I posted here after desperately trying to find some wheel assembly schematics and due to everybody's help I found what I needed and produced one of the coolest things my school has seen. Now I have just been given permission to create a 3D scale model of a woodie and I cannot seem to find any layouts I can look at to either replicate an old favorite or to just get ideas as how to design my own. Any help will be appreciated and just remember... you would be helping a budding engineer that doubles as a roller coaster freak.
