ABSTRACT:
A log holder for supporting a log in a horizontal orientation by engaging one end of the log, thereby leaving the other end free for cutting. The holder includes a base (12), a frame (20) extending upwardly from the base, upper (24) and lower (22) supports mounted to the frame above the base, and a counterweight support (26). The lower support includes an upwardly facing first contact surface (56). The upper support includes a downwardly facing second contact surface (70, 72, 74) that is horizontally spaced from the first contact surface in a first direction. The lower and upper contact surfaces are vertically positioned with respect to one another such that one end of the log (10) can be supported therebetween in a generally horizontal orientation, with the log extending from the lower support in a direction opposite the first direction. The counterweight support is mounted to the frame above the base and is horizontally spaced from the upper support in the first direction. The upper support may include a plurality of downwardly facing second contact surfaces of different sizes. The holder may further comprise an auxiliary lower support (28) adjustably and horizontally spaced from the first mentioned lower support for supporting short logs, and a projection extending from adjacent the upper support towards the lower support for spearing one end of a log.
