Figure 1 on the enclosed sheet, shows the third angle orthographic projection details of the parts that make up a pipe vice assembly. In assembly, the screw, part (3), is inserted into the base part (1) from above. The moveable jaw part (2) is then attached to the screw from below. The handle part (4) passes through the hole in the screw and is secured by the handle ends, part (5), on either end.

(a) Draw, FULL SIZE, in either, first angle or third angle orthographic projection, the following views of the assembly: (i) A plan of the assembled parts. Show all hidden details. (ii) A full sectional front elevation on cutting plane 'X-X'.

(b) Show SIX main dimensions to include a length, a diameter, a radius and a metric screw thread specification.

NOTE: All fillet radii are 5 mm.
