So I was thinking of building some radius arms out of DOM when I do my sas. Any thoughts. I was going to buils them similar to the duff or cage arms. And use Hiem joints where they mount to the frame and make them adjustable with a lock nut so that they don't have to be computer built percise. I have acess to all the nessascary tools and software to fab them up. Anybody else build their own?
