Fabrication Steps

  • Plasma cut sheet metal
  • Punch 3/4" holes in all 28 hinges, in center of rounded part
  • Punch holes in hopper sheet metal (all the blue holes, 3/4")
  • Bolt all hinges to sheet metal at the red locations marked "1" with 3/4" bolts
  • Weld bottom hinges of hopper sheet 1 to hopper mount plate
  • Weld top hinges of hopper sheet 1 to grate
  • Install hopper supports to hold hopper sheet 1, and bolt with the 2 bolts (1/2")
  • Weld hinges to hopper supports for sheet 2
  • Weld hinges at base of sheets 2, 3, 4
  • Weld hinges between sheets 3&1, 4&1, and between 2&3, and 2&4
  • At this point, the entire hopper is erected. It remains to weld the remaining hinges to the grate.
  • Upon completing these steps, the 3/4" bolts can be replaced with 1/2" bolts for successive deconstruction and reconstruction of the hopper.
