Apparatus and tools for constructing cakes are described herein. In various embodiments, an apparatus for use in cake construction may include a frame. In various embodiments, the frame may include a first end, a second end, a top, and a bottom. In various embodiments, a vertical post may pass through the top and the bottom. At least one arm may be rotatably connected to the post, such that the at least one arm is rotatable circularly about a longitudinal axis of the post. In various embodiments, the post may be positionable at a center of a circle coincident with a circular cake such that the at least one arm is rotatable about the post to demarcate a circumference of the circle.

The present disclosure relates to a system and method for adjusting a tool with a plurality of segments for inserting into a cavity of a machine. The method includes determining an initial alignment measurement of at least a portion of the tool; comparing the initial alignment measurement to a target alignment measurement to determine an adjustment amount; and adjusting at least one of the plurality of segments based on the adjustment amount. The tool includes a plurality of segments moveably coupled, where one or more of the plurality of segments comprises a unique dimensional measurement affecting a fit tolerance.

A positioning device includes a support member configured to carry a workpiece, a plurality of pins positioned on the support member, and a plurality of telescoping mechanisms positioned on the support member. Each of the telescoping mechanisms comprises a driving member and a rotating member connected to the driving member. The positioning pins slidably pass through the support member and are pivotably connected to an opposite end of the rotating member. The rotating member rotates relative to the support member via the driving member to adjust an extending length of the positioning pins relative to the support member.

A metrological apparatus (15) is disposed for adjustment of an attitude of a workpiece (16) having an arcuate upper surface (17) relative to a rotary axis (C) of the metrological apparatus (15). The workpiece (16) is brought into a first rotary position (c1). A plurality of measured points within a measuring plane on the upper surface (17) is recorded. The workpiece (16) is moved into a further rotary position (c2) about the rotary axis (C), and again measured points in the measuring plane (E) on the upper surface (17) of the workpiece (16) are recorded. Based on these recorded measured points, the actual attitude (Li) of the workpiece (16) deviation from a specified target attitude (Ls) are determined. Adjustment parameters are determined, and an adjustment assembly (24) of the metrological apparatus (15) is activated as a function of the calculated adjustment parameters to adjust the workpiece (16).

A motorcycle starter contact alignment tool is configured to be an adaptation of a solenoid tool plate incorporating a threaded aperture to adjustably control the advancement of a threaded rod and a contact jig. The threaded rod is intended to depress the contact jig, having an alignment face which coincidentally contacts a pair of electrical contacts within the solenoid housing, so as to properly align those contacts prior to being tightened in position. The threaded rod is provided with a handle to facilitate the turning thereof.
