On a better note, I think I am willing to try to make this a working model. I spoke with a chain company about their smallest chain and stuff, and I think it is reasonable to go through with it. I say that because the styrene will be spot on accurate by its very nature, and therefore it should work.
Well...here I go again. First let me say I would love to see this as a working model. That should dispell anyone saying I am being negative.
However, the chain is the least of your worries if you plan on making a working model. It is all about the TRAIN. The train is the single biggest hinderance to creating a model that functions. In order to complete the course with scale-like heights and elements, the train must be amazingly efficient. Bearings are not good enough unless the scale is a little bit larger and the track and support structure can handle the added weight by being extremely rigid. Regular plastic on a metal axle (Knex) is woefully inefficient. While our system (CoasterDynamix) allows good efficiency with light weight, it is nearly impossible to scratchbuild to the level of precision needed. We struggled with this for years. CoasterDynamix was originally designed using ball bearings. Then we found out that the variation in bearings was quite great (when trying to find free-wheeling bearings) so we had to go back to square one. In order to keep the scale appearance, whatever you choose will need to be very small and compact. It is possible to use N gauge or HO train "trucks", but you will compromise scale appearance in the process.
One of the reasons that there are very few working scratchbuilt models is because of these difficulties. The track structure, while challenging, is pretty straightforward using many off-the-shelf modeling supplies. Unfortunately, the trains aren't so simple.
Again, I wish you luck and would be happy to help in any way I can. I have traveled the learning curve many times so I might be able to save you a lot of work. Perhaps along the way we can both learn something.
