

16 DOVET AIL DADO BITS Any dovetail bit can be used to make dovetail dados (sliding dovetails) as long as the bit does not cut into the template guide or the base of the jig. The process is identical to that of the standar d dovetail dado. Also, you can use template guides smaller than 3/4" OD which will have the effect of making the dado slot[...]

Set the table saw blade so that the height of cut of the saw blade is the same as the thickness of the mitered half-pin. Use a table saw with the miter gauge [...]

20 HALF-BLIND DOVET AIL, SKIPPED PIN METHOD This method is similar to making standard half-blind dovetails, except that the tails and pins are cut separately . Cut the tails first. Use a scrap workpiece (thick enough to prevent contact with the base of the jig) to support the template. Fig. 33A Hold the pin board against the tail boar d and mark th[...]

21 Make a climb cut from right to left. Cut only between the fingers where you want the pins to be (Fig. 34A). Use the router to r ound over the ends of the cuts (Fig. 34B). The joint will hide any accidental excess material cut (A) Fig. 34C. Use a pencil to mark the location of the ends of the templet fingers on the wood (Fig. 34D). Remove the tem[...]

22 SA W KERF ALLOWANCE METHOD An effective way to match the grain in a decorative box is to make the box fr om one piece of wood and then cut the lid with a table saw . However , if the dovetails are evenly spaced, they may be unattractive because the saw kerf removed needed material. NOTE: For this method, you will need a spacer block equal to the[...]

23 Center and clamp the tailboard as normal, but use the spacer on the left side of the boar d (A) Fig. 38A. (The spacer will cause the board to move slightly of f center to the right). Mark between the two fingers on the template where you want the kerf to be (B) Fig. 38B. Cut the tails from the far left to the right. Stop at the mark (Fig. 38C). [...]

24 END-TO-END JOINTS Y ou can use the 4200 series dovetail jigs to join boards end-to-end to incr ease length and to make visually interesting lar ger panels.
