Step 6: Barrel

cut out three rings for the barrel end.

first ring is a larger thicker ring for the rear of the barrel. chamfer one side to the thickness of the second ring.  (see photos)
the second and third rings are the same size but the third is chamfered to the front of the barrel.

paint and fill to make them smooth and space them evenly on the extended barrel (smaller tube inside larger barrel)

then paint the whole lot with black spray paint. i used matt but it can be gloss.
c'est génial ! tu as fait un magnifique travail, je suis impressionnée.

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.
Just need to strong enough to put a potato with an Led on the spokes
I do plan on making a glados potato but it's on the back burner for now.
