How to weld the frame pieces together
*Using the welder, weld 1/2-13 nuts to the 2 round holes of one of the 6' angles on the outside surface.
 
*Weld the two 3' and two 6' angles together to make the frame. The short pieces are sandwiched between the long pieces as shown. Make sure the holes you torched are on the outside, ie. not where the rebar will be welded on top of them.

The grate
*Weld all of the rebar inside of the frame. It would help to find some 1.5" spacers laying around the shop so you can place them between the rebars quickly and be sure they are square. Nuts and hydraulic fittings might be the right size.

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.
*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.
*Torch the holes according to the diagram, and grind off all the slag.
*Weld the nuts to the piece with the round holes, so the nuts are on the outside of the angle. Make sure you protect the threads with some nuts.
*Weld the angle together to make the frame. The short pieces are sandwiched between the long pieces. See the diagram. Make sure the holes you torched are on the outside, ie. not where the rebar will be welded on top of them.
*Weld all of the rebar inside of the frame. It would help to find some 1.5" spacers laying around the shop so you can place them between the rebars quickly and be sure they are square. Nuts and hydraulic fittings might be the right size.


*Weld the cross support (the 1/4 x 2 flatbar) in centered and perpendicular to the plane of the frame.
*Weld the cross support (the 1/4 x 2 flatbar) in centered and perpendicular to the plane of the frame.

Part Information

  • The soil grate prevents overly large chunks of soil from entering the hopper.
  • The soil grate is mounted to the hopper supports and the grate supports.

Tools Required

  • Welder
  • Angle Grinder
  • Clamps
  • Torch

Materials

  • [2] 1/4”x2”x2” angle, 6'
  • [2] 1/4”x2”x2” angle, 3' (2)
  • 1/4”x2” bar, 71.5”
  • [33] Steel Rebar, 1/2" diameter and 3' length
  • [2] 3/4" Steel nuts

Steps

  • Torch the holes in the two 6' angles as shown, and grind off all the slag.

Where to torch the holes on the grate

  • Using the welder, weld 1/2-13 nuts to the 2 round holes of one of the 6' angles on the outside surface.
  • Weld the two 3' and two 6' angles together to make the frame. The short pieces are sandwiched between the long pieces as shown. Make sure the holes you torched are on the outside, ie. not where the rebar will be welded on top of them.

  • Weld all of the rebar inside of the frame. It would help to find some 1.5" spacers laying around the shop so you can place them between the rebars quickly and be sure they are square. Nuts and hydraulic fittings might be the right size.

The grate

  • Weld the cross support (the 1/4 x 2 flatbar) in centered and perpendicular to the plane of the frame.
