Looking for some advice. I've done a Rapunzel cake before (the tower being the cake), but this time I'm making just a 2-tier w/the tower sitting on top of the tiers. Now I figured I can make the pole of the tower out of pvc, but how do I go about placing it on the cake? Do I use a very long pole and attach it to the bottom board and then place my 2 tiers through it? Or is there a way for it to safely sit on the top tier somehow? It's my first attempt at using pvc for a cake, and I'm just not sure what the best method would be.
I just made a Rupunzel cake a few weeks ago. It's in my pictures if you care to see it. This cake was going to travel about 50 miles so I made the tower out of PVC and gum paste but I didn't attach it to the cake due to the long drive. I hot glued 4 skewers to the bottom inside part of the PVC, leaving them about 3 inches long. Once the cake got to where it was going, the customer inserted the tower into the cake where I had marked. I actually attached it myself so I could take a picture of it, then wiped off the icing. This left a mark where the customer could place the tower themselves. It seemed pretty sturdy. I think your best bet is to attach it on site. Hope that helped!
If I'm picturing this correctly, I think your PVC tower will be hollow, right? Couldn't you just insert it into the cake like a supersized SPS support pillar? Once it's in the cake, you can "glue" your rocks or whatever to it down to the icing?
Yes the PVC I used was hollow. But it was also pretty thick, not like the thinner walls of regular PVC. I guess you could say it was more "heavy duty". If you are going to use the same as mine, I would be afraid to jam the whole pipe into the cake, for fear of displacing it and maybe causing it to crack. If you are going to use the thinner one, then I think your method may work.
