UPDATE: 07/30/2007
It's been very difficult to get the cone shape without a lathe, and without putting a layer of fiberglass to the flat part first (that I could find something to secure to) it's been tough going.
If you can learn from my mistakes, bless you. I'm just waiting for the weak as caulk adhesive to dry. Had the thing working for a couple of minutes, but the glue not exposed to the outside was not curing inside of the plastic dish.
I know this does not look safe, but it's got to be safer than using the hovercraft engine/fan/hub as a lathe.
