At the hinge points I will be using hardened pins but I'm not sure of
a couple things.

1. how to size them (if someone could point to an equation let me
know) or I'll just way oversize them and forget calculating them.

2. should these pins be in bushings and if so what material should
these bushing be?


Machinery's Handbook has the information you need in the section on
plain bearings. Since this is a slow speed app, you're interested
primarily in the load bearing (pressure) capacity of materials rather
than PV (pressure x velocity) limits. Ability to run in the presence
of dirt is also presumably a consideration.
