A tool and a grinding member for installing thereon comprising a support structure having inner and outer portions journaled for relative rotational movement, a guide member for mounting on an object having a surface to be ground, the guide member having a cylindrical portion that extends from the object in a position centered on the axis of the surface to be ground, the inner portion of the support structure having a surface for making sliding engagement with the cylindrical guide portion, a work engaging member for mounting on the outer portion of the support structure in position to engage the surface to be ground when the tool is moved axially along the cylindrical portion of the guide member, the work engaging member having a surface portion contoured to the desired shape of the surface to be ground and having surface grooves formed therein at spaced locations extending thereacross, and a layer of relatively hard, wear resistant materials and a binder formed on the contoured surface of the work engaging member.

A right angle indexer includes an internal torque limiter. The indexer includes an input shaft with a cam, and an output shaft. The cam on the input shaft rotates a hub on the output shaft. The hub is rotatable relative to the output shaft. The output shaft has a driven surface, and the hub has a drive surface. The drive surface includes a plurality of detents which are irregularly spaced about the drive surface. A plurality of rollers are spaced irregularly about the driven surface. The driven plate is biased into contact with the drive plate, and the rollers are received in the drive plate detents. As long as the rollers are engaged in the drive plate detents, rotation of the hub by the cam will cause the driven plate, and hence the output shaft, to rotate. However, if a predetermined torque load is exceeded, the driven plate will become disengaged from the drive plate, and continued rotation of the hub will not cause rotation of the driven plate or the output shaft.

A gage support device for mounting on a setting fixture having spaced opposed fixture setting surfaces in position to support by suspending a gage such as a dial bore gage in position with the contact portion of the gage including the work engaging contacts positioned between the fixture setting surfaces. The support device has adjustment features that can be adjusted so that the device can accomodate gages of different sizes and ranges including an adjustment feature for adjusting the height at which the gage is supported on the setting fixtures, an adjustment feature for adjusting the horizontal position at which the gage is supported on the setting fixture, and an adjustment feature for adjusting the angular orientation of the gage as it is supported relative to the setting fixture.
