‘52 Chevy pickup: new frame
Here is a pic of my ‘52 Chevy pickup with a Firebird subframe and custom rectangular tubing rear frame. Today I’ll show the construction of the main frame rails. I wanted to subframe the truck but didn’t want to use the old rear frame (very flexible). I simply took some measurements and copied the old frame with 2″x4″x.125″ rectangular tubing (later I added an x-member made from 1″x2″x.125″ tubing, but that will be another post).
I roughly copied the kickup over the rear axle with 45 degree angles. To make a 45, cut each piece with 22.5. Below I show the pieces for one rail and the other rail tacked.
