Guys, i need to know some alternative of drain pipe as a PC, i have no idea what to buy, bigger copper pipe is too expensive, pvc is too big, plastic too weak, MDPE possible but is bendy, i need a solution...

2 litre pop bottle. Make sure it's one that was sold containing a fizzy drink, not a still one. Also "branded" drinks (ie coca cola, pepsi) tend to come in more robust bottles than cheaper drinks.
Go easy with the pressure, don't pump too much, and be careful because your safety margin is smaller than with PVC.

thats ok but i cant really attach the bottle to the pipe, i tried a threaded 22mm adaptor, but they dont fit, so i drilled a hole in the cap and attached it, but of course with pressure it flies off

You can use a hose clamp like I did on my APH. Is the inner diameter of the bottleneck bigger then the outer diameter of the pipe? If it is, then you can use a hose clamp, but if it's the other way around, then you could maybe try epoxy? I don't know, wait until someone else offers their solution, because I can't think of one at the moment.

im not really sure...see i drilled the bottle cap to fit, its a tight fit, but it comes out easily under pressure
see the pictures of the gun on the first page, that should explain things

Sorry, I forgot I'd posted on the matter before.

Were you not able to try my previous suggestion. The internal diameter of a pop bottle is almost exactly 22mm, which is the outside diameter of 22mm copper pipe. It should be possible to slide the pipe into the bottle and glue, bearing in mind you can file the pipe down a bit if needed. The cap is not needed at all.

Ok, i got it working, by filling the space between the cap and the pipe with balloons by knotting them around the pipe, so when the bottle is screwed on they compress, and when pressure builds they press on the pipe. it is so effective that at full pressure the bottle doesnt move!
i havent tested it outside yet but, when i riot blast, i get kick back and fog comes out of the pipe after the shot...spooky! with the close to 3/8 nozzle i get a shot time of 4 secs before dropping off. the pic is hard to see but there is a rubber band. i have the parts to make the second pc, just need to get some pipe off my friend, i will soon post shot stats and a video of the spooky fog...lol its probably the contrast of hot to cold

I'm glad you got it to work. Don't forget to post stats and shot pics!

3/8 is about 9.5 mm. 5.5 mm is about 1/5 inch.

I got to test it today, i couldnt get pics but i drew a scale from 0-50ft (10 ft) intervals

3.5mm Nozzle: 42ft/12.8m 5 second shot time
7mm Nozzle: 25ft/7.68m 2to3 second shot time
Riot Blast: 32ft/9.75 <1 second shot time

Pics will come soon

Im pretty impressed with the results, its an improvement of 10 ft on the best nozzle but i think with a second or third pc would seriously increace range as i could use a bigger nozzle...thicker stream...drag less effective...more range...more shot time :) in the end i want this aph to hit 50-60 ft any advise to increace range?

A nozzle laminator wouldnt help as im using a small nozzle, it would just decreace range as energy is lost. but for a better pc, i cant really get anything that i know of, so this is the best and only way known to me.

Are you using drilled endcaps for your nozzles? Because you're lucky to have reached 40 feet, mine only got around 30 feet on the biggest nozzle, and I have 2 PC's! Drilled endcaps are not really the best choice.

But when I improved the nozzle, it now shoots up to around 50 feet. Now, there are several alternatives:

1: You could use a homemade nozzle laminator, I don't think they've ever been made out of copper before, but I'm pretty sure it can be done.

2: You could use a metal pipe nipple, I think that's what a lot of people use. I believe you'd have to get an adapter for it though.

3: You could use my method. You'll need something called an eyelet (Not sure if that's how you spell it or not.), which are found in most hardware stores I think. Once you have one, all you have to do, is drill out the hole on the endcap that's the exact same size as the eyelet, then push it through, (You may have to glue it if it slides to easily.) and voila! You have a good nozzle.

An extra PC might help, but it looks like it's too late for you to add one.

A 7mm nozzle is right in the range for a laminator I think. It's only on the really small nozzles, like 1 or 2 mm, that won't benefit from one.
