Wooden Storage FORMER CRIBBER REMEMBERS THE DANGER INVOLVED IN BUILDING WOOD ELEVATORS In January 2005, Roger Tonsfeldt, Terre Haute, IN (812-249-9468), wrote an essay on cribbing for The Country Grain Elevator Historical Society’s archives. Tonsfeldt, who cribbed from 1964 to 1969, hopes that the art of cribbing and the men who did such work will not be forgotten. This is the series’ final installment. Wall Settlement LAST IN As a rule of thumb, a A SERIES cribbed wall would settle 1/4 inch for every foot of The runner course spans the length of the structure, while the filler course fills in the gaps. wall height. That meant that a wall 60 feet tall could settle about 15 inches when the bins were filled. To compensate, we would eliminate a course or two of attached to a block and tackle. A pull rope through the V allowed cribbing over the top of a doorjamb leaving a gap to be the two workers to pull themselves up or down slowly—another covered with trim. The trim was nailed to the jamb but reason to start working from the top, as you could climb out the not to the cribbed wall thus allowing the wall to move headhouse window and lower yourself effortlessly. without affecting the door. Sheets of metal were lifted to the installers from the ground, The bucket elevators, manlift rails, ladders, electriwith the help of another block and tackle hung from the eaves near cal conduit, and spouting all had to be secured to allow one end of the swing. Until it was needed, the metal was stored on the cribbed walls to “slip.” a simple rack behind the back rail. The driveway was a separate wood-frame building, which In some areas, metal had to be cut to fit around doorways or did not move at all. It was attached to the cribbed wall with windows. The lead man would yell down something like, “It brackets or cribbed “lookouts” that could slide down the needs to be cut like the state of Utah—cut in nine inches from posts, which supported the high side of the driveway roof. the right side and 11 inches down from the top.” Complicated flashing was used where the driveway The man on the ground used a power saw, with the blade roof met the cribbed wall, to allow for movement while turned backwards. This resulted in one of the loudest, most keeping the rain out. irritating noises in construction. Installing Metal Siding The sheets of galvanized metal had to be cut by the supplier to 30 inches, and each sheet could only have one row of nails. Each row of sheets was lapped over the one below it by a couple of inches and secured with a row of nails a couple of inches above that lap. The bottom of each sheet was held in place by the row of nails and the top by the sheets above it. To install the metal siding, we worked from the top to the bottom, which sounds backwards at first. We stood on a swing stage suspended from the top with rope block and tackles. (This was before OSHA.) This platform consisted of two angle iron L-shaped brackets bolted near the ends of two side-by-side 16-to-20-foot planks for the floor and a couple of other boards that became a back rail. A chain was attached to each end of the angle iron on each end of the platform then pulled upwards into a V to be 142 GJ M/A Adding the Roof Roofing went on after the sidewalls, so the stage swing rigging wouldn’t scratch it. Because the roofs were so steep and high off the ground, working on them was dangerous and challenging. We would take an extension ladder apart into its two single ladders, chain them together at the top, and suspend a ladder down each side of the peak. One man worked from each ladder. Thus, the two men balanced each other. A movement without warning could give your counterpart on the other ladder a major heart attack, so it was important to yell before moving. The ladders were positioned so that two rungs stuck out over the eaves. This allowed the worker to get low enough to nail the bottom end of the sheet, a critical area for possible wind damage. This was particularly difficult, as you had to drive the nails through at least two layers of metal and, at the corners, three layers. I always carried a pair of pliers to hold triple layer nails, as my thumb was usually pretty bruised by then. To get into
