Well ive decided its going to be 25mm core floor pans and 10mm core for most of the rest with a few areas of honeycomb (on top of crumple zones).

Awaiting to rent a unit so i can strip the interior of the puma properly to get the measurements i need for the CAD work to begin. Then its design it in CAD.

After that its build a jig table to put the car on to fix the suspension points in space relative to the car, then i can take the bodyshell off and with the suspension points all fixed in space, ive got a practical reference point to work around as i part assemble bits of the chassis in foam ready for moulding.

Its one of those projects that will have long periods of little visible progress then spurts where things come together real quickly.
