I need to make Hallibel's Tiburon, and after asking around, I found out that my best bet would be to make it out of styrofoam and fiberglass reinforced plastic.

It's that huge thing she's holding. xD Just three questions.

1) Where would I buy the styrofoam and fiberglass reinforced plastic? I live in Los Angeles, California. I'm okay with buying it online too, I guess, but I'd really like to see some before purchasing it, because I've never worked with styrofoam before, and this was the first time I ever heard about FRP.

2) Is there anything better I can make that weapon out of, or is the styrofoam+FRP combo my best choice?

3) What extra equipment would I need to make that weapon once I buy the styrofoam and FRP? Sandpaper and what else? (Like... what do I use to cut it? =/ I just have scissors and kitchen knives, lol.)

Thank you all for your help! :)

Styrofoam can be bought at any hardware store like home depot, lowes, etc..
Usually they put back of the building, near PINK Insulation.
1.5x48x96 for $15, 1x48x96 for $7.

I don't know where you live in los angeles, prices varies

2) Is there anything better I can make that weapon out of, or is the styrofoam+FRP combo my best choice?

Will it be used for mock combat or just cosplay? if its cosplay use styrofoam and fiberglass. If combat You can use EVA Foam, some movie studios use those to make props, light, but expensive more than styrofoam, not breakable. Or use foam boards.

I've heard of fiberglass reinforced plastic couple times, but never knew what was the difference.

:O Home Depot, got it!

Thank you very, very much! This is a silly question, (my pathetic excuse is that I am a newbie, haha) but what type of glue should I use to make sure the different parts are held together? I have no idea how I can find foam big enough to make that weapon, which is going to be used just for cosplay, so I'm thinking the only choice I have left is to get two boards and cut exactly the same thing, and stick it together.

Also, just... how the hell am I supposed to make that? ._.; Dumb question is dumb, I know. But from all the reference pictures I was able to get (AKA the print screen button + pasting it in MS Paint), it's hollow on the top so that she can hold it, and it thins as you reach the end of the weapon (I don't think the weapon itself is like 10 inches thick and hollow, because... well, you just don't fight with hollow weapons).

I dont know what your budget is. Fiberglass resin cost around 35-45 here in CA. If you cant afford it than use foam boards. They are hard enough.

You can do it this way.

For glue u can use any as long it does melt the foam. Don't use hot glue you will have problem sanding and carving.

The only tool you would really need is sandpaper and a dremel... other than the resin working stuff you woud need like a resperator and gloves...

before you think about the fiberglass method read this: http://405th.com/forums/index.php?showtopic=8604

The styrofoam is building insulation foam you can get at just about any hardware store. They come in a variety of thicknesses. You can buy a gallon of resin for neighborhood of 34-40$ and walmart sells smaller cans of it for 10-12$ (its a lot cheaper to buy in bulk)

The dremel and sandpaper come in handy when its time to smooth the whole thing down... patience! no way around it. There's something called bondo that can be found in the automotive section of any hardware store. You'll need it to smooth out ripples you may get depending on how smoothly the resin went on.

I would suggest looking around on the 405th forums because we use fiberglass and resin all the time. http://www.405th.com/forums

:O Ooh, I'll definitely check that out right now. x3 Thank you very, very much! <3

(If anyone else has any advice on how to build the actual thing, I'd love it if you just dropped me some tips. xD)
