Why is it old guys seem to be up late into the night....  rolleyes

Well Ross and I have been beating around some ideas for the front roll bar... and doing a little sitting in and checking...
the original idea I had has some drawbacks... a little narrow on the arms

Idea 2 shows more possibility... although this one is not the final.... I need to find a smaller radius die for the joggle...  but I think this one shows a lot of promise.  Just needs to start a little higher on the tube, and not be wider than the car  undecided .... learned a little about bending on this one.  Yes there will be bracing to the top rail and more tubes on the top, but the one in the middle makes it easy to hold it up. Target angle is 30 degrees.

why not to the top of the rail and a straight piece between the frame rails?  You could even offset the joint if you wanted a little deflection in the top frame rail in the event of a ahhh sh!%

Reliability and performance are highly overrated.

If you look at Stainless' avatar pic you can see how the canopy has a flat (horizontal) transition before it meets the vertical side of the car  (approximately 3" on either side).  Stainless and Pork Pie want to keep this horizontal area from the front of the car thru the canopy to the tail section so the roll bars need to be inside of the top bar similar to the second hoop example.

I know nothing about streamlined cars, but why does the upper frame have to be as high as it is (although I don't really know the actual height)?  It looks like it restricts the height and shape of the bodywork, especially ahead of the driver which determines his sightline (maybe I'm the only one who has problems running over flag stands.) It also looks like it would restrict exiting.  With proper trussing, the height looks as though it could be reduced.

the top rails are 24" outside to outside, the side rails are 16" top to bottom.  the top of the roll bar is apprx 9.5 inches above the top rails.  driving position is almost prone.  so, in positon with a helmet on, your eye level is just above the top rail/top of the body panel.  there is some rake to the car which helps line of sight.  Bob, I hope I am not giving away too many secrets/details.

Good to know.  My shoe size is 8 so I guess I would qualify although my sight line might be a bit short at 23".
the top rails are 24" outside to outside, the side rails are 16" top to bottom.  the top of the roll bar is apprx 9.5 inches above the top rails.  driving position is almost prone.  so, in positon with a helmet on, your eye level is just above the top rail/top of the body panel.  there is some rake to the car which helps line of sight.  Bob, I hope I am not giving away too many secrets/details.
I only see bottom rails and top rails.  What are the side rails, or are they not there yet?
