Ok so dome it’s almost ready , I spend almost 3 days adding bondo , sanding measuring , the with of the flare of the original dome it’s ok , 30 cm, same as spfx dome , same as my gs return of the Jedi cast dome , the main problem it’s the dome probably the original was 4 to 5 cm smaller in al the dome dimentions , put I use allumunium foil paper to gave a base hot glue, and then lots of bondo , the dome on the back it’s 1 cm shorter 13 cm , opossed to spfx , and jedi dome 14 cm each , that’s the only area I am not modify, overall I compare and the dome it’s Now fine almost in proportion , the neck I make it larger using the spfx helmet as ference , then I discover several helmets were using in jedi, and proportions of neck vary in some of them , the reveal helmet indeed have a shortest neck , but not so short as hasbro , mine it’s larger probably fix that latter , anyway se attached images third one original Vader reveal , the others are from Mark Cfo jedi helmet I use the chin triangle to campare with neck distance I know there’s some angle distortion but neck should be shorter than chin triangle, mine it’s 2 cm wider , maybe I’ll fix that, when finish the dome , thanks
