Rollcage Construction

[charlie835egg]

Hi all,

 

First off I'm part of Rover Scouts and we have a amatuer offroad racing event called BASH.

 

What you'll all find intreging is that we have an old KE70 with a 6" lift, Mazda VC engine and running gear. I'll have to post a pic of the view of the rear lift. It looks so wrong.

 

We have stringent safety specs (its CAMS really) and we need a 6 point rollcage. Was talkign to chris the guy responsible for buiding it and he was saying we're goning to have to cut the roof to do some of the weld for the cage. I striaght off said BULLSHIT. then he asked how and I had no freaking idea. The weld I'm talking about is this one in the top of the pic of Fook's rollcage.

HOW DO THEY DO THE WELD ON TOP BETWEEN THE ROOF?

 

This has got me perplexed. And I'm sure the solution is not a hole saw.

You cut a hole in the floor and drop the cage through.

don't weld any non nessesary before you have welded all those seems you have to weld at top side.

 

some examples of good rollcages.

there is a couple of ways you do it, but the easiest is to cut holes in the floor where the legs are going to sit, so you can drop the main hoop and front legs down far enough to weld it,

it's a good idea to tac weld all the roof bars in placebefore you drop it down to weld it, so you're welding them all at once.

then once you've done that it's a matter of lifting the cage back up and putting the foot plates under the legs to stop the cage dropping down.

when you've finished all the welding on the rest of the cage, just weld the peices that you cut out back into there holes, this is the hardest part unless you can turn the car over.

On the speedway cars we cut the roof off, drop in the cage in three pieces (we run bumper to bumper, so centre, front and back), then weld the roof back on. Its piece of piss really compared to welding the cage together inside the car.

 

Just my $0.02

Man holes in the floor. That's so simple it could work. Thanks for that gem of knowledge. This'll save cutting off the roof. Thanks all.

 

Thanks for the link Toycrash, its handy.

 

Will get some pics for you Ted. But basically its a masicured KE70.
