You could also call it Megaman, or Iron Man or Metroid, or even those stupid things from Yu-Gi-Oh season 1. However you want to spin it, this is really fun to create and use.

First, you have to know how a Hornet works. The tanks use a back pressure system to fire. Don’t know what that is? Here’s a crude diagram.

Posted Image

Ok, so we need three things: a back pressure tank, a pump, and a release valve. Any subsequent tanks can be wired in series, so they all fill at the same rate and will be released at (roughly) the same time. This is exactly what the Hornet’s stock kill-all trigger does.

The grand diagram would look like this:

Posted Image

Plus or minus, depending on how many barrels you can fit.

So, here’s what you need:

Hornet
A cloth glove
One 3” PVC coupler
Some 1” thick foam
3/16” tees
One 3/16” elbow
One 3/16” barb to ¼” male thread
One air blow gun (can be found at WalMart or Ace, usually with car supplies)
About 5’ of 3/16” tubing
Zip ties

For fun:
12 Volt battery
A few LEDs
Spray paint

First, you have to get the coupler sized right. It needs to fit your wrist tight, but you still have to be able to slip it off your hand. For mine, I cut down 1” thick foam into a 4” by 3” rectangle, and cut the rectangle in half so it was only ½” thick.

Posted Image

And glued it onto the PVC coupler with zap-a-gap. You could probably use high strength super glue or even hot glue.

Posted Image

Now that you know the size you have to work with, prep the Hornet.

Cut the tubing to the Hornet barrels, leaving as much of the tubing attached to the barrels as possible. Cut the barrels apart from each other, so you’re left with something like this:

Posted Image

Using a screw driver, take off the barrel and gray shield, by prying it off. (thanks to Just Some Bob and deadshooter711 for the advise).

Posted Image

The barrel will pop off and leave you with just the tank.

Posted Image

Cut some CPVC and glue them to the tanks. 4 inches seems best. I put some hot glue in the base to set them and level them, then sealed around the crease with plumbers goop.

Posted Image

While those dry, move on to the pump. Seal of OP valve

Posted Image

And if it fits, glue the pump on the inside of the coupler. Dremel as necessary. If not, just glue it on the outside. Lucky me, I have small hands.

Posted Image

Posted Image

Once that is FIRMLY in place and whatever glue you used is dry, move on to the glove. Mark it at a comfortable position and drill holes to literally stitch it to the PVC.

Posted Image

(Also, that’s a battery case under the string, which I’m going to use to power LEDs). One last piece. Take the air gun and use some gas (yellow) tape to seal on the brass barb.

Posted Image

This is also where I put the momentary switch for the LEDs.

NOTE: these air guns seem to have an air leak defect. I tried two of them, and they both leaked in the same area, right out of the hex nut where the seal is held. I was able to fix both of them by using JB Weld and sealing around the nut.

Posted Image

Anyway, the final step is the hardest. Space out your Hornet barrels and mark where you want them. Drill holes to hold the tanks down with zip ties. Make sure the tubing is flexible enough to properly fit them together.

Posted Image

Posted Image

Now for LEDs!

Posted Image

And there you have it. A semi-home-made wrist blaster that can get ~70 with 3 darts on ~6 pumps. And it looks freaking awesome.

The only regret I have on mine is not straightening the tubing. I thought I was going to have 5 barrels, so I didn’t know that last tank WAS the last tank, thus the tubing doesn’t “end” properly and curves upwards to reach the tee. Otherwise, proof of concept and I’m overall really happy with this. :)

That is fucking awesome.

Just a few Questions:

1:Is it comfy to wear?
2:Is it small enough that I could have it on my wrist and hold another gun in that hand?

Other than that it looks awesome and I might have to make one! :)

1) For me, yes. But it's all in getting the sizing right. What's comfy for me might be too tight for someone else.
2) It depends on how you rig the trigger. My trigger is tethered at both ends (one end by the tubing, the other by the LED wires), so I cant let the trigger hang so as to grip a second gun. That said, I can prime a gun in my right hand just fine.

That is awesome. I finally know what to do with my hornet. Do you think this would work with the Tetra Strike?

You clearly don't know how the Tetra works. No, this design will not work with any dump valve tank.

I think, instead of a glove, the next edition should be based around a foul-mouthed sock puppet named George. Wouldn't that be great? You could run around, blast people and insult everyone out of the side of your mouth simultaneously!

But, seriously, this is really fun. I love the firing mechanism, and all the tubes snaking around the entire thing, don't worry about them being straight. It makes it more... frankensteiny. Plus, it doesn't hinder mobility at all, and I'm all about that in Nerfing. Now all that needs to be worked on is reload speed... Mini hoppers? ;) Good job, man.

The mod is solid but I have to say I have seen like eight topics on backpressure works and your's is the first to make any sense to me and it makes TOTAL sense. So thank you for the stellar crude drawing.

And I'm totally on board with the rude sock puppet or perhaps a Triumph the Dog puppet.

-Blasters shoot darts that tag people

I do not play with guns.

I have to second pretty much all of this. I have two hornets just sitting around because I never quite got how they work.
Also a Triumph the Dog puppet sounds like a great idea, assuming the wearer plays the character right.

Was there any paticular reason you only used 3 tanks?

Now you know.
And knowing is half the battle ;)

Dont know why, but I thought of Mr. Hat when this topic was brought up...

That was all I could really fit on the PVC without destroying the aesthetics. My original plan was to use all 6 all the way around the PVC, but that simply wasnt going to work as they barrels would have been blocked by my hand at several places.

That is excellent use of one of those "air blowguns". I've had one sitting around for several months with no purpose. We've also been thinking of making an Iron Man style wrist blaster for Stark and this has given me ideas. Well done.

Blowguns are not intended to be used that way. They will seal normally if you use the 1/4" NPT port as the inlet, and the 1/8" NPT port as the outlet.

I've had the exact same problem when I used a blowgun trigger on an air cannon, and flipping the blowgun around solved it.
