Hi Guys
This really has been about 7 years in the planning/dreaming.
First start was with a full frame work welded up and a plan to clad with aluminum, after a few years of sitting the steel frame was too rusty to bother with soooooooo.......
The new plan
Im building the body in a friends barn and have a forklift/tractor to lift the heaviest panels
Building to my own design the base frame is steel I beam cut in half and welded to make a solid base with two lifting points at the rear for a forklift to slide in too,
Depending on how it all goes I may adapt the frame to use trailer lift jacks to remove it from the truck.
The panels are a simple foam sandwich comprising of Gelcoat, plywood, 45mm refrigeration foam, plywood and Gelcoat, the edges are all high density foam to provide a point to screw in to. Also on the bottom there is a 5 x 50mm aluminum strip inside the panel to provide a solid fixing point.
Total panel thickness 60mm
Panels are bonded to the frame with sika 252 and also M8 bolts at the base for extra strength, also the joins and roof are bonded with 252 and screwed
all in all a pretty solid construction
