Jig simplifies difficult pocket-hole joints
Commercial pocket-hole face clamps work well for parts of the same thickness aligned flush, such as a typical box corner or face frame. But clamping two parts of varying thickness, or ones in the field of another, as shown above, proves trickier. Here's my solution.
Clamp the parts together in this two-part jig. The workpiece with pocket holes goes between the adjustable jaws, with the other workpiece clamped between the jig's rails. Be sure to precisely align the jaws for a square clamp-up. When installing the carriage bolts in the rails, drill a shallow recess for the bolt head.
