Ends need to be turned down to fit auger pipe.
Auger flighting end bearings and shafts. A length of bronze bearing material was turned to size and press-fit into a short piece of schedule 80 2" pipe that had been bored true on the inside. The steel will be welded to supports on the end of the augers. Short pieces of shaft were turned to size to be press fit into the flighting pipe. The bearing end will rotate in the bronze bushing. Shafts were bored, cross drilled, and fitted with a grease zerk for lubricating the bushing.
The average O.D. of the pipe is 7.991" If I use eight rods to make the cage, that will leave 3" wide slots. The exact spacing was 3.058" O/C. A caliper was used to etch those dimensions near the end of the pipe. I then marked the scratch lines with a permanent marker, slid one of the bands on, tightened it, and marked those lines on the band also. Using the seam where the tubing was joined as a reference, I slid the band up so the rods would extend past the end of the pipe about an inch, turned the band to align it in the same place relative to the seam and tightened it.
Two bands have been cut. 16 rods have been ground flat on one side so they will just clear the pipe when they are welded to the band. The two longer rods will be formed into a ring that is 7.991" O.D.
The rods are aligned with the marks and held in place with short lengths of drapery cord. The end ring has been placed even with the ends of the rods and everything is ready to be welded in place.
One cage has been welded and removed from the pipe and the other is ready to be welded.
The bearing alignment jig will be used to center and align the bronze bearing in the end of the cage.
Short lengths of rod have been cut and are ready to be welded to the bearing and cage end ring.
Pieces cut to shape & size. Need to have a lip bent before they're welded.
The traps have been extended and a small slide makes cleanout between seed varieties less of a project.
