SASME Standards Clinic
The handout from Jim Homan's clinic on club car standards.

Addendum: Never use self-tapping screws for fastening the trucks to the bolster. Self-tapping screws expand the plastic and will interfere with the truck swivel. Which can cause a truck not to swivel thru a tight radius turn or turnout and cause derailments.
