Tongue & Groove 3/8" - 12

This 3/8" - 12 butt joint tongue & groove measures .375" thickness, enabling machining out of resawn five-quarter lumber; the width gets milled to any desired size within the parameters of the machinery used to cut the pattern. The simplistic functional profile composes a 1/8" wide by 9/64" deep centered tongue and a groove; there is a .010" void in the joint area for expansion and contraction of the wood during seasonal changes in relative humidity. We offer an alternative profile in the same thickness with a different sized joint for your review and consideration, tongue & groove .375" - 6. Our professionally designed acrylic templates and knives include the required draft angles and blend areas to maintain the ability to sharpen the blades properly without modifying the detail, while simultaneously prolonging the milling time between sharpening.
