HALF-BLIND DOVETAILS WITH CLAMPING BOARDS

You can mount your half-blind template that comes with the 4210 and 4212 jigs and the 4211 accessory kit to a board. This method, however, limits your workpiece width capacity to 8".

SETUP

Items needed to setup for the half-blind dovetails:

1.Wood to make the clamping board parts

2.Clamps

3.2" #10 wood screws (2)

4.1/4-20 threaded T-nut

5.1/4-20 x 4" bolt

6.1/4" washer

NOTE: These instructions can be modified for making half- blind dovetails with the through dovetail template and for the miniature dovetail template (See the section “HALF-

BLIND DOVETAILS WITH TAIL BOARDS THICKER THAN 7/8").

Fig. 14A

Step 1 -

Step 2 -

Make a main clamping board 1-1/2" x 3-1/4" x 16". Square all of the sides. Make a mortise through the board and drill pilot holes for #10 wood screws (Fig. 15A).

NOTE: Threaded inserts and #10 flathead machine screws can be used in place of the #10 wood screws.

Make the offset clamping block. Make a counterbore for the threaded T-nut (Fig. 15B).

NOTE: If your pin board is thinner than 3/4", modify the dimension. You may need to use extra washers to prevent the bolt from sticking out.
