R 408.12759 Lathes.

Rule 2759. (1) A profile or swing-head lathe shall have all cutting heads covered by a metal guard. If the guard is constructed of sheet metal, the material used shall be not less than 14 gauge in thickness or equivalent. If cast iron is used, it shall be not less than 3/16 inch in thickness. It is not required that the hoods retain a thrown or broken knife. (2) Cutting heads on wood-turning lathes, whether rotating or not, shall be covered as completely as possible by hoods or shields, which should be hinged to the machines so they can be moved back for making adjustments. (3) Shoe-last and spoke lathes, doweling machines, wood-heel turning machines, and other automatic wood-turning lathes of the rotating knife type shall be equipped with hoods enclosing the cutter blades completely, except at the contact points, while the stock is being cut. (4) A revolving tool lathe used for turning stock held between the 2 centers shall be equipped with guards extending over the tops of the tool in order to prevent the work pieces from being thrown out of the machines if they become loose. (5) A revolving tool lathe shall be equipped with a suction hood properly connected to an exhaust system. The hood shall be formed over the revolving tools to serve as a guard. They shall be constructed of metal of a thickness not less than that specified in subrule (1) of this rule. SANDING MACHINES
