A fixture for facilitating the serial engraving of a plurality of cylindrical objects such as glasses or mugs mounted on individual serially arranged stations along a master base plate. Each station includes a drive structure and, spaced therefrom, a passive support structure. The two structures in each station can be gang-adjusted for object length. In addition, the support structures can be height-adjusted to level the engraved surfaces of tapered objects. All of the drive structures include drive wheel pairs and all are driven by a single stepper motor via a single shaft and individual belt and pulley systems.

Devices, kits, and methods for making a carved crayon are provided. In one aspect, a crayon carving device includes a base, a pantograph armature coupled to the base, a crayon positioner, and at least one guide template parallel to the crayon positioner. The pantograph armature includes a motorized drive shaft with a drill tip for carving an outside surface of a crayon body, as well as a guide tip for tracing along a guide template that directs where the drill tip carves. In some embodiments, the guide template includes a stationary bridge support and a plurality of removable carving bucks that insert into one of multiple openings on the bridge support. The surface features of each of the carving bucks may be traced by the guide tip to generate a corresponding carving on the surface of a crayon body.

A ring holder system comprising a ring holder base with a body that can be oriented horizontally and vertically on a flat work surface. The base includes a single mandrel extending from a front end face of the base, angled upper tool mounting surfaces circumferentially offset from a top surface of the base, and a flat rear end face for resting the base in a vertical work orientation on a flat surface. A horizontal tool adapter mount is configured to be removably mounted on one of the angled upper tool mounting surfaces, and a vertical tool adapter is configured to be mounted on the bottom surface of the base in the vertical work orientation. The mandrel includes a threaded mounting ring at an inner end of the mandrel adjacent the front end face of the base for mounting accessories such as vises and pitch cups rotatably on the mandrel in the vertical work orientation.
