This is how i made my portal gun for halloween 2011.

it is one of many way that you can make a portal gun. i made it this way because my experiances with these materials were higher than any other method. 

Ive entered this to the Hurricane Lasers Contest, if you like it enough could you please vote for me at the top of this page.. Thank you in advance. :D

Step 1: Materials

Blue insulation foam for the main shells of the gun.

the barrel and body were made from PVC pipes at 110mm and 70mm  and one clear 65mm tube. also a solid clear acrylic rod at 20mm

plastic acrylic sheet for detailing parts.

three black cables (thick electrical cable is fine) and wire to put inside.  or three wire core foam wrapping strips (like the hair curling things. i found mind at a general store or DIY store)

for the electronics i had two bright blue LEDs and two red LEDs (shoud be orange but i didnt have any) a three way switch, an assortment of wire and a 9volt battery.

emulsion paint, filler primer spray paint, plastic primer spray paint, lots of white spray paint and black spray paint.

car body filler (most commonly called bondo) i used P38 polyester filler.

Glue! lots of glue ranging from two part epoxie and super glue.

also masking tape.
Wow this is really awesome.i wish i had talent like yours.
That's an interesting response to my work. Please elaborate.
<p>What he means is that this is so stinking awesome and he has no possibility of making one at such high quality so you ,with your impressive skills that he is jealous of, should die. LOLOL :D</p><p>Awesome job. I'm trying to build my own gun with everyday materials and plaster of paris to mold the shells with. Lots of spray paint, superglue, and plastic being used over here.</p>
<p>I personally never played the game but nice job</p>
c'est g&eacute;nial ! tu as fait un magnifique travail, je suis impressionn&eacute;e.
How much money and time dose it take to make this? P.s awesome instruckable!
How many time: Forever How much it is: 299 Dollars 99 cents
<p>im sorry i couldn't tell you how much it cost me to make as i had a lot of the materials in my work-shed already and i scrounged the rest from plumber friends. </p><p>Also i cannot for the life of me remember how long it took to make it, it was over 4 years ago now. </p>
<p>Hey, backwards lamb! Cool prop! Maybe I'll try to make one! :)</p>
<p>do it, give it a go. If you do share a picture so we can see :) </p>
<p>Me again. on a differnt account. i coudnt ;-;</p>
OMG This is awesome. I really want to do this for my halloween costume next year. :)
thanks. if you do make it post photos i would love to see it :)
Hi, Im working on my project now but the only material I can't find is the foam. Is there a specific store I can go to, like home depot or somthing?
I live in the UK so have no idea where you can get it from. But Google is your friend. : <br>https://www.google.co.uk/search?q=blue+styrofoam&amp;client=safari&amp;hl=en-gb&amp;biw=375&amp;bih=559&amp;source=lnms&amp;tbm=shop&amp;sa=X&amp;ei=WOE0Vf32NcirsAH_uIL4Ag&amp;ved=0CAkQ_AUoAg<br><br><br>I got mine from eBay. <br>
This does actully work
<p>Do not look directly into the operational end of the device.</p>
<p>Exactly what I thought haha</p>
<p>have any extra foam left?</p>
<p>If not, what thickness was the foam? Do you think perhaps you could find me a link? Thanks.</p>
<p>or hotglue 2-3 foam boards tougther either way works</p>
<p>well i think the issue is that they cant find the foam. and you cant really use foam board as it has two layers of thin card/paper on either side and you would need a lot of layers. this foam was around 100mm wide, so that would be 20 layers of 5mm foam board or 10 10mm boards not so simple. </p>
<p>sorry i forgot to reply. yes i have foam left but not for you sorry. it costs money im not going to just give it away. but just google Styrofoam or search on ebay. its real easy to find. </p>
<p>can you teach to put it together please!</p>
How thick was the Blue foam you used?
How long should the shells be? Also, how long is the portal gun itself?
Wow<br/>Why pay for neca's is you can do your own.<br/>Congrats!!!!!!!
indeed! also i made this well before the official one from Neca came out.
Hello. Do you mind Telling the Dimensions of the shells?
AWESOME! this is a really good work, I love it
how much would it cost to make if you didn't Have any of the parts already?
i honestly couldn't tell you im afraid. as i did have nearly all the stuff or got it from friends as scrap i dont know how much the parts would cost. sorry
wait sorry, where did you buy the acrylic hook connecters?
Which parts do you mean? The tabs that have a hole through where the front claws connect to with a bolt? If yes, I made them out of acrylic sheet cut out on a laser cutter
How did you make the claws on the front? <br>
They were made from acrylic sheet cut out on a laser cutter.
this is so awesome
Thank you.
How much did this cost you to make?
im affraid i dont know. i made it a year ago and also used lots of things that i already had in stock
i really like the look of the main shells. they look just glossy enough. one question though, how strong is the foam? also, is it very porous like other foams? <br>i have never used insulation foam so if it is easy i just might start.
The foam isn't too porous. It's a very hard dense foam. Closed cell I think is a word used to describe it sometimes. <br> <br>It's a very easy material to work with. You can get good results with it if you spend time on it.
Please can anyone tell me where you got the foam from?
i got this foam from ebay, but model shops and DIY shops have it.
How or where did you get your Logos?
I made them my self. I got the logo from the Internet and traced round it and then cut it out from vinyl sticker sheet.
