OK, where did we leave off? Oh yes, the burner duct support bracket is finished at this point and in need of a duct cradle bracket. The duct cradle’s job will be to evenly support the afterburner duct while still allowing it to “slide” back and fourth during it’s heat expansion cycles. This is super important or else the expansion will bend the frame and possibly push the turbo out of alignment.
I decided to build the cradle out of 3/16” thick x 1” wide 304 stainless steel bar stock. The bar was carefully formed to match the contour of the burner duct which should afford the most support.
