Over the weekend we went over near Akron as my girls father bought two drying grain bins at a farm sale and wanted to take them apart and haul them back. These bins are 30 foot across and about 30 foot to the cap at the top. Made out of curved corrugated panels and held together with about 4000 screws each I would guess. I know we had (2) 5 gallon pails of bolts and nuts when done. The farmer had 3 of them and moved one to join in with his new storage bins by moving it with a crane about 500 yards picking it up and swinging it around and then moving the crane a dozen times. Ours were not so easy. Six of us started Saturday morning at first light and worked till sunset and then drove back the 2 two hours because there was a golf tourney in Akron and no rooms to be found. Got home and slept about 5 hours and headed back. Did I mention I might have stayed and slept in truck but it rained almost the whole weekend and with the mud the thought of a shower and warm bed was worth the drive. These are the only thing I ever worked on where you take them apart from the bottom up and build them from the top down. The pictures will show the jacks we used (3) were rented and we built (4) more out of boat winches and scrap laying around at home. You lift the whole thing and take off one ring at a time, then lower it move the hooks up and do it again. Most of us were past the age that should be thinking of doing this stuff but we got r done. Not looking forward to the puzzle of reassembly. Last photo shows the new bins with me standing in front for scale the bin on the right was the one he moved and the same size as the ones we took down.
