My son helped build the first pass on creating the main hoop of the cage. My respect for guys who fabricate race buggy's and other race car cages has gone way up - this is complicated stuff - and DOM tubing is pretty unforgiving.
Built the roll cage such that the body would still come off. Did a nice job. But removing the body was really tight - it'll need a little adjustment before we put it back on.
Here it is after the final seat belt bar and cross bar are in place. Everything is tack welded - I'll have to finish the rest of the welding once my gussets arrive from Speedway Motors.

ReplyDeleteCan you give some details on the requirements of the cage? Why did you choose to have the main hoop go straight across? In a lot of class 11 bugs, it looks like the main hoop has an extra bend across the roofline to match the contour of the car.
DeleteThanks for the question. Ideally it would be great to have a bend in the very top of the cage. However, I did it that way mostly out of simplicity. The roof line is not straight, but keeping it straight doesn't cause any problems. This is the first cage I have ever built. Measuring the angles and keeping everything in-line is much more difficult than one might imagine. So, to keep it simple, I went with the simplest design that accomplished my goals.
DeleteLastly, you can read the requirements of the cage on the SCORE website. They have all the rules spelled out clearly in the rule book. Further, I contacted Art Sevedra with any question which was unclear. He is the one that will be inspecting it.
