I'm not sure why some people didn't think the ranges possible, considering with similar hardware (modified squirt guns) ranges of 250ft were obtained. I think it's great and all that this has been done with a true nerf gun though.

Nice! I want to know the ranges once you put a barrel on it.

Personally, I'm waiting for the PSP.

What about the bike pumps that use co2 cartridges instead? Those would make for some quick shots.

It's funny that I just see this posted. Only a few days ago I was considering building a flash from an old camera into one of my guns. I figured out how to wire it and all right next to the laser sight. In the end I decided it was sort of pointless and scrapped the idea. It is possible to put a simple disposable camera flash circuit into many guns with a bit of wire and solder though. Just open up a standard disposable camera and you'll see what I mean (careful though, one of those shocked me pretty hard when I touched part of the circuit).

I don't know how to measure psi on this kind of thing. If anyone has advice for some mechanism let me know; until then I'll be thinking about it. Maybe i can use the cap from the 2nd tank I sawed off of the storm2000. hmm

Oh, the light is operated by a 'noid, like on the NF, right?

I don't own a NF, and I'm not sure what a 'noid is. However, I can tell you where the switch is. If you look closely on the innards picture, you'll see where the trigger is connected to something with a bent metal rod. What it's connected to is the mechanism that opens the valve. On the very thing that presses on the valve pin is a rubber-covered switch which closes the circuit to the laser. It works quite well since the valve pin is held by a strong enough spring. So, to turn the laser on, pull the trigger a little, and then fire by pulling all the way.

For about 2 weeks I've been working on gutting an old squirt gun (Storm 2000) out, and over the course of the project, I kept changing the innards more and more. Now that it's complete, I'd consider the inside more than half homemade. It's got an 18 inch aluminum barrel with back loading breach-like design. The barrel sounds long, but the volume of the tank makes sense for it. It's also got a laser in place of where some stupid light used to be on the squirt gun. I used the same battery compartment and the same on/off switch build into the trigger mechanism for the laser, and it works pretty nicely. Originally the barrel was much simpler, and I just shoved darts down. Using that design I got 170 feet flat with only 3/5 of the tank's maximum power (before pressure release kicked in). I'm new, and I'm guessing this has been done countless times before, but I'll post it anyway.


Innards, and a TT for scale


A look down the back of the gun, in case you don't understand how the breach works exactly.


The end stopper I designed. It goes in the back of the loading area and is tightened to create a seal.


This is where the laser was put in (front of gun).

This was heavily influenced by the R.s.c.b. loading system. The gun is basically a homemade fit inside of a squirt gun case for looks (however I did use a lot of the valves and stuff from the squirt gun). As for ranges, I'm going to be gone for a few days, and the epoxy won't be dry before then. Hopefully by posting the ranges I won't just be bringing back a dead topic.


Pretty picture

P.S. Sorry about the typo in the topic name (I'm such an idiot).

Sorry I'm unsure of the origin of this aluminum. I've had about 12 feet of it in my garage for as long as I can remmeber. It's nice because it's so light, so I can add long barrels on without weight issues.

The epoxy worked like a charm. I can pump the tank up 50 pumps with no ill effect! This is not a hornet though, just so you know.

I just wondered if epoxy holds leaks under high pressure, since I'm dealing with a related problem. Would it just sort of break apart when pumped up, or is it strong enough to hold under pressure an air tank usually experiences? I will probably just have to use good old trial and error.

What about aluminum? I've used it on 3 guns now and am working on another with it. I'm not sure the size it was listed as but it fits my 1/2 inch stefans perfectly.

Ok, here is what I've done in the past when I've needed a screwdriver shape that is uncommon (such as a triangle bit), and was too cheap to buy the bit. Get one of those Bic pens, the clear ones which come in 10 packs for 1 dollar at most targets and office supply stores. It has to be the clear kind. Take out the ink part of the pen which can be pulled out by the ballpoint tip (should be golden brown color) with pliers. Check to see if the clear part of the pen fits to where you need to reach the screws. If it does fit, great, but if not then sand it down some so that it fits. Then take a lit candle and heat up the clear part you have left til it starts to soften up. You should be using the end that the ballpoint pen used to be at, not the end with the colored cap. I recommend using a candle holder with the candle so you can press the pen up to it to test if it's soft. While it's still in it's soft state press it onto one of the screws firmly and hold it there for about 10 seconds or so so that the pen takes the shape of the misshapen screw. Hopefully you can twist and the screw will turn. If the pen sort of grips and then just gets scraped because the screw is too tight, reshape it with the candle, but put it in ice water right before attempting to turn so that it is somewhat harder. Repeat this process of shaping the pen for each messed up screw. When putting it back together hold each strange screw with pliers and press the pen to it again when heated, and screw in. Good luck! I hope I'm not too late.

Here's my mod for the Tech Target gun. Three changes occurred:
-Smaller barrel for 1/2 inch (homemade) darts, also slightly longer
-No air restrictor
-Stronger spring

Since I took photos after doing the mod, I'll only have certain views.

This is the gun opened with the (aluminum) barrel already in.

http://tinypic.com/1kbr8
As you can see, the barrel comes apart easily from the main part of the gun.

This is an important part of the barrel. It has to be cut neatly out so that air is allowed through easily, and should line up with the inserted barrel.

If the pictures won't load, it's because I dont have photobucket yet, so the geocities site might be over its limit.

This gun gets a pretty good range; I measured around 65 feet angled based on 3 test fires. I know other people have modded this gun, but I thought some looked kind of sloppy, so I made this one clean looking. The main issue i have with this gun is that it is noisy for being a small plunger-type gun. I can't figure any practical ways to make the noise quieter without reducing range.
