Introduction: The Easy to Make a Portal Gun
i have always wanted to make the really cool and detailed projects, unknowing that they require advanced techniques,advanced tools, or lots of money.
in this instructable i will be showing you a step by step tutorial on how to make a portal gun.
Step 1: Materials
the materials you will need are:
- blue wall mart camping pad.
- black spray paint.
- white brush paint.[not shown]
- a toy light saber (the better quality saber the cooler the gun).
- a hot glue gun and hot glue (i advise 2 bags of hot glue because you never want to run out of hot glue).
- a cutting utensil (i used a broken scissor).[not shown]
- a sodding iron
- a picture of the portal gun.[not shown]
- and any other kind of junk u think you can use.
Step 2: Making the Insides
pic (1) using your picture of the portal gun cut two rectangles from the blue wall mart camping pad. one should go halfway from your finger tips to your elbow and it should be able to wrap around your fist comfortably, and the other proportioned to your first rectangle and to your portal picture (this ts the rectangle after the back shell and before the first shell, it holds the light saber tube).
pic (2) glue the first rectangle into a long cylinder rather than a fat one.
pic (3) glue the second rectangle to the first one.
Step 3: Light Saber Installation
pic (1) unscrew your light saber to find out where the LED's are (its a good idea to mark rite below the LED system; remember mark this on the out side of the saber's handle
pic (2) saw your saber's handle at the line you have marked "oh darn" you have probably severed some wires in the processes, but that's why you have a sodding iron
foot note
if your light saber dose not light up or make noise do not worry about steps 1,2,or3just take out the saber part and continue with the project.
pic (3) fit light saber into blue mat piece 2 (its ok if your light saber goes into foam piece 1 ,but only a little) make sure you can still push the sabers button you also must be able to get to the battery compartment in case you run out of juice.
glue
Step 4: The Functional Side
for this step i used some junk i found
pic (1) i used a pill container and i cut off the bottom (make sure the container is big enough for pic 2)
pic(2) fit the pill container over the light saber and blue mat piece 2
glue
Step 5: Shells and Claws
shells come first
pic (1) small front shell
pic (2) large back shell
pic (3) small shell attached to the main body
pic (4) large shell attached to the main body
i do not have a picture of the claws so get creative but attach them according the picture you have
glue
Step 6: Paint It
theres not much to this step besides looking at your picture and painting it accordingly. here are some of my pictures
Step 7: You Are Done
you have now completed The easy to make a portal gun
it glows blue and it makes noise
thank you

I know that you probably did put alot of work into this, and I'm happy if it suits you and you're proud of it, but I don't think that this is of enough quality to post on a site that already has an instructable that looks spot on to the actual gun.

Not everyone wants to make a spot on replica. This is the best *cheap* portal gun tutorial. If you want to make a portal gun for a costume party that may last a couple hours, its not worth it to sink a ton of money and time into a crazy realistic replica. This is what I needed, not one of the other tutorials. Thanks mushroomdude!
