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").

Step 1 -

Make a main clamping board 1-1/2" x 3-1/4" x 16".

 

 

DRILL A 5/16 " HOLE

 

 

Square all of the sides. Make a mortise through the

board and drill pilot holes for #10 wood screws (Fig.

NOTE: Threaded inserts and #10 flathead machine

MAKE A COUNTERBORE

 

 

screws can be used in place of the #10 wood

screws.

 

 

 

 

 

 

T-NUT

 

 

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

 

 

1-5/8"

 

 

the dimension. You may need to use extra washers

 

 

 

 

 

 

 

 

 

to prevent the bolt from sticking out.
