Steampunk Weapon: P.H.R.E.D.D. by Nashoba-Hostina Steampunk Weapon: P.H.R.E.D.D. by Nashoba-Hostina
P.H.R.E.D.D. (Pronounced “Fred.”) Pneumatic Hypergolic Reaction Enigma Disposal Device

Everyone knows that vampires are vulnerable to wooden steaks. But what you may not know is that a wooden bullet is just a teeny, tiny wooden steak. Likewise, salt, a purifying mineral, is able to help dispose of pesky poltergeists, and werewolves are repelled by mistletoe. They’d be so useful as ammunition, however, all of these items would be destroyed by the explosion caused by typical gunpowder.

And that’s where P.H.R.E.D.D. comes in! This gun uses the power of pressurized steam to launch its projectiles, preventing the ignition or melting of more fragile ammunition!

Initially, glycerin is loaded into the backmost tank, while potassium permanganate is poured into the reservoir in the main body of the gun. Meanwhile, the topmost canister is filled with water.

The first pull of the trigger will load a specified amount (as regulated by the component adjustment knobs) of these two chemicals into the water canister, where a hypergolic reaction occurs, resulting in steam. This canister is within a larger one, where the steam collects and pressurizes. When the pressure reaches a certain level, a small door inside moves, allowing the steam to go into the second compression chamber (the rapid depressurization of the first chamber cools it off enough to be safe. However, if the temperature spikes too high, there is a pressure release switch that will vent the steam before the gun overheats) The rushing of steam spins tiny turbines, generating a small electrical charge, enough to cause little lights to turn on, indicating that the weapon is ready to be fired.

When the trigger is pulled the second time, it releases the extremely compressed steam into the barrel, propelling the projectile toward its target, be that projectile a bullet or magic scroll.

Happy Hunting!

This is my first prop gun mod, and yes: this started out life as a super soaker. It’s part of my Steampunk Little Red Riding Hood Cryptozoologist costume (the same one I built the Lycanthrope Case for), but I liked it so much, I wanted to make the gun itself a separate deviation.

Sooooo, Nash....I have a question. Could I possibly, if you aren't using it at the time, borrow this for the steampunk costume I am trying to put together for Halloween? It'd basically be the best prop ever, and I need SOMETHING to compliment the steampunk goggles I got at the Ren Fair. XD Anyhoo, please let me know! (I promise I'll be SUPER DUPER careful with it!)

I'm terribly sorry, hon, but I've broken it and I built the thing... I'm flattered, but I'm afraid that I can't loan it out. (I'm sure your costume will be perfectly awesome without it anyway!)

Aw, sadness. I don't know where to get steampunky stuff, all I have right now are some goggles that are pretty awesome but that won't quite establish the look. Do you still have anymore of those cool little clockwork gears I saw on some of your other stuff that I could may borrow/buy off you, or know where i can get them? That might do the trick. =)

So, first off... check your local halloween store. There are a couple of companies that make steampunk props for Halloween.

That being said, should you find nothing, you can sometimes find gears or clockwork/industrial inspired things in the jewelry or scrapbooking section of craft stores, or by buying cheap, defunct clocks from thrift stores, taking them apart and painting and repurposing them. (That's what I did at first.) You can also find them online.

However, there are plenty of other things to use, depending on what your character will be... Guages are neat, and you can get those by repurposing meat thermometers and such. Other attire, such as a vest, belts with large brass buckles, or a necklace with a 'cameo' style pendant also help with the steampunk look, and boots always help. You can repurpose worn out leather purses as beltbags or carry old tools for an engeneering look. In addition, keep in mind, Steampunk also incorporates the Wild West... a western style toy gun can be useful, though it will likely require a little rub n' buff and distressing.

A trend that I've seen in speampunk attire for women are 'teeny top hats' (or small hats in general), attached to a headband. You may be able to find hats of appropriate size in the dollmaking section of a craft store.

I hope this helps a little.

Thanks for the advice, Nash! Between me and Caleb, we were able to piece together a fairly neat outfit. And I can always go and add stuff to it later. ;D We totally made an arm bracer out of old booth leather and some cool metal pins I bought.

I'm so glad to hear that it all turned out well!

Very Nice for a first time prop. I like the creative back story. Did you have to do research on the Chemistry stuff?

Thank you! And yeah, I had to research that out... I don't know that kind of stuff of of the top of my head.
