How to store thin sheet without it warping?

[cpcp]

Hi, does anyone know a solution for storing thin sheet like 3mm particle board and 3mm acrylic so that it won't (or minimally) warps? My problem is that due to space constraints I can't lie it flat and even if I did I would have to sort the sheets from largest to smallest -which would be a big shifting exercise when I wanted the bottom one :~

I have seen some vertical racks in acrylic fabricator shops that used thin dowel but they seem space inefficient. I wonder if there is a solution like the racks they use on glass transport trucks where an arm compresses the sheet stack on a slightly leaning frame?

Anyway I don't want to have to re-invent the Ark if anyone out there knows the best solution.

Thanks for any ideas.

I've kept my thin stuff sandwiched between two sheets of thicker stuff. Keeps the faces of it protected, too.

Right, I find that won't stop the thinner sheets sliding out at their base and pushing the thicker sheets away or have you worked out a way to jam the sandwich together?

Thanks

If you have the sheets upstanding on a timber base, how about something like bench dogs to hold the sheets together.

bench dogs.

That's a good solution -thanks! I am going to make a frame today and I think I will build it on a 5 degree tilt so that the tops of the sheets are encouraged to lean against each other but not so much that they can't easily be separated.

With the bench dogs I will try to add an eccentric cam type lobe to them with rubber outer so that I can get a snug fit with minimal holes drilled.

Thanks for all the help guys :U

My solution was a couple of $2 clamps from the local cheap crap from china store.

Thanks MasterSplinter but I decided that for my purposes as I have sheets from 1200x2400 to 30x30 that the "sandwich" will have to be opened every time I want to eyeball the stock on hand. In a frame it should all be more visible but thanks for the help.
