Description:

The two inventors earlier patented (3,162,220) a stop system for cutting dimensional lumber to length, which was manufactured by Speed Cut, Inc.

"A disc body portion is grooved diametrically in one end face to receive differently profiled spindle turning bits and the body portion has a central axial threaded bore to accept a bolt serving as a temporary handle to hold the cutting bits in contact with a grinding wheel to sharpen them. The unitized disc body portion and bits are held clampingly during use between two body members of a bar-like rockable wood lathe cutting tool with the threaded securing rod of such tool passing through the threaded bore of the disc body portion."
