Okay this may sound really stupid, but from my understanding a cake drum is like a bunch of cardboard cake boards glued together then covered with fani-foil. If i am right.......I thought you can also use Masonite as a cake base, if that's the case why go to the hardware store and get a sheet then you can cut the shape and size you need and then just cover it with the fanci foil or whatever. I only ask cause the craft store is about an hour drive away from me, so it's far and few times I make the trip. If i am totally wrong then please tell me what a cake board is. Thank you.
