Just an update on this. My id and ego seem to be in a constant battle between what "should" be possible and what actually materializes from my occasional forays with my junkyard collection of metal working tools and my informally acquired skill set.
Your post, Dusty, is comforting. You see, I had to make the executive decision to expeditiously continue our path forward on this project due to the fact that "green bug" is fatiguing faster than I am making progress on clearing Rusty out of the garage.
Therefore, it is now the plan to continue forth with our crew-tubed cage and, at least in spirit, continue with our race car-like visions. I am not sure if the final product will include a fuel cell or tank, but that decision will have to be made another time. The real consequence of this decision is freedom from the rulebooks. The purpose of this vehicle will be for driver training, prerunning, and recreation.
I have since lifted Rusty from the floor and placed it onto jack stands in preparation for suspension design and assembly.
I harvested the torsion bars out of the type III rear end only to be disappointed by the diameter. They are the same diameter as my growing collection of stock bug torsion bars. Also, they are of intermediate length. My joy of completing my torsion bar collection was cut short when I realized that I now have a decision to make.
I have my choice from stock short, intermediate, or long torsion bars. This choice is further complicated by the plethera of spring plates that have accumulated on my spring plate shelf. Single or double are the choices.
My intuition takes me directly to long torsions and double spring plates due to my experience with them. My logic tells me that the longer torsions will allow more degree of flexibility over the long term before failing and that two pieces of spring plate metal is better than one.
I have menacing thoughts of a more progressive rate with the short bars. This is haunting me because on the surface the highly progressive spring rate seems ideal, but dampening a highly progressive spring rate with the conventional, zero bypass, dampening mandated by my [daughter's] budget would seem to be a complex balance of motion ratios and shims that would be hard to perfect on the first try. In addition to that scrimmage, the flexibility of the single spring plate seems advantageous at times over the strength of the double.
I have decieved myself before so, despite my ambitious timeline, I thought it prudent to open up my decision for scrutiny. I am at your mercy, STF... And so is the fate of my daughter's future driving experiences.
