storing planes is easy with some shelf standards( the adjustable type) they come in several lengths, and some shelf brackets, foam pipe insulation works for padding the brackets, it makes for a fully adjustable plane rack I have a couple of smaller ones over my work area the 4" size, but the standards come in 4-6-8' sizes.

you can buy them at any home improvement store, Home Depot, Lowes, Wally World etc...
