Thanks guys, will be having a bit more practice with Tig and see how it goes. Know exactly what you mean about twisting, it’s always amassed me how much a weld can pull. Going to get quite a bit of practice and there should be plenty of scrap at the end of it, it’s been a while since I have bent any tube. Still not decided if the cage for the Mog will be made out of Tube or box yet. In the old days everyone seamed to just use 2” Blue Band tube for their cages and if you wanted one a bit stronger you just upgraded to Red Band, what’s the norm (if there is one) for a challenge motor? I think the ARC green book still specifies Blue Band but I can’t find my copy I’ll have to look at their website.
Only got No7's left now and they a quite a bit worn, think I need to pay a visit to BOC
