So, we got a great deal, on an unused 2 ton grain bin on Craigslist. These people bought it, built it, but never had it installed. So we bought it. Small enough to get home in our truck, and here it has been sitting for a while now.
So I finally got off my duff and hired some folks to pour a concrete pad for it.
However, most of the people we called just didn't get it. They wanted to pour a 6" pad, reinforced with rebar, and then we could drill some holes, and glue in some studs to hold down the bin's feet.
That would work fine, even for large racks in an industrial shop, or an RV pad or a sidewalk. But this is outside - a glued in stud might pull out over time. And this sucker has to withstand wind - who's to say 6" of concrete isn't just going to peel up out of the ground during a 100 MPH wind gust.
SO I finally found A & E Land Construction - they understood what I was talking about, and yeah it was expensive. But my grain bin isn't going to blow over in the wind. And the bolt isn't going to heave out of the concrete either. These guys put caissons, or feet, under each of the bin's legs that goes over 3 feet deep, all reinforced with rebar.
And the studs sticking up to attach the feet to... those are looped around the rebar, so they won't pull out over time, either. Very cool. Now we just need to get the bin up on the pad, and get it filled with grain!
It'll take a while, but this grain bin will eventually pay for itself. The bonus here is that a) grain is a LOT less expensive if we buy it by the ton, instead of by the 50 lb bag b) I've been hauling 18 of these bags into the barn every week. Great workout, yes, but I am TIRED of hauling feed bags! I'll still have to haul it out to the chickens in buckets, but it will come to ME first.
