#Torch the hopper shapes.(See diagrams above)
#Torch the hopper shapes.(See diagrams above) Grind away any excess slag.
#Get one of the side pieces and clamp the holey side of the hinge plate to one side of it.
#Punch all of the holes shown.
#*Make sure that when the side piece is in place and vertical, the hinge pins will be facing down (otherwise they could vibrate out).
#Place 1/2" bolts thru the side pieces and weld them.
#*Clamp it  so that it has just enough clearance for the other hopper metal, so there will be as small of a gap as possible once the hopper is assembled.
#*Make sure you are making them mirror images of eachother.
#Transfer punch thru the holes using a 1/2" transfer. Put the transfer in the bottom of the hole, near the edge of the hopper metal.
#Bolt the hinge plate assemblies to the side pieces using a washer, lock washer, and nut on each bolt.
#Mark both pieces to ensure this exact plate goes back to this side.
#Repeat the above steps for the opposite side of the side piece, with a different hinge plate, Still insuring the pins will be facing down.
#Repeat steps 2-4 the same for the other side piece. Make sure that it will be a mirror image of this one, not oriented the same. In other words, prep the hinge plates on the opposite side as before.
#Punch all of the 1/2" holes where you center marked.
#Take one of the punched side pieces, and flip it over, so that the side with all the marks is touching the table.
#Place 1/2" bolts thru the holes and weld them.
#Do the same for the other side piece.
#Flip the side pieces over and match the put the corresponding hinge plates onto each set of bolts.
#Bolt them down tightly using a washer, lock washer, and nut on each bolt.

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.
