i had a bit of an accident in the GF's 1.7 VCT Puma recently. I have replaced it with a different car and have decided to repair and track the Puma.
depending on how it goes i am thinking of entering the Time Attack Series here in Ireland. I am just wondering does anyone who where I can get a bolt in roll cage for a Puma?
Thanks

This the way I did it in the last cage I fitted, (previous ones were bolt in)it also means you have to double skin the floor when you weld in the floor plates minimising the risk of it punching through the floor in the event of a roll. It's tricky for sure and a reasonable level of welding skill is required but with some care and patience it's possible to do a good job. Also most poeple (myself included) are not building the car for a specific race series so it doesn't have to be FIA or MSA certified it's just got to be strong enough to increase protection for a trackday roll/shunt it only needs to do this once and do it at much less speeds than a FIA certfied cage designed to do, I've done a bit of grass track racing in the past and these cars generally don't have a lot of cash lavished on them so all types of cages are cobbled together usually on mild steel box section rather than CDS and dispite some spectacular crashes with cars often cart wheeling I've never seen anyone badly injured due to the structure failing. I being lucky enough not to be involved in a roll myself but I feel better knowing that at least some effort as been made to increase the level of protection, even if it's simply box section welded in to strengthen the existing factory saftey cell it's got to be better than nothing, it doesn't need to be a WRC rep to do the job.

Have a look at their website

without the full weld, the cage has a stress raiser that will allow the joint to peel apart, since this joint is very close to your head there is a good chance of getting wacked on the nut by a heavy piece of tube, so I would say having a part welded cage is more dangerous than none.

Sorry Warren but that's if I've understood you correctly, that's bad advice - especially if for a competition car. The welds between the main hoop and the A post pillars need to be all the way round the A pillar tubes. The only way to do that is to have holes in the floor of the car I think. You are right that you can weld the rear section together to make a "half cage" for the back of the car, but as far as I'm aware there's no other option for the front section. Certainly with my rally car that's what I had to do - a scrutineer will often check welds go all the way round with a mirror, and insist on holes being cut in the roof if necessary to complete the welds.
If it's for a track day car rather than MSA car you can perhaps take the route you suggest - but if you do have an off, there is an increased risk of the cage breaking and leaving a broken sharp tube end moving around inside the car near your head. In big accidents this can and does happen with motorsport cages if they're not well fitted - cross braced door bars are a particular source of this happening, which is why they are very often gusseted to increased strength, and are sometimes designed as two parallel bars welded together rather than a joined X.
Also cutting the floor doesn't add weight because you should put plates under the cgae tubes anyway to spread the load - which cover the holes. Job done.

You dont get me the access at the rear end to do the main hoop all round is better than at the top of the front pillars where theres no space, even with windscreen out. The idea being you weld front fully, then lift front and roof into place, fit main hoop and weld from there.
Obviously the cage has to be designed to enable you to do that and some aftermarket cages may not have thought it through that far.
