Richard's idea is by far the easiest and most convenient.. use big eye-bolts through the side walls,, use a ratchet strap to winch the sides together,, once you have unloaded that part of the coal bin, and the strap is in the way,, remove it.. there is nothing for it to do if you have unloade the coal in that part of the bin.. Rachet straps are dirt cheap now, just a few bucks for the 1" ones and that is all that is needed.
Well Greg My bin is all screwed together since 1996 and I have Zero Pull outs The screws are drywall & deck 1"-2 1/2 " to 3"
and it is Much easier to had onto the bin to make it bigger down the road with screws in it then Nails And once again your
way Must be be the best way
