Abstract: A method and apparatus for orienting and rigidly clamping a cutting tool in alignment with a lathe's spindle axis in a manner to minimize the setup time required. The method and apparatus uses the lathe's spindle chuck for establishing and clamping the angular orientation and radial position of a cutting tool retainer in order to align the cutting tool with the lathe's spindle axis.

Abstract: A skate roller assembly, incorporating an endless belt, configured to support a user's weight and present a substantially continuous arcuate bearing surface to a supporting ground surface. The roller assembly is intended for attachment to a boot foot plate and is characterized by an elongate endless belt comprised of a plurality of elements hinged relative to one another to enable the elements to move around a closed loop including a longitudinally oriented lower loop portion. The belt, in the region coincident with said lower loop portion, forms a rocker for supporting a user's weight and presenting a substantially continuous arcuate bearing surface to a supporting ground surface. The rocker is formed by a group of successive belt elements, or are segments, which, when in the lower loop portion, engage to form an arc defining said arcuate bearing surface. A user's weight is loaded onto the rocker via one or more lead transfer members, e.g., idler wheels which engage the belt inner arcuate surface.
