Parts list (you can get all of this from your local hardware store). I was able to get ALMOST everything for about $50.
1.) A solid wood base (Mine is 1in thick and 18in across)
2.) Spray paint (if you want to color your base)
3.) Appropriate sized screws
4.) Steel Pipe (Mine is 3/4in thick and 30in tall)
5.) The appropriate sized Floor Flange (Mine is made for the 3/4in pipe)
6.) PVC Pipe (It needs to be wider than your steel pipe, Mine is 1 1/2in wide and 2 feet tall. It doesn't matter that its a little bit shorter than my steel pipe because I will be cutting it and stacking the cake between the layers of PVC.
7.) A cutting device for the PVC pipe. I bought a mini hacksaw.
8.) Wooden plates or cake plates to support each tier. In this case I will need a 12in, 10in, 8in, 6in and 4in plate. You will need to drill holes into each plate that are the same width as your steel pole. They HAVE to be smaller than the width of your PVC pipe.
1.) Step one: Spray paint your base whatever color you desire. In this case my customer wanted a black base. Do not worry about whether or not it is food safe, because your cake will not be sitting directly on the base. Let dry.
3.) Step three: Once the flange is secured, go ahead and screw your Steel pipe into the floor flange. The pipe will come into contact with your cake. I scrubbed mine down really good with dish soap and wrapped it very tightly in saran wrap.
4.) Step four: You will be cutting your first piece of PVC pipe with the hacksaw. You can cut whatever height necessary for the look you are going for. I am only making my first piece about 2in tall. You want to cut only a slight angle
*****If you're not able to get PVC pipe and steel pipe that are close to the same width, than you may have a big space like this between the two. I packed the space full of saran wrap to make it more sturdy.
5.) Step five: You will now be taking your bottom tier that should be stacked on a wooden or plastic cake plate with a hole drilled in the middle and sliding it down the steel pipe to rest on top of the piece of PVC you just cut.
6.) Step six: You will be cutting your next piece of PVC pipe and again, you may cut it to whatever height you desire, I'm cutting mine at about 5in. The bottom of this piece will be angled from the previous cut that we made, and I will be cutting another 45 degree angle at the top of this piece. This newly cut piece of PVC will slid down the steel pipe and should fit like a puzzle into the piece that was placed earlier (you will have to shove this piece through the top of your bottom tier in order to get it to fit into the other piece of PVC like a puzzle.
.) Keep repeating steps 4-7 until you are finished. You can use this method for any sized topsy turvy cake. I just happen to be making a 5 tier! Do not worry about your pieces twisting and turning. It just doesn't happen!!
