Figure 1, on the enclosed sheet, shows the first-angle orthographic projection details of the parts that make up a table clamp assembly which holds a work piece in place for drilling holes or inserting other details.

In assembling the parts, the arm (2) is aligned with the body (1). The work piece (4) is placed within the space between the arm of the body (1). The M10 bolt (5) is passed through the hole on the body (1) and through the arm (2) and secured in place by the M10 lock nuts (6). The handle (3) is situated through the M8 bolt (5) which tightens the body (1) and the arm (2), keeping the work piece in place.

NOTE: All fillet radii 3 mm.

Draw, FULL SIZE, in either first-angle or third-angle orthographic projection, the following views of the assembly:

A FULL sectional front elevation on cutting plane "X-X".
