Hi, I've used variations on the pipe and flange method before. I understand how that secures a tall cake from horizontal slippage. But I can't seem to find a description of how you use it to support multiple floating tiers? With stacked cakes, I use bubble straws between the tiers to support the next tier, regardless of which central support i use, but what if you need to "float" a tier? Particularly for ball-shaped floating tiers, I've managed before with using all-thread (one really long bolt) that screwed into the plywood board, then screwing a nut down onto the all thread at the right place, putting a huge washer over that, and then slipping the ball tier (into which center I have previously inserted a bubble straw so it slides easily with no contact) over the all-thread. This works great for supporting the cake but is awkward to dismantle if you have multiple floating tiers like this, since after removing each upper tier you must unscrew the nut that was holding it up before you can slide the lower tier up and off! Does anyone have a better way to float multiple tiers using the pipe-and-flange system?
