This Shiplap Siding Moulding 3/4" - 23 measures .750" thickness. The width can be milled to any desired size within the limitations of the equipment used to machine the pattern. The detail has a .500" depth of cut on the right vertical set of knives and a .969" depth of cut on the left vertical cutters.

The profile is comprised of a 1/2" wide by 3/8" tall rabbet on the right backside, with a 1/2" wide by 3/8" tall rabbet and a 3/8" wide bevel on the left face side of the detail. When two pieces of milled lumber are joined together they create a 3/8" wide by 3/8" deep one half vee groove on the face side of the joined boards.
