I must say, you are a bunch of very creative people. The amount of information I've gathered here in a week, far surpassed my expectations. I joined the forum to find out which Fett helmet to purchase, and after reading (yes used the search option as well, lol) I've decided to construct my own bucket. I have accurate measurements on all aspects of the helmet (decided to use the mystery helmet) except for the "backing plates" behind each of the ears and the depth of the front "teeth". I am already well on the way in construction and will post pics when I get my camera back from the shop. As far as the materials are concerned, I've found it's best to keep with one medium and styrene seems to be working beautifully. I am very anxious for some feedback....when ever that camera repairman gets off his but.
Again, you folks are awesome.
