Rotoplane rotary planers from Ogden Group use a single rotary disk with knife inserts mounted around its circumference. The rotary cutting motion produces a consistent, accurate cut and a porous surface that aids in gluing, according to the company.
Two models of jointers are available from Invicta USA, both with cast-iron frame and table, rear cutterhead guard, knife gauge, bridge-type guard, a tilting fence with positive stops of 90 and 45 degrees and one set of knives. Model DI-42 is a larger-capacity machine than model DI-32.
