Abstract: Portable exercise incline board devices and methods for exercise and balance fitness that can be easily assembled, disassembled and transported. The incline board can be assembled from a generally rectangular top ice with raised upper surface, along with a pair of right triangle support pieces and a rear vertical piece wherein raised protrusions align into mateable grooves so that the pieces slide and lock together for assembly and slide apart for disassembly.

Abstract: A shaft straightening press including a movable carriage which moves along the length of an "I" beam frame and includes a hydraulic ram used for straightening a shaft placed upon the "I" press bed. The carriage rides upon the lower flange of the "I" beam by means of four wheels fixed to the carriage and making rolling contact with the upper surface of the lower flange. The carriage is locked into place by a pair of hydraulic jacks which lift the carriage, thereby disengaging each of the wheels from rolling contact with the lower flange. The carriage has a cross-sectional shape of a rectangular frame so that when the hydraulic jacks are lifted, the lower end of the rectangular frame of the carriage contacts the lower surface of the lower flange of the "I" beam, thereby securely locking the frame-shaped carriage in place. Slideable precision roller blocks and V-blocks are provided on the upper flange of the "I" beam for positioning and orienting the shaft to be straightened.
