Diagrams

The grate is 6 by 3 feet (91.4 by 182.9 cm). Made from 33 pieces of half-inch rebar, each three feet in length. These pieces of rebar fit into a frame made of 1/4" angle. There is a one-and-a-half inch between each of the rebars, which means 2 inches from the center of one to the center of the next.

Fabrication Steps

1. Prepare the 6' pieces. One needs nuts welded to it, where it will attach to the grate supports. The other needs holes torched in it where it attaches to the hopper supports.
