i have been on this forum and many others, and as the geek i am i am very intrigued as to these costumes and mannequins in your custom home theater or game room. and on this handy-man of a trek i found that one of the processes of making such killer costumes is a process called vacuum -forming. now my question is not a matter of how, but a matter of what? i know there are a few plastic that can be used as plausible formers, but all of THESE "alternatives" seem to be out of my [16 year old,] price range. However i found and feel that plastic found in cheap, household things such as buckets and garbage cans, could actually be plausible plastics. I know the average thickness for a forming plastic is .080, but does any one know an example of a plastic that is this ideal thickness? but what im trying to get at is,.... well has anybody tried this, etc. please any thoughts, feeling, or ideas... please post, well, something. maybe you could find a killer tutorial on Google that i may have skipped over. also anyone know how to make the start of a tusken raider helmet?
