That looks like it works good Dave!

Thanks Mrs.CP. After using 5 hinges, it worked great to finish the piece in the photo. But then I got to the 2 foot long sections of the sluice. The wood handle snapped. I gotta unscrew some boards, and put 2 boards at once for the handle, then secure it again.

(won't have the sluice finished by the weekend.)

Oh well.

Very bendy!!

I thought about building one of these when I was making a clean up sluice a couple years ago. Another option, and the one I used, was to nicely ask a roofing company to make some bends for me. 10 minutes later, my sheet metal was bent to my specs.
