Crafting a Basic Cotter Pin Joint for Novices. To build a simple cotter pin joint, start by assembling all required materials and tools. Gather a metal rod or bar, two flat washers, one cotter pin, and a pair of pliers. Begin by threading the cotter pin through one washer, leaving about 1 inch protruding beyond its surface. Next, slide the other washer onto the end of the rod, followed closely by the cotter pin. The cotter pin should now be threaded through the second washer as well. Hold both washers firmly in place using your pliers and carefully bend the cotter pin to secure it within the joint. Finally, use your fingers to tighten any remaining slack, ensuring a snug fit between the washers and the rod.
