== Fabrication Steps ==
*Weld a holey hinge plate, a non-holey hinge plate and 3 hinges together as shown. Repeat for a total of 4 holeplate-3hinge-noholeplate welded assemblies. Note to make sure the side of the assembly that sticks out most is on the top; this way it won't interfere with the hopper metal below when installing the hopper.
===Prepare the hinge plates===
[[Image:hingeplates.jpg|thumb|200px|Hole locations for the hinge plates]]
[[Image:weldinghingeplates.jpg|thumb|200px|Welding the hinge plates]]
#Punch 3/4" holes in 4 of the hinge plates as shown. The hole locations are not critical.
#Place three hinges between one of the holey plates, and one without holes to weld.
#*Make sure the plates are a 1/2" apart or more, otherwise the metal won't hinge enough to attach to the hopper.
#*The pins inside the hinge should all be facing the same direction; these will need to be facing down when the hopper is erected so that the pins won't jiggle out over time.
#*On two of the hinge plates, the pins should face right, and the other two, they should face left, for the reasons stated above.
#*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.
#Plug weld thru the holes in the hinges to the plates below, joining all 3 hinges to each plate.

[[Image:mountedhingeplates.jpg|thumb|200px|The hinge plates mounted to the side pieces.]]
#Torch the hopper shapes. (See diagrams above)
#Get one of the side pieces and clamp the holey side of the hinge plate to one side of it.
#*Make sure that when the side piece is in place, the hinge pins will be facing down.
#*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.
#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.
#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.
#Do the same for the other side piece. Make sure that it will be a mirror image of this one, not oriented the same.
#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.


See [[Hopper Installation]] for how to mount it to the machine.
*Weld the no-hole plates of the 4 plate-hinge-plate assemblies to the sides of the front and rear hopper plates.

  • Insert then weld the 1/2" bolts to the side hopper plates such that the bolt heads would be inside if the hopper were to be assembled.

The bolts ready to weld

  • Cut the 24' bar into 8 sections of 3' length
  • Punch 3/4" holes in 4 of the hinge plates as shown.

Hole locations for the hinge plates

  • Weld a holey hinge plate, a non-holey hinge plate and 3 hinges together as shown. Repeat for a total of 4 holeplate-3hinge-noholeplate welded assemblies. Note to make sure the side of the assembly that sticks out most is on the top; this way it won't interfere with the hopper metal below when installing the hopper.

Welding the hinge plates

  • Weld the no-hole plates of the 4 plate-hinge-plate assemblies to the sides of the front and rear hopper plates.
