45 Degree Lock Miter Joint - 3

45 Degree Lock Miter Joint - 3

This decorative 45-degree-3 lock miter joint measures .750" in thickness, enabling the detail to be machined out of four-quarter lumber; the width gets machined to any desired size within the parameters of the shaper used to cut the pattern. The unique profile is composed of two 9/32" wide by 19/64" tall interlocking tongue & grooves with .007" void in the joint area for glue to escape from during fabrication. The pattern is machined on a shaper with one board lying horizontally. The other piece standing up, or, laying flat on a moulder bed plate during the machining process.

This professionally drafted template ready computer aided drafting (CAD) drawing exchange file (DXF) (purchase in the box below) contains two high precision template designs to create profile cutters for this interlocking detail.
