Although I posted pictures of the frame rails to this site , I just realized that I have not posted a design for the chassis. This post shows the design – such that it is.
The new frame consists of all new material except for the cross-tubes used to mount the suspension pots. I could create new cross tubes but I am salvaging the old ones because they are very time consuming to recreate.
The following pictures are plans for the new frame. Beware! These plans are a work in progress. You will notice the absence of any devices to improve torsional stiffness. I have not figured out the best way to do this yet. I will post updated plans later, once I have done some deflection tests on the built frame . I will be aiming for about 1200 ft-lbs per degree, which according to the research I have done so far, appears to be the acceptable minimum for road use.
