Thanks to everyone for their incredible guidance and feedback. It sounds like the technic rod acts as the pin for the boogie and that is what I was really trying to understand. Railbricks is an awesome resource! Thanks again and I can't wait to start my new project, I will post pics as it goes.
Also, one of the other reasons I need this to work is because I am looking to build a garden railroad out of lego gauge trains and it will have switches, dips and lulls.
