i will try to be understandable with my english...
i saw in ace of cakes to stack a cake of five tier with a dowel and a hammer. how does the dowel passing throught the separaiting disks of the five tiers without destroy the cake?
You sharpen the dowel end to a point before pushing it through all the tiers. It will go through the cardboard cake circles, but if you are using a plastic sytem you can't use this method.
Hope this helps!
oh...so they use cardboard...thank you.
