Tongue & Groove 3/8" - 1

This 3/8" - 1 channel tongue and groove measures .375" thickness, enabling the detail to be milled out of resawn five-quarter lumber. The width gets machined to any desired size within the parameters of the moulder/shaper used to cut the pattern. The profile comprises a 1/8" tall by 1/2" deep overlap tongue and groove flanked by 1/8" tall vertical lines; this offset pattern is perfect for areas of a room that require blind nailing during the installation process. When two milled pieces of lumber merge, they create a 1/8" wide by 1/8" deep channel/quirk on one face side of the joined boards. There is a .007" void in the joint area for expansion and contraction to accommodate seasonal changes in relative humidity. This knife design includes five-degree draft angles to maintain the ability to sharpen the cutters without altering the profile while prolonging the milling time between sharpening. We have an alternative profile with a 1/16" wide channel for your review and consideration, tongue & groove .375"- 3.
