Used to do a lot of this stuff huh. Similar rocket using a 1.5 litre bottle. Would pump up to 120-130 regulary. Good hights achieved, easily 100 meters straight up, probably more, its been a while since I did them. Exactly same hose connector but more ridgid base that was staked into the ground. Had...

Yeah I thought it might have been some sort of Barbiturate.

Do you know if you can get the tranq darts without a licence. Anyone know whats in them?

Man, I once had this old 81 mitsubishi mirage (2 door first gen) that we used to thrash the shit out off. One time we had 5 people in this tiny car going 100kph through a forestry road getting air over the rises, was fucking insane. Raping the tits off it just 2nd gear till revving out (probaBLY aro...

Fuck bro....Just get a propane torch and solder/braze that shit. With the correct flux and filler (think silfos or some other brand name shit) it'll flow into those joints nice and cleanly. Just get both surfaces nice and hot, cant really overheat it with a propane torch. I think, from memory that y...

It's all good bro just get it and see. Ive yet to find a coil that doesn't do something and ive got a shitload of differnt types around.

Bro, I used to make water rockets, those things I shit you not would go to about 180-200 meters. Straight up. Reduced nozzle size and circular fins are the way to go.

I made this test piece in a metalwork class. It is a few pipes welded/brazed together in various ways. The main body is just normal steel pipe, with a seam. The end bits on the wide pipe are just steel plate which has been butt welded, with a mixture of brass brazing and the others just melted steel...

With good batterys it should take around 4 seconds. And thats fully charged, full voltage.

Yeah that car coil looks pretty standard huh, should just be able to connect it up and it should work. The ballast resistor is for when it's in a car and is used to regulate the voltage/current so as not to overload the ignition system, but in this circuit we want the opposite essentially. I have ne...

Bro, use the macro setting on your camera in future.

I did some playing round with these circuits a while back, I wrote a wee how-to on using one to make a spark, it's floating around in the how-to section somewhere.

Just done with an SCR. Simple, safe, reliable.

50mm sparks from one cap.
90mm sparks from same cap with two coils.

Hmm, only 145, I take it up to 180 every time. Yeah I had to improvise with this one, anyway, its gone now in favour of a better rendition which is floating around somewhere.

Hmm, ok things are getting complicated. There seems to be conflicting reports of different sizes. On this web site http://www.teamonslaught.fsnet.co.uk/co2_info.htm, it says that the cylinder thread is 5/8 inch UNF which is Unified National Fine. All the fittings I can get here are BSP, British Stan...

Sweet looking gun.
What kind of quick disconnect fitting is that?
Like, whats it used on, where did you get it. I havn't really seen many like that before.
