Compound cuts for inlet manifold

[deezee]

Its a slower process, but I made a jig for my manifold to help. Clamped the flange in place and offered up the cut tubes. Tweaked them a little as compound angles are a swine. Had to redo a couple, marking the incorrect tubes to get a better cut next time. Then once I was happy fully welded it. Knowing perfectly the tubes were all in the correct place and angles were correct. I've attached a photo from when I did it.
