ok, let's talk exocages.
why do i want an exo, versus an internal cage, you ask? well, i don't care too much about my sheet metal being straight, however, i need it to continue to be functional. within a few months of eachother i killed two doors and replacing doors gets expensive and more than anything, annoying. while i don't care about if the metal is straight, i do want it to at least resemble the lines of a straight truck. so, i wanna protect it and put the exo on.
here's what i've thought up for a basic pattern:
the plan is to weld the doors permanently closed, cutting a shape out of them resembled by the gray. the gray is a "soft" door and window which, to open, you unzip. the hard top will be replaced with a soft top, but, while it'll be a really snug fit with the cage, the hard top could potentially go back on. i doubt the hard top will go back on tho, because i'm trying to not gain much weight by doing the exo - simply loose some door sheet metal and the hard top, while gaining the exo, thereby breaking even.
i'll mount the spare on the roof (the exo will cover the whole top - similar to a roof rack), and i think i'll fab up a crane that will fold down and lay flat on the roof rack so that it can lift/remove the tire from the roof.
the tube that crosses the door along where you'd step into the truck will probably be removable - at least on the passenger side, and i'd simply install it when i go wheelin. this is just so that tree trucks can slide right on down the body, rather than getting hung up there at the door. we'll see, tho, when i build it if it'll be too difficult to step over.
the hope is to do this as an independent study for school, and i'd study how it might load in a roll over, how the heat affected area from welding might affect it's strength. it would basically be a hands on study of statics, material mechanics, dynamics, manufacturing processes, etc.
your thoughts, please.
