The only problem is that they use DWV.

Now if JSR saw the pilot volume on that '10 footer'..

[SpudFarm]

pssssssshhhhhhhhhhhhhhhhhhhh (flooup)

that is one indicator that your pilot volume is about 100 times bigger than maximum

what you mean ??
can you explain ?

The blowgun is the pilot on that 10ft sprinkler valved cannon. The red tube is the pilot line. Now that pilot line holds a large amount of air that the relatively small (and low-ish flow) blowgun has to exhaust. Now because theres sooo much pilot volume, it's not going to exhaust as fast as it would if the pilot volume was smaller. The speed at which the pilot volume can be vented decides how fast the diaphragm in the sprinkler valve will open. The faster you vent the pilot, the faster the valve will open. So, logic dictates that the slower you exhaust the pilot volume then the slower the valve will open. This causes a stuttered flow through the sprinkler valve and this is what you see in the video.

If he were to cut that red tube dow then he would see that the sprinkler valve would open faster and therefore there would be more power.

There's no point in me reiterating the same things as my forum peers have said, so my question is:

Did you actually ask permission to use the various pictures of cannons which I know aren't yours?

Thing is, I don't see any credit given to the copyright of the people who really did build them.

[Killjoy]

Uh am I hallucinating or are those two cannons built out of DWV ABS?

Yeah ragnarok I was wondering the same things about those pictures. It would've been nice if he had at least given credit to them.

My poor weak heart, such media should come with a warning!

Did you bother to read the text? The video was removed by the user, so it's little surprise it doesn't work.
