ABSTRACT:
A guard for a grinder wheel wherein the guard has a base structure upon which the grinder is mounted to affix it to a support and the base has four upright members and cross-structures which support bullet proof clear plastic through which the grinding operations can be observed by the operator. A lighting fixture is mounted through the transparent plastic such that the transparent plastic cannot be removed from the guard without completely disassembling the lighting fixture which prevents the operator from removing the guard from the machine. The lighting switch for the lighting fixture is interconnected with the switch for driving the grinder motor so that the operator will know when the light is turned off that the grinder motor has been turned off.
