Question on roll cages

[tatocorvette]

Hello,

  Seeing Randy's work and other folks working with metal has inspired me to try it again.  I did some very simple brass work over a decade ago but I need a fresh start.  So I'm thinking on a simple project: Adding a simple roll cage to a C7 Corvette for use in a drag strip.   My idea is something like this: (Don't laugh at my drawing skills... well yeah go ahead and laugh). I took the idea from watching too many Youtube videos on home made drag racers. 



I started by doing the main roll bar and soldered a cross bar to attach the seat belts.   This is 3/32 brass rod.  The solder joint needs some cleanup but this is my first solder in over a decade.   Don't worry about one side been longer.


The rod is  3/32".  In 1/24 scale will be 2 and a quarter inches.  I think that is getting into the too thick territory. 
Now my question is, would it be possible from the real point of view (in terms of safety and or regulations)  to have that as a roll bar and the other parts in 1/16" (which will scale to 1.5 inches)?  
Or do roll cages need to be the same size all around?
I have some 1/16" tubing and since the other parts are only lightly curved I think I can use that.

Here is a mockup on the interior:



Thanks,

Check your references but 2" seems a bit large to me. From my research most cages are 1.5" with most of the structure the same size tubing.  I'm sure there are exceptions.  I have built some elaborate cages from styrene rod.  If you have the skills to work with brass, I do not, then solder on!

Thanks JC!

The more I look at it the more I think it is too big. I think I'll redo it in 1/16". I will also redesign the front bars based on another video I saw. Gotta stop watching Youtube  

Your cage looks really good.  Too bad roll cages are hard to see once finished and installed.

Thanks,
Ismael
