Re: [ARSCLIST] LP RECORD STORAGE - plywood/particle board
I'd say that the key to using particle board is to use 3/4" thickness, and to use enough bracing/support that it does not have long spans. I not only screw the end of the shelf to the side/end piece, but also put a piece that is the same height as the shelf the entire width of the shelf (screwed into the end piece) to support the weight on the end, and then put a 3rd piece the same size in the middle of the shelf. As I am using 4' shelves, this means that there are no spans more than just under 2', and these work fine for lps, and do not seem to sag.
I'm not familiar with the regional variations in lumber costs, but where I'm at, good plywood seems to be about 3x as expensive as particle board. Of course, if you have the money to spend on it, good wood is preferable to both plywood & particle board, but I believe that expense was an issue in the original question. I understand this, as I'd rather spend money on music than wood myself...

Awfull Stuff ! Stick To Plywood or good solid - you won't regret it !

I've used chip and particle board successfully in my shelving system. Since
it is either in compression or forced to bend in a complex shape, it seems
quite stable. Few fasteners are used and the dado cut prevents the separator
boards from splitting. However the thickness should be about 50% more than that of
plywood for the same stability and that removes any cost advantage. And it is
very heavy.
Conventional shelving made with particle board in the museum library is a
disaster. It had to be propped up in several ways. It also is sensitive to
moisture and humidity changes causing real problems if the bookcase design requires
tight dimensions. I don't know if the formaldehyde outgassing problems have
been solved, though there is some of that with plywood too.
