quick roll bar question
hey all just a quick-un, i plan to make my roll bar and obviously weld tabs on to allow my harness to be bolted on, question is... do i need the bars that go to the lower chassis to allow it to be bolted just near the fuel tank area?

I would put backstays in. As you would be moving if you were unfortunate enough to roll the car, a single hoop on its own would be more likely to deform as angled forces would be acting against it.

All this done correctly, most probably the frame will suffer most turning turtle. In this picture you can see that the roll bar sits on bases made of 5mm plate that spreads the load over a large area. The frame has added framing that is gusseted (4mm plate) to other chassis parts fitted to take the bases and was weld fast on that. Note that the roll bar also has a camber in it for strength. The lower tube where the harness bolted to is close to base of r/b and immensely strong (no lever effect) and made from 4.5mm wall steam tube. Roll bar was made from 63mm diameter x 3.8mm tube. R/bar welded to bases with 5 staggered filleted stainless steel welds for strength. and here is the completed job. Last edited by Wynand : 7th June 2012 at 07:52 AM. Reason: added pics |
