im gonna be doing a marine armor set, the helmet is based of a baseball helmet and ive already cut out carboard templates of all the shapes im gonna need to finish the helmet


but i dont know what kinda of plastic to use, i want this to be tough for CBQ combat too.

How do you mold it? ( i know you use heat but how much heat ) what can you use to cut the plastic?

 

[AoBfrost]

Sorry kid, but molding a helmet is expensive, you just dont heat and apply plastic, and you cant use cardboard when working with hot plastic at 450 degrees, molding is not for beginners.

 

[billydakid]

i really dont want to mold an entire helmet

i dont think im even gonna "mold" anything. i guess i can use styrene or sintra and cut out the shapes ill need ( thats what the carboard templates are for ), but i need a little curvature in them

what thickness can i use?

 

[charlie tuna]

You don't have to use vac moulded abs, you can use sintra plastic that's hot water formable and can be cut with anything. To stiffen it you can build it up in layers.

thanks

ill show you what i want to do exatly

i wanna be able to replicate these carboard peices to plastic

so i can use sintra sheets and just cut out the peices, but i dont want boil it, i just need it to curve like that

Fiberglass will still yield one of the best helmets. Just clothe and paint it over, nice work btw.

Good Job!

 

[billydakid]

alright, can you send me a guide on how to fiberglass, costs too

i want this helmet to be tough, its gonna be used for airsoft combat, meaning i dont have to worry about having holes in it or if i hit it agaisnt a wall ( slightly not slamming ) it wont break


also for the body armor, im trying to follow behind link4044's marine armor http://405th.com/forums/index.php?showtopic=876


and on the first page, he did the body armor, it was sintra plastic. so how can i acheive that?

That's where heat forming comes in, either by hot water or heat gun. Just apply heat where you want it to bend

Read the fiberglass sticky, it teaches you to fiberglass.

 

[billydakid]

alright read the stickies


what kinda of plastic and thickness can i use for the armor?

I laughed.

How can you print out plastic sheets from a printer? You cant, you make the armor out of 100lb cardstock, then resin and glass it, if you read, you will understand everything, dont be lazy, read the stickies.

 

[rvb18]

hey aob can he use resin on card bord? that would work if he could

 

[Twitchfmx8811]

why dont u just use spazes idea and go buy a bunch of plastic for sale signs and cut them up.

EDIT: Come to think of it I think it was darth who did it. If so sorry for the confusion.

 

[AoBfrost]

Spase did that for layering ontop the pep piece to smoothen it out, and he bondo'd other areas.
