I was at the Mechanical Engineers today getting the roll cage cleared and legal.
When I last posted the pictures of the cage, there was concern about the strength of the alloy seat boxes and how much weight they could support. It didnt matter to much because the rear support bar is connected to the chassis, but I posted the question to the engineer about whether or not the seat boxes could support much weight as they don't look very strong.
After looking in the guards from outside the car under the boxes. Suprisingly he explained that if a rear hoop was tied into just the seat boxes and done correctly, those boxes would take quite alot of weight because of the design of the thin sheet metal that is attacked to the box and how it's tied into the body. I said that it looked thin and weak and didnt look very strong at all, but he was convinced that those boxes could support a roll over hoop just fine and having my cage tied into the chassis was not really needed but did provide added strength.
I said that I thought they could collapse easily to which he replied yes its likely probable, but not a great deal, and if they did collapse, the way the cage is designed , the front hoop should then raise upwards and provide more force upward into the roof keeping it off the passengers. At this stage my head began to spin.
I am no Engineer and don't argue things that are out of my league butI am curious at what everyone else thinks of his opinion and do they understand it better then me.
Cheers
