wow lot of questions the walls are 3/16" thick and the shafts are 1/2"

bearing and all it ways about 6 lbs. a piece i think

we used set screws this year and that was our biggest problem was them coming loose as well as throwing chains so next year were going to go with roll pins for SURE!! ha

we are also going completely away from chains and using all belts there much simpler!!
