Fabrication Steps

Note: there are holes in the above diagrams which won't be torched until the hopper installation.

Prepare the hinge plates

Hole locations for the hinge plates

Welding the hinge plates

1. Punch 3/4" holes in 4 of the hinge plates as shown.
2. Weld a holey hinge plate, a non-holey hinge plate and 3 hinges together as shown.
   • Make sure the side of the hinge that sticks out most is on the top; this way it won't interfere with the hopper metal below when installing the hopper.
3. Make 3 more of these.

Mounting the hinge plates to the hopper metal

The bolts ready to weld

The hinge plates mounted to the side pieces.

1. Torch the hopper shapes.(See diagrams above) Grind away any excess slag.
2. Punch all of the holes shown.
3. Place 1/2" bolts thru the side pieces and weld them.
   • Make sure you are making them mirror images of eachother.
4. Bolt the hinge plate assemblies to the side pieces using a washer, lock washer, and nut on each bolt.
