HALF-BLIND DOVETAILS WITH CLAMPING BOARDS

board. This method, however, limits your workpiece width capacity to 8".

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.
