Title: Building a 10 point roll cage Post by: Flenne on January 15, 2008, 19:20:35 pm Hi draggers..
Im giving it a try, to build a roll cage on my own. The question is where i mount it on the floor. Does anyone have some pics that shows your cages. Mounts, tubing and especially where you have the links to the floor? Hope you can help. Have a 1966 sedan. Best ET 12.66 at Vandel DK. Couple of years ago..First time with slicks and after the 2nd run it nuked... ::) With radials it had a best ET 13.04. Hope to see you at Gardemoen Best regards Flenne ;) Title: Re: Building a 10 point roll cage Post by: Neil Davies on January 16, 2008, 10:52:44 am Worth checking out your national rules for competition - even if you are definately not going to run the car in competition at this point, you might decide to later on!
In the UK at least, you need to mount the cage onto a 150x150x3mm plate, but it doesn't have to be centred on the plate! It was recommended to me that the footplates are welded to the floor and then drilled through and bolted on the 4 corners to a matching spreader plate on the other side of the pan. There are two ways of mounting the cage that I've seen - one is to fix it to the floor, the other is to fix it to the heater channels. Both have positives and negatives. Mounting to the floor is the way mine was done, with the B-post foot plates bent to accomodate the shape of the floor. It's strong, but on a street car can intrude too much into the car space. Also, if the cage is custom made to fit tight into the body, there is no way of getting the body off afterwards. (The new owner of my racecar found that out, so he cut the heater channels away to remove the body... and thne wonered why the body folded in half!). If the cage is to be fitted to the heater channels then the plates need to be bent to form boxes on the channels and then the ends boxed in. Problem comes if the heater channels are a bit rusty, if the car does roll the cage could break away from the channel.

In the rear its probably no problem, but the front... Holy s... Its way too far from the door to fit. You dig? Dont know. My first time. Im a welder at work but just have to get it right if i have to race with you guys... Hmm. 11.xxx this year i hope.. :P
CHEERS 8) Flenne Title: Re: Building a 10 point roll cage Post by: Neil Davies on January 17, 2008, 09:53:00 am Best thing to do I think would be check out a load of racecars and see how they're done. Inch Pincher 4 for example has a glovebox lid that is narrowed by an inch or so to let is open past the cage! DOn't forget to mock it all up with the doorpanels and seats in place so you know that it'll fit! ;)
