The pictures look great, and that manifold can pass muster as a work of 
art...but does it break the design rules that I've learned from FlyRotary?


1) The pipes are welded to the outside of the flange.  Isn't this setup 
prone to cracking at the flange?

2) There isn't any built in stress relief.  Or is that the point in all 
the bends?
