  • 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.
