3d cad

with a new rollbar

The new roll bar looks a bit lost behind the seats, prefer the old roll bar.

Sorry

Heres a quick update of my 3d cad. As some of you know i'll be getting a full cage with side impact protection installed, so I thought a good way of knowing what this will look like I've decided to model it on 3d cad. So far I have just got the heightened rear roll bar with a slightly decreased angle, and the front roll bar. I'm trying to make it so the roll bar is MSA compliant, as I'll be wanting to do a few hill climbs once the car is finished:



I still need to put in the rear roll bar stays, the side impact supports and roof braces.

I've crudely put on the roof supports and side impact bars as I am yet to learn how to accurately do fish mouths on inventor.



Feel free to tell me what you think.

thats looking nice Tatey,

i,ve seen some side bars that have a kink in them around where your elbow would be & so give decent elbow room & also mean you can join the tubes to the roll bar without the 90 degree corners, just an idea

look forward to seeing your car with a full cage fitted,

cheers

Taty,

If you follow the link it takes you to the MSA blue book which give you all the info you need for competition cages.

All the best with the build.

Cheers for the support lads.

Cheers for that John, I've been reading through the blue book, however it doesn't specify a few things, which I'm currently trying to clear up. If i don't get any definitive answers then I think I'll be getting into contact with MSA.

Andy, I'm defiantly thinking about having the side impact bar follow the lines of the car instead of being 1 straight member, the MSA specs don't specify if the bar can be kinked or has to be straight, so I'm currently trying to get the bottom of that one.

I think I will also be putting a horizontal brace across the front roll bar, as suggested by Ash. I just need to make sure it's at the right height to mean that it doesn't get in the way of any dials or the steering wheel. I was thinking of running it underneath the steering wheel, but I need to do a bit more research into that one.

Also I've now changed the rear roll bar so that it has a 90 degree angle instead of an 85 degree, so that it matches the front roll bar, which I think looks better.

I'm also unsure if the roof bars can have a kink in them like Slimtater has on his car.
