Yes, I realize I'll have to find a way to reverse the fan, since the current configuration would probably overheat the motor.

Why would it overheat the motor.

So you've tried all these things. How were you attaching them to the valve? The other thing is you mentioned a very small chamber volume. It could simply be that you are using a valve far bigger than you need to which is causing the valve to apparently malfunction. A picture would help enormously.

Just a masonry nail with a little plastic collar.

Reminds me of that coin test we did. The first one I tried was a nail vs a 2p coin. Ended up looking like that with a small gouge in the coin. 2p coins are actually steel, the coins everyone else had been putting nails through were made of vastly softer metal :roll: Use an aluminium sheet, should go...

Wonder what kind of danger pay you get for that lark

What is the hinge meant to attach to and what is being hinged?

I wasn't taking into account those factors merely the problem of expanding the inner section to increase friction.

Watch from 0:30s to 0:45s to see how Canadians tackle :shock: Would if I could. Ok, normally I don't use the metric system (even for length... expressing inches with the decimal system is just as easy) , but I have to agree the US liquid volume units are the most screwed up overcomplicated pile of ...

Cocktail sticks.

Non-permanent and easily adjustable. Available at pretty much anywhere.

100 for 25p @ Tesco for example.

If there's a concern of a stick trying to sneak into the gap then use a liner inside the pipe.

1, very little risk of burns. primitive spud guns have burned me before. +1 http://www.spudfiles.com/forums/viewtopic.php?p=332355&sid=81bf2070203062f2aaf13a23ba8f8ada#332355 - my big post on this page Seriously, what is this I don't even... It's not the responsibility of the cannon to get your han...

If someone can show me that it isn't, according to the rules published on the ATF website, i wont do it anymore. Not the issue though is it. You think you're being harassed unfairly because you don't believe it to be illegal. The fact is you completely failed to read the rules of the forum, one of ...

We've got a Yamaha Grizzly 660, was interesting learning to use it since no one actually knew anything about quad bikes. Idea is to use it for hauling a timber trailer on forest tracks. That and going up and down a ridiculously steep metalled (means topped with crushed stone) access road of maybe 40...

I certainly wouldn't try it on a decent compact camera. A fair bit of what you pay for requires it to still have the lens it came with. Just found a hack for sticking a SLR lens to a phone camera: http://blog.cow.mooh.org/2009/12/phone-o-scope-attaching-slr-lenses-to.html Picture quality seems dubio...

Or you could dump your fly swatter into an ignition coil. I just tried doing that, and it straight up didn't work, I know my coil is good, makes a OK spark off of a 9v, hooked the circuit up to it, transformer just whined, changed a few things around, nothing. put it back to the way it was, nothing...

Yes i know it's for a spark strip for a combustion cannon but, if i'm wiring it up etc. and accidentally jab myself i won't knock myself out. Just making sure before i get any ideas of undertaking this project. People react differently but being knocked unconscious I'd say was... impossible unless ...

If only I was allowed to make a gun for an end project... ლ(ಠ益ಠლ) Did that with my signature cannon. We were given a rather broad brief for our final project so I retrospectively did the paperwork for the cannon and that was allowed. Even did a demonstration firing with potatoes on site, outside on...
