Okay, After doing alot of reasearch... wathing hours of videos... i came to a conclusion on how i will mold my helmet.
I just want to check if my plan would work out and if i need to change anything...
I think my technique should be just about right, and could be used by others.
My plan: (after finishing my mold)
Silicone detail.
-Mix silicone rubber, apply thin layer of silicone with a brush for detail.
-add 4-6 layers more with a brush (letting each layer cure until it's "tacky").
-Create keyes (parting lines) using thickened silicone.
-add layer(s) of silicone.
-Let silicone fully cure.
Mother mold. (2 parts)
-Create a ridge using clay to seperate 2 parts
-apply release agent. (any suggestions please?)
-Add plaster bandages to the 1st side of the mold.
-Let plaster fully dry.
-Take off clay.
-add release agent (cant find vaseline... any ideas?)
-Add plaster bandages to 2nd side.
-let it fully dry
-use a chisel and a hammer to seperate 2 part plaster mold from each other.
Preparing for casting.
-Pull mother mold from silicone.
-cut a line trough the "keye" areas, to "open" the silicone mold.
-Pull original model from the silicone.
-"insert" the silicone mold into the mother mold.
-Mix small amount of polyurethene resin.
-Pour it in to the silicone mold and slush it around.
-Repeat previous step as many times as necessary.
-wait for it to fully cure.
-Pry open your mother mold and silicone mold.
-Take your cast helmet.
Party.
-You finished your helmet cast! It's time to celebrate your hard work!!!!!! Yay!!!
I just want to check if this is right. If it is... I'm happy if others use it too
-Finish
EDIT: i will add pics and videos as i get working on this.
