Building a fiberglass Helmet

[T Visor]

This might be a dump question, but has someone tips how to build a completely new helmet from the base of a DP or a Rubies? I mean to create a larger one by cutting the vinyl helmet in two parts with a saw, taking a mold from them, and trying to elongate the left and the right parts in order to build a larger helmet out of fiberglass ...
I’ve flared my DP and my Rubies, but they’re still too small to be screen accurate ...
How can I enlarge a already taken mold? Must I modify the mold before it’s completely dry and how can I do this? Thanks!

I would suggest just starting with a completely new sculpt. You will most likely get much better results by doing that. If you look around the helmet section you will find a thread on how the MLC helmet was sculpted.

agree with krillindb
take the measurements of your helmet
then add just a few milimeters to make more biger
first make blueprints then the sculpt
thats the way
try to scale small things to get experience before expend
to much $$$

You could always just sculpt right over it, just lay on the clay in a uniform thickness right on top of the helmet.

I know i must be a smartass,but I HATE DP buckets..I re-casted an Altmanns..........bigger,better.......1:1.....some I filled in all the battle damage,some i left with the damage.........I have a DP '95,or '96..........I gave it to My 11 yr old boy,Jake.....He prefers My f/glass buckets.............I use it for a doorstop.Damn thing is only useful to show customers the diff. between a DP and mine..lol........

Thanks! I go with Fettcicle's method and will sculpt right over it. Even though I’m a novice in doing that.
