Has anyone else ever seen or used a light duty indexing head from a company in Cleveland, Ohio? I have only ever heard it called a Cleveland Head. It mounts to the table with one bolt thru the center and will rotate 360degrees. The head will also rotate 360 degrees. the spindle has an indexing plate with 60 teeth for 6 gegrees of rotation per tooth. The indexing pin will swing thru a 7 degree arc which allows for infinite adjustment of spindle location. This head is great for all kinds of general grinding on all kinds of cutting tools.
