what sort of equipment did you use to make the helix?
we were going to use some emt conduit tubing on our robot and we had a hard time making a regular circle
also I think that loading from the floor through the center of the helix is a very clever idear
We used a central aluminum pipe that holds 60 aluminum rods in the formation of a spiral staircase. It’s a bit heavy, but we can make it with less machining and stuff.
I spent a little bit of time with 469 a day or two before ship, and that hopper is money! Very light, very sturdy, and great capacity. I can see some Industrial Design in this hopper.
