Tongue & Groove 3-1/4" - 11

Tongue & Groove 3-1/4" - 11

Tongue & Groove 3-1/4" - 11

This beautiful tongue & groove beadboard siding 3-1/4" - 11 measures 3.500" wide by .750" thickness, enabling the pattern to be milled from four quarter lumber. The attractive profile is composed of a 1/4" tall by 9/32" deep tongue & groove with a .010" void in the joint area for expansion and contraction during seasonal changes in relative humidity. The face of the detail retains a 2-5/8" wide flat area in the center, joined to a 1/8" wide by 9/32" deep sunk fillet attached to a 3/8" wide half round bead with another 1/8" flat line on the opposite side. When two pieces of milled lumber are joined together they create a 3-1/4" face coverage dimension with a 5/8" wide channel with a recessed half round circle in the center. We offer a couple of other similar profiles with different inner dimensions for your review and consideration, tongue & groove 3.250" - 12 and tongue & groove 5.250" - 2.

This cad generated dxf file (available for purchase in the link below) contains three skillfully drafted template designs for producing knives for this creative beadboard pattern. All our innovative profiles have a proven unbroken computer numerical control (CNC) tool path expediting the production process.
