Tongue & Groove 5/8" - 5

This 5/8" - 5 v-groove paneling measures .625" in thickness, and the left vertical cutter head determines widths at the milling time. The single-sided profile consists of a 13/64" tall by 1/4" deep tongue & groove with a 1/8" wide by 1/8" tall chamfer on the edge of the pattern. There is also a .006" void in the joint area for expansion and contraction of the wood to accommodate seasonal changes in relative humidity. When two pieces of milled lumber are merged, they will create a 1/4" wide by 1/8" deep vee groove on the face side of the joined boards.
