A universal tram is provided for aligning machine tools. The universal tram includes a slide rail, featuring a rail along its length, to which a clamping coupler attaches. In turn, the clamping coupler attaches to the indicator holder. The indicator holder is configured to hold an indicator. The slide rail is configured for direct attachment to horizontal and vertical milling machines, for example. Optionally, the universal tram also includes a machine adapter and adapter plate. The machine adapter serves as a base block for positioning a measurement or tramming device on a machine tool to which the slide rail does not directly attach—a horizontal or vertical lathe, for example. The adapter plate allows for the height of the machine adapter to be adjusted by an amount corresponding to the thickness of the adapter plate. Further, a method of using the universal tram is also provided.

A rear shifting and drive system, frame drop out, derailleur hanger and derailleur alignment tool provided with an axle attachment adapter/structure, a moveable collimated light source, and a collimated light source positioning linkage. The axle adapter/structure is attachable to a bicycle wheel axle and is rotationally moveable about the axis of the bicycle axle. The light source is moveably coupled to the axle adapter/structure by the light source positioning linkage, to move in a direction substantially parallel to the axis of the bicycle rear axle. The light source is positioned to shine the cross laser simultaneously on the axle or plane of the axle and the system components of the shifting and drive system. A visual vertical alignment of the cogs of the cassette, and derailleur jockey wheels, to each other in each shifting position, and relative perpendicular to the axle or plane of the axle provides an easy visual aid in assessing the relative positions and orientations of the components. As such, worn, damaged, bent, broken or maladjusted components of the shifting and drive system can be assessed and adjusted, repaired or replaced without disassembly of the shifting and drive system.

A magnetic pipe square level comprising one or more magnetic members fused to an angle iron, a square that consists of a base member and a perpendicular member, the angle iron fused to the base member, one or more bubble levels attached to the square oriented in line with one or both of the base member and the perpendicular member, an anchor point attached to the perpendicular member, a track for a string line underneath the tip of the angle iron, a notch at the end of the track where the base member and the perpendicular member intersect and one or more sets of tick marks along an edge of the perpendicular member providing a reference point for a measurement.

A trim square may include abase and a triangular main body defined by a first leg and a second leg that form a right angle at an intersection therebetween, and a third leg extending between distal ends of the first and second legs. The base may be operably coupled to the main body via a retention element at one of the first leg or the second leg. The main body may extend in a first plane, and the base may extend in a second plane substantially perpendicular to the first plane. The base may be movable relative to the main body in the second plane.
