These parts go on a concrete outlet structure. I didn't design it, just working off not so great prints. Some guess work involved. I'll post new pics as I go. First pc. is a cone shaped pc. for the bottom drain hole. 304 ss. Started with 1/8" sheet. Layed out & cut two halves, then bumped to shape. Tacked together. You can see the lines I drew for bumping, about 1" apart on large end. you can make the cone smoother or not by bumping closer/farther apart. Cone is 12"h x 9"lrg end x 3"sm end.


I still need to cap off the large end & add an inlet box to the side. Then it gets welded to a mounting plate that bolts to the concrete structure.
