Following up on the laser idea. What color are her cats? Some Black? Good. BURN! Or.... if you are cheap, make one. Also, for spying, try this. For other anti-neighbor stuff, rotteneggs.com is an ok resource, if you can wade through the crap ideas and flames. ROCK ON!! :P I got a modded 55mW, light...

Nice gun... but a waste of a good beer :P Try and see if a shotgun wad fits inside of the barrel (get em in packs of 500 for a few bucks at gun stores), if it does, drill a hole through the middle of it (lengthwise) then thread a 3" wood screw through it, with the fins facing backward and the tip of...

I just checked through McMaster, couldnt find any springs that work... I know the spring you are talking about, and you are correct, it is too strong (tried using one). Spring are usually pretty iffy when trying to find the right one, different locations have different selections (out here, there is...

Heh, I'd go with Tungsten Carbide myself (Rockwell 79-81 :P ). Yah, wood will do it for you, I've made one myself from wood (if I recall correctly it was made of Oak), and it worked great. I guess you could take a 4x4 and turn it down on a wood lathe to the right diameter, but from there be very car...

You can have the threads cut on a lathe, cheap. BSP is a straight thread, no taper, the only thing that needs to be figured out is the thread pitch and depth of the thread, and if there is enough metal to cut into it while still remaining strong. A machine shop could do this for you at a fairly low ...

Best way to get a BB/pellet that fast is a springer, the really strong ones that shock the air in the piston so quickly its gets really hot, though you wont be using Co2 for something like that. Hell, there is a new gun that shoots 1600 FPS with Raptor pellets (expensive though). You should lower yo...

Uhh, how are you correlating my post with Mr Douche? I posted this for mini spudguns (I'm pretty sure you arent going to find ball valves, regulators, and fittings to make a metered propane system for a mini heh), and I'm not an asshole like Affliction. I'm not sure if many know this, but I was one ...

Meh, kinda what I meant really. Its been a bit since I played with spudguns, so I'm a little rusty in some areas, pardon me.

Jimmy~ Really, all you have to do is give it a couple seconds to run, as long as there is a vent port (the barrel will do as long as its a decent diam, think 3/8+) to eliminate backpressure. If you set the venturi up so that the gases flow around the chamber a bit, say like the port of a vortex BB g...

Jimmy~ You are correct, once you fire you can either blow into the chamber to vent it then inject fuel, or simply inject fuel after firing, but you have to run the venturi for a bit longer. The entire reason I posted this was so you don't have to use a propane torch, they are way to bulky and incove...

Fuel-Injection Method

I recently discovered a great way to fuel minis, I think you guys will like it. You dont have to worry about getting a good fuel mixture, and if you do it right you dont even have to vent the chamber. It uses the Venturi system from a mini-torch, like the ones you find in gas stations (not a regular...

Check the copper pipes on top of your compressor sometime after a long run, should be too hot to touch from the heat of compression. This is the grounds for how two-stage light gas guns work, a primary powder charge slams a piston against a compressed cylinder of hydrogen and a burst disc, the compr...

Thats what I meant, you strip about 3" of wire and wrap it around the middle, then tape the shit out of it, the spark jumps the extremely small gap (only a couple thousanths of an inch). And you are right about soldering, that is one big bitch trying to tin those wires, they dont take solder worth a...

Standard combustions peak at 40-45 PSI, they work so well for accelerating light projectiles because the gas temp is so high (hotter the gas is the lighter it becomes, which means it flows faster than standard-temp air).

Pnuemos are better for smaller heavier projectiles, the higher/longer pressure spike tends to accelerate them much better, Combustions are better for the lighter stuff... And BP sucks btw, its weak compared to some of my recent testings lol, 'cough' steel BB through 4.5" of cedar/4500 fps 'cough' :P...
