If no provision is made to relieve the hydraulic pressure of air and glue, hammering the dowel home or clamping the joint can split the wood. When dowels are glued into blind holes, a very common case in dowel-based joinery, there must be a path for air and excess glue to escape when the dowel is pressed into place. Since the 19th century, some of these dowel machines have had power feed mechanisms to move the stock past the cutting mechanism. Typically, the mechanism is open-ended, with material guides at the machine's entry and exit to enable fabrication of continuous dowel rods of unlimited length. Such machines may employ interchangeable cutting heads of varying diameters, thus enabling the machines to be quickly changed to manufacture different dowel diameters. įor modest manufacturing volumes, wood dowels are typically manufactured on industrial dowel machines based on the same principles as the rotary cutters described above. Frequently, these are small bench-mounted tools. Machines based on this principle emerged in the 19th century. Ī second approach to cutting dowels is to rotate a piece of oversized stock past a fixed knife, or alternatively, to rotate the knife around the stock. The sharp edges of the hole shear off the excess wood. To make a dowel, a piece of wood is split or whittled to a size slightly bigger than desired and then driven through the hole in the dowel plate. (or better, hardened tool steel) plate with a hole having the size of the desired dowel. The traditional tool for making dowels is a dowel plate, an iron
