Been offered a consignment of large precast lego blocks (1600×800×800) Currently on an industrial yard that is being redeveloped. Can get them at keen money, just wondering has anyone ever tried making a silo clamp out of these? Was thinking mostly for maize so wouldn't think the side pressure would be high , or at least not as high as wet grass against them. At 3 blocks high that would leave a wall at 2.4m high. Anyone ever tried/seen it done before?
