@DR Where did you get your pipe from? Was it a store or a construction site? I'd still like to give this a try, but without breaking the bank. So far I haven't seen any pipe at any of the construction sites around me but I'm keeping an eye out... I found it in a ditch, 30 feet away from the edge of...

Sitting in the garage, wondering why Llamas with Hats is so damn funny, I had an epiphany: If a pulsejet's cycling draws in fresh air to ingnite the new fuel air charge, then why couldn't we do the same to vent a basic metered-propane combustion launcher?

Dude this thread is like 2 months old, nobody cares anymore. "Dude"... This thread is like 1 month old and I still care!

Content deleted and will look for other topic.

I wish the best to you both and am very sorry, to hear about this. I wonder if your doctor has suggested any treatment in the time being... rather than suffering for another 9 months? A quick Google search, led me to this website: <a href="http://www.appliedozone.com/parasites.html" target="_blank">...

Years ago, when the Spudtech forums were still active, we would always warn potential users against using acetylene as a propellant. I'm not absolutely positive, but it takes only (something in the range of) 1/500th of the static energy you would generate, by walking across a carpet, to ignite the a...

By posting this here, won't you get in trouble in Australia?

Have you ever bothered to think just why it is, that we post comments in an internet forum? Whether it be a new topic, or a simple reply to an existing topic, it somehow matters to us, what other people will think of our opinion.

5/16" Steel Brake Line has (very close to) a 1/4" Inside Diameter. A 1/4" Drill Bit fits snugly, inside of the line. You can pick this up at any major Auto Parts store, such as Checker Auto Parts, for example. They come in many different lengths and are usually less than 5 bucks a piece. Hope this h...

As an alternative, you can use a portable mini-fan, which only requires 2 AA batteries. I find these all the time, at Walmart.
