Shiplap Moulding 8-5/8" - 8

This beveled channel shiplap siding molding 8-5/8" - 8 measures 8.625" wide by .750" thickness, permitting the detail to be machined out of four quarter lumber. The ordinary profile is composed of a 6-3/8" wide flat line on the top center, attached to a 1/4" wide by 3/8" deep chamfer joined to a 1-1/4" wide line segment and a 3/4" tapered edge on the left, the opposite side retains a 3/4" tapered rabbet and a 1/4" wide by 3/4" deep beveled edge to receive the other side. When two pieces of milled lumber are joined together they create a 1-3/4" wide beveled channel between the merged boards.

Our professionally designed acrylic templates and knives include the required draft angles to maintain the ability to sharpen the blades properly without modifying the detail, while simultaneously prolonging the milling time between sharpening. This cad generated dxf file (purchase in the link below) contains three skillfully drafted template designs for producing knives for this shiplap siding pattern, one for the entire width of the design, one for milling just the profile portion (for rustic lumber) and one for the left side cutter head. All our innovative profiles have a proven unbroken computer numerical control (CNC) tool path expediting the production process.
