What is Jig Notching?
We build and check our Roll bars and Roll cages on jigs that we have built. They duplicate the inside dimensions of the particular vehicle. Each bar is placed and located on the jig as if it were in the vehicle. This allows us to make sure each bar is bent correctly and cut to the right length. This also allows us to completely fit each bar to the main hoop and floor as if we were installing it in the car. We are notching the ends of the bars where they meet up with the main hoop. All the fitting is done, and done in the correct location, as the bar is designed. We also scribe the main hoop as to where each bar is to be located. This allows you to just weld the plates to the floor, locate your main hoop in the car, line up the other bars with the scribe marks, tack it in, and then weld it all together. We like this process so much, that all the roll bars and roll cages we install in our shop are jig notched. We have found that it cuts our installation time about in half.
