Porter-Cable 4210 & 4212 instruction manual Cutting the Joint

Step 4 - Make the straight clamping block. If the workpiece is thinner than 3/4", you will need to modify the dimension (Fig. 15D).

Step 5 - Make two thickness blocks the same thickness as the pin board. Drill a hole big enough for the wood screw to go through (Fig. 15E).

Step 6 - Assemble the board-mounted half-blind template (Fig. 15F).

NOTE: You will not need to remove the half- blind depth bracket.

CUTTING THE JOINT

Step 1 -

Step 2 -

Step 3 -

Clamp the tail board (drawer side) to the main clamping board with the outside surface facing the board (Fig. 16A).

Move the offset clamping block to the right until it touches the tail board (Fig. 16B). Tighten the 1/4-20 x 4" bolt that holds the offset clamping block.

Insert the pin board (drawer front) flush against the tail board and the offset clamping block (Fig. 16C).
