I was just wondering, how do serious race shops fishmouth tubing for roll cages?
Most of the stuff I do is 1.25" OD x .049 wall, but what about NASCAR, NHRA, SCORE and the other guys with tube sizes up to 3" OD?
I've done it with a die grinder, done it with a hole saw, seen it done with an end mill, seen it done with a nibbler, seen pictures of joints cut with a CNC plasma cutter. But I have never seen anyone fishmouthing the roll hoop for a monster truck. Is it done with jigs and big cutters, or is it done freehand with a grinder?
Any insight you might have would certainly start an interesting discussion thread.
