    Default Triangulating rollcage to front turrets

    Pondering about doing this to my car before it's painted. I currently have a Safety Devices 6pt rollcage (bolt-in type) welded to the floor, so it's not going anywhere.

    Is the competition car build manual the best way of doing this? Just bolt it from the front hoop to the gap between the turret and a bolted in piece between the horizontal and the horizontal mount:



    If I were to do this, I guess I could use 'saddle' clamps like these (defo for the top, not sure about the bottom as it would be at an angle?!):

    Or would I be better just profiling the ends and welding them to the front hoop? Or welding them to the turret? The only problem I can see with welding to the turret is that you wouldn't be able to get round the back of it to weld up. I guess you'd need to weld around where it comes out of the bulkhead so there's no real need to just bolt it in.

    To complicate things further I guess care would need to be taken to avoid the bonnet hinges.

    Ive always profiled the ends of the forward triangulation an welded them to the front cage legs, then tagged & welded them into the turrets, but thats on 106/205/C2's.

    But saying that, theres enough room on a Nova to weld or tag them onto the sides of turrets so to speak.

    Burgo has some good pics of this from his light blue loon

    EDIT: Good point on the bonnet hinges chap, if memory serves me right theyll be right in the way wont they?

    Yeah I was looking at Burgo's pics from the thead [url=http://www.pngclub.com/forum/showthread.php?t=136936&highlight=triangulation[/url] and seems to miss the hinges, depending on your front loop position I guess:



    Will F looks to have copied the build manual, which I quite like the way it's done, bolting it to the gap next to the turret: & also missing the hinges

    Cheers NovaSport, I found that while searching for pics too! The issue I thought of with doing that is it'll be very difficult to weld the diagonal piece to the horizontal as you won't be able to get the torch behind very easily?

    There's also CPs where he seems to have welded the horizontal to behind the turret, but not sure where the diagonal goes as I can't see it come in to the bay!



    Another robbed pic, Count Vaux Alot's rollcage before he started on it shows what I'm thinking of for the horizontal bars:

    Its a good idea if you aregoing to give it a proper hammering!

    Roll Centre did mine, but the hardest part is getting it all sealed up and looking decent where the cage enters the car!

    Yep, I'm just thinking of the best way to do it. I think a horizontal coming to the turret gap like Will's, then some triangles welded to that and the turret for a diagonal to bolt to.

    But should the diagonal go down to where the door bar meets the front leg, or where the front leg meets the floor?

    Will that wouldn't be a problem regarding neatness as I'd just weld it to the bulkhead where it comes out.
