I moved a nice 7 ring bin from a neighbor's farmstead. Hopefully will complete the foundation this week. All of my other bins have the American Conrad metal stands that hold the air floor up. This bin had concrete blocks with 2" by 6" lumber laying on top of them to support the interlocking floor. Concrete blocks are excellent so I am going to reuse them. Tore it down three years ago and now I can't remember the how the concrete blocks and 2" by 6" boards were oriented. Concrete blocks - on their side or with holes up and down??? I remember the 2 by 6's were parallel with the concrete blocks. Typically do the floor pieces lay parallel to the hortizontal under floor unload auger or perpendicular? How far can I space the concrete blocks? How far should each row of blocks and 2 by 6's be? I can look in my other bins for that. Just trying to figure out how the concrete blocks and 2 by 6's are layed out. Thanks.
