The cutting diameter is3^ in. The motor is direct-connected by means of a universalflexible coupling. It is fully enclosed, well ventilated, andfitted with ball bearings, being designed to run at 3600r. p. m. A y^-hp. motor for the 4-in. machine and a J/^ for the 6-in. machine are required. The knife set- ting attachment is furnished when desired. It consists ofa right angle way with a slide block, jointing stone andaluminum guard. It serves as a guide for setting the knivesand by sliding the jointing stone back and forth while thecutter head revolves it will sharpen and join the knives so thatall three knives will cut equally and produce much betterwork.
