That looks like a good site. I bookmarked it for future reading.

I welded it up last night. I tack welded the inner seam on top and bottom, then made sort welds across the gap letting it cool inbetween welds. This worked great. It also cause less heat distortion of the intended bend.

Thanks for your help.
