If so, screws into pipe equals flow restriction in the pipe Won't make a terrific difference, but a 1/2 degree here, 1/2 degree there all adds up

BTW, any luck in your search for ducting/shroud/fan stand off material? And don't downgrade your setup, you did some really nice work with it

EMC2-

Well, not sure what you mean yet??
I added some images below. Are these the clamps you see? My other snaps were from a distance not very clear.







Let me know.
