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.
