My Ray Gun From Found Objects





Introduction: My Ray Gun From Found Objects

About: I like taking stuff apart and making random things

This is my interpretation of a ray gun that I made with some parts found at Delaney's Surplus a few years ago.

Step 1: Parts Needed

You will need something with a handle. I found this Type-2E Metco Metallizing Gun.

Then you need something that matches up well at looks like it could shoot some cosmic rays and kill some bad guys. Vacuum tubes always work great for this part. I am using a 5868 United Electron vacuum tube. It is fairly big. Measures in at about 6" tall and 4.5" diameter.

I also have this old screwdriver thingy that could work as a handle but did not have a smaller vacuum tube at the moment. I will save that for another project.

Step 2: Test Fit

Check to make sure the parts fit together and if any sanding or other items will be needed to put together. These fit together perfectly and didn't need any other prep work.

Step 3: Clean the Parts Up, or Not.

The vacuum tube had some information wrote in marker on it. The date it was put in to use and serial number. Using an alcohol pad wipe I was able to remove that stuff.

I like the grungy look of the metallizing gun. So we will leave that alone.

Step 4: Final Assembly

I put a bit of hot glue on the glass nub of the vacuum tube to hold it together.

The total cost for this was around $25 I think. As always your cost may vary depending on how you find the parts and if they are originally in working condition or not. I lucked out on finding these this cheap. Looking at ebay for these items the price could be up to $200 or more.

Nicely done! :-)

I'd stick with calling it a metalilizing gun, that sounds like a Si-Fi / Steampunk weapon already!

Really nice work! I made a similar thing a while back, amazing what you can do with old junk eh?


You should put some wires and a janky looking power module on this thing.

Oh, and you should enter the Heros and Villains contest, too.

Great idea, I need to come up with a character idea though

I think this would be pretty cool as a weapon belonging to the agents from Warehouse 13 or maybe a Buck Rogers style hero.

Warehouse 13 is perfect, or even that episode of Voyager when they did the Black and white episode on the holodeck.S5, Ep12

Wow! an actual "Illudium Q-36 Explosive Space Modulator"

So cool! Mine only goes up to 11, this baby looks like it can go all the way to 23!

Nice transmogrifier gun

Looks fantastic. What's the range on this thing and how many shots?

Have not tested it yet. The flux generator isn't working correctly.

check the quantum oscillator 9 times out of 10 it's been reverse polarized by being inserted upside down ;)

The trouble with quantum oscillators is they are working and not working until you actually look at them. I also don't like how they keep disappearing and reappearing again at random. I've started to use Multiverse branded oscillators instead which are made out of a spacially resonant string. Only problem is they are so small they are really difficult to solder and don't even bother looking for one if you drop it.

I think Martin the Martian had one of these.

looks like you really did luck out with finding the metalizing gun at less than $25......what's your secret? lol
