I would like to build a large witch stirring a large cauldron this year. I haven't had any luck locating a large cauldron (3' x 3'), so I was thinking of making one.
My first thought was to carve a cauldron out of foam, seal it, and then cover it in fiber glass. Sanding a foam block that size would be very messy and time consuming! I was thinking that since the cauldron can be described as a surface of revolution, putting the foam on a slowly rotating base would speed things up, and using a hot nichrome wire would allow me to convert the block of foam into a cylinder, but even going from a large cylinder to a cauldron would still take quite a bit of time.
Any other suggestions?
