With the base frame ready and the engine and drivetrain mounting taken
care of, it was time to start thinking about what would become the rest of the chassis.
I started by buying a JD2 Model 3 manual tubing bender and did my own
homebrew hydraulic conversion.
With the bender complete and some practice using a stick of 1" tube, I was
ready to try the real thing.
Rear of the chassis
I had decided to build the main cage portions from 1 3/4" x .120" wall
HREW tubing. I started by fabricating the main vertical cage hoop that would rest behind
the seats. To that I added a halo top hoop, and then began constructing front pillars.
I made temporary mounts for my seats to get an idea how everything would fit together.
After that I began the rear portion of the "bed" area. The rear horizontal hoop is
tied to the stock frame in six places. I then added two fastback bars for added
support to the rear of the cage.

With the main portion of the rear complete,
I started on the front by adding the hood line hoop. The height and slope of this
bar was largely dictated by the engine. With the hood bar in place, the rocker
bar was added on the bottom of the chassis and tied up fron to the hood bar and
tied in the rear to bed bar. Each rocker ties to the stock frame in four places.
Another support bar was added behind the seat area.
The front end was somewhat difficult to design but I eventually
decided on something and ran with it. I used some cardboard boxes to mock up my
radiator and allowed room to fit the winch up front. Bars were added to tie the
hood bar to the frame and the engine was further caged. I added a pair of Harley
Sportster H4 dual beam headlights. Stock filaments are 55/60W, but I may increase
power output later.
More tube work here and there....check out the pics.
