Bushing and Nubs
My friend needed some parts made for his commercial kitchen. On the right is a bushing for the donut forming machine. I chose lignum vitae because I thought it would be tougher than the HDPE I had on hand, and because the lead content of bronze would have been potentially bad to have near the dough.
The screw and washer in the bottom of the bushing prevents the bushing from jiggling out of its socket in use. The rubber band below it is actually the 'part' which it replaces.
The brass parts go nowhere near food. They support a folding arm on a deep fryer. The original nubs were just plug-welded in place. They both broke off. Hopefully these replacements last a little longer.
