To be clear, with the proposed climber design that inspired this comment for my team, we were planning on use 1215 steel hex, not aluminum (including Thunderhex). Given that compression of balls in our intake caused deformation in a ~24" piece of Thunderhex last year, I am definitely shying away from Thunderhex and any aluminum shafts as a primary weight bearing piece of our climbing mechanism.
Turning down the corners of the steel to fit into a Thunderhex bearing is a possibility, as is hex broaching a
larger round bushing to fit the hex.
