Alrighty... I had not planned to try to show the sides till I had more parts made, but now I have a question so I will show where I am headed.
First Lemming John, the seat back and floor are built with 1.5 x 1 x .125 square tube. The seat belts are 7.75 apart. The original Bockscar belts came together through the seat and pinched our necks... the first modification of that had about 2 inches of space between the belts... as they routed between the seat supports... still pinched the neck... These will come straight over the bar on the outsides of the seat back tubes at about the same width as my neck.
The cage... thanks Rex, strong is where I am trying to go. Please see pics below... the diagonal is a measuring device, not the tube that will be used. There will also be a diagonal from the front to the top that front bar where the front hoop attaches. Too much trouble to put it all back together for the pictures, but everyone should get the idea of where I am going.
The question... see second pic... when building all of this should I weld in that vertical, then weld in the diagonal. then weld the front vertical or should I assemble it all together and then weld the perimeters to the bottom rail. I searched the crap out of the internet, looking for that answer, everyone shows finished product where tubes overlap at intersections, but have not found any process pics anywhere. My first thought is one tube at a time and build forward so each tube has 360 degree welds. Y'all feel free to chime in and give me a hand here.
Forgot... Jerry, you need to tram after a big head tilt?
Probably will just use the marks till I get all there angle copes finished and I need the level of precision that a well used old Bridgeport can do.... +/- .001ish
