I looked at the pvc that you used. what is the size? I think that i might use that. and will you guys explain to me what Sintra is?
it's easy... my Legacy kit is made from 6mm sintra and PVC Pipe (and glassed cardboard)
the PVC Pipe comes out to 3/8" only 1/8" more than the Sintra.
Only challenge is to apply enough heat for long enough without totally burning the Pipe.
Once it goes "gooey" it shapes as easily any other hot plastic.

let me just say that I fully expect someone punching my chestplate to break a knuckle or two.
