Campbell corrugated

I used Campbell corrugated material for my elevator.  Start with an appropriate size, say 4' x 8', and bend it around something with a smaller radius than your silo. It will spring back slightly.  I used a Floquil paint bottle.  Next time I'll use a contact cement, the ends are starting to lift a bit.

A form?

What if you glued it on a round form like plastic pipe or even a wood dowel rod?

The plastic pipe comes in various sizes and would be hollow.

I like what you did - especially the UP 2010 (looks nearly like my UP 640 - a U-25B).

About your construction - I believe, prototypically, the corrugated sheeting would have been attached 90 degrees from what you have done - moisture would have drained better in that direction. The natural flexing would have made the edge lifting less of a problem. Bending across the corrugations would be stiff.

Grain Bin

The grain bins in the photo are correct as far as the orientation of the metal.

On the real thing they are end staggered and attached to each previous row with approx. 3/4 inch hex head screws and sealed with gray RTV around the edges.

I had the personal pleasure of helping assemble 2 of them when I was in my teens with my brother and my dad.

Thanks, Doug

"I stand corrected". Happy to hear that my presumption was wrong. Always "more than one way to skin a cat".

Arched corrugated metal sheets

Grains bins are a purpose made product. They are manufactured as a package. The sheets are rollformed and then arched to a specific radius according to the size of the bin. Some machines form and arch in one go. Back in the day we rollformed and arched corrugated sheets that were not for grain bins.

 Rollformed sheets come in various profiles and corrugated is only one but probably the oldest.

Can anyone explain how to scratch build the top of the bins?

Grain Bins from the 60s?

Are grain bins of this type also suitable to use on an early 60s era layout?  If not, what would the differences be from these bins?

I don't post often as I consider my writing skills poor. This information is only accurate as my 65 year old memory allows.

I believe the round bin of either corrugated metal or plywood came out of the use of both materials during WWII.

I have seen many of both types I would date back to the late '40s early '50s.

The plywood ones where often wrapped with bailing or barbed wire.

Square or rectangular bins where also quite common.  Built on 16 or 24 inch centres with lapped siding or 1x4 to

1x10 boards, usually rough cut lumber and with guy wire or rod stays

I have also seen many grain bins converted from old homestead houses, machine sheds, chicken coops or what have you. These could also be reinforced with guy wire or rod stays. Farmers where quite practical people.

One could also see grain just piled in a field, perhaps surrounded with square bales or in the modern era with round bales.

I'm sure some internet searching would bring more to light.

Hope this information is useful.
