This is a simple how to build a roll cage. This cage is made to fit my Impala.
To build a roll cage you need:
* Styrene rods
* Knife
* Pensile
* Ruler
* Tape
* Paper
And it's never bad to have some references.
This is the reference I used.
This cage was made in 1 3/4" chrome moly. So I took the closest rod I had, 1,5 mm.
1. Measuring
Let’s start of with making measurements. For me it was easy. I measured the with of the roof at the impala just to see how wide it could be at a maximum. It was about 50mm.
The with of the cage needed to bee 61mm other wise I must squeeze it in place.
I also draw the side supports.
When I am done with that I draw another one that looks the same.
And cut it out.
Then I test the paper cage in the car, to see how it will fit.
2. Bending
I start with taping the styrene rood on to the paper.
And then I start to bend the rood as close to the drawing as possible.
After that I remove the tape. And test the cage in the body (no picture).

I do the same with the rear supports and this is how it looks with one of the rear supports.
The last step is to glue the cage to getter.
I am going to chrome the cage later on and put on some soft material on it so it will look like this.
I got the reference from
I hope this will be to help fore some one.
