When I need rib material for side x side guns and rifles I decide upon the contour of the of the rib that I want and the wall thickness and then calculate the diameter of a steel tube that has that or near that contour, (say 2 inches diameter) and then I buy (usually from eBay--although it will sometimes take a day or two to find someone selling it) seamless thin wall high strength tube lengths (say .049" wall thickness) that are scrap from the shops of automobile race car builders. I think all of the times that I have purchased these tubes it has been from some of the North Carolina race car building shops. Really nice and very thin wall "stuff".

Kindest Regards;
