Custom Built Frame How-tos?

[MonzaRacer]

Most of the chassis kits I helped build with used 2x3x0.125 mild steel, if we could get mandrel bent OK if not we could cut and weld and plate, or slice and form, then weld and reinforce every joint.
See if yo put enough cuts in a pipe it can be bent in circle, just don't cut all the way through.
If its not too wide some of new Crown Vic's have bolt in front cradles, pretty popular in street rod crowds.
Or mimic Fox front end or SN and use one of tubular k members.
Twintorino swapped in bunch of parts from Mustangs in their Torino's. Adapted lots of stuff and got awesome car out of it.
I like the book "How to make your car handle." By Fred Puhn.
Learned tons of stuff from that book, even how to build chassis some.
