western iowa | I've done 21' and 24' pads for bins using 3/8 plywood. I figure out what diameter I want the pad then figure the distance around. I overlap the plywood and put 3 bolts in each joint with the nuts out for taking them off. I pre-drill the holes before putting it together Put the stakes wherever you want them and put the dirt from the footing on the outside of the plywood to help support it. | |
