I was on youtube and saw an inline clip, it looked to have 2 diffrent sizes of petg. I was trying to make one out of 1/2 cpvc and 1/2 pvc, but it didnt work properly. Any suggestions on what i should use?

thanks alot i will try getting some thinwall

I have been playing around with the PETG you can get from Mcmaster, and had some great success in making many Barrel types out of it. The PETG has a 1/16" wall and is telescoping like brass. Since it is so thick I only use two sizes.

Inline Clip Barrel: These barrels work great on turrets so you can add two or three more darts in each barrel. It multiplies the number of shots you have. Take a length of 3/4" PETG (chamber barrel) and measure out enough to fit 2 or 3 of your best darts and add about 2-3 inches. Cut a length of 5/8" (fire barrel) and grind the edges of the inside of the barrel on one end. This will act as a funnel for darts when you point the Inline Clip down. Glue the 5/8" barrel inside the 3/4" barrel and attach to turret or breech system.
Inline clips have two parts to them. The chamber barrel and the fire barrel. In this case the inner diameter of my fire chamber is 1/2" and as you can see my darts have a snug airtight fit. My chamber barrel has a 5/8" inner diameter which allows higher air pressure to push around the dart as it tries to expand in the chamber barrel. Once the expanding air reaches the fire barrel it meets resistance from the dart that is partially in the fire barrel (and making an airtight seal). This causes the air to push the dart through the fire barrel. As you can see the last of the escaping air will cause the rest of the darts in the chamber barrel to move forward into fire position (though it helps to point the whole inline clip down to make sure the next dart is in fire position).

Here is an example of an Inline Clip Barrel firing.




Inline Clip with sliding Fire Barrel: One of the biggest problems with Inline Clips and RSCB's is after you take a couple of shots you now have a ton of dead space in your Chamber Barrel. Well with a simple redesign of my Fire Barrel I am now able to move my barrel to meet the next dart in the Chamber. This makes my last shot the most powerful, and keeps my range more consistent through all my shots.

RSCB with Deadspace Slider: Using a pushrod at the back of my RSCB allows me to push the darts forward and eliminate deadspace. The last dart fired has the most power. The chamber barrel is 15" long and holds 5 full sized nerf darts. I'm using an AT3k for power and as you see it maintains its power curve since there is less deadspace. In times of need you can leave the pushrod in and just use the breech at the front of the barrel to load a single dart, or you can open it up and put many darts in. This barrel will hold 5 Streamlines, 7x 2" stefans, or 10x 1.5" stefans. It can even use an AT2k for an air source.

I use the thick stuff from Mcmasters for my Inlines. They are really stout.

I use regular SCH 40 1/2" PVC and 1/2" CPVC quite successfully - albeit with some sanding.

I usually have to sand and hammer the CPVC until it fits snugly into the SCH 40 PVC. I also carve the dart-receiving end of the CPVC so that darts feed better. Simply take a sharp knife/razor and carve shavings out until you have a nice "cone".

Do these things with the materials you already have and you might be successful. It all depends on your darts and the power source behind them.

Oh yeah, use a 1/2" coupler. This allows you to switch between barrel types/rscbs/inline clips which ease.

This seems to be a good time to ask, because I've been curious; is there any sort of PETG, or clear piping that fits snugly in a CPVC coupler, but is thin enough to allow the darts to fall through?

[princexbuster]

Something that I have found quite sucessful is doing what Fome said but putting a little nub of cpvc inside the end fitting flush with the back of the pvc that goes into a half inch pvc coupler for easy dart loading and swapable clips. But that depends on the single barrel material you want to use. (nested brass or petg vs. cpvc)

Thin wall? but Cpvc works beautify as a clip for nanos

I've heard of some people getting 5/8 PETG from some pet stores.

I've gotten 5/8 PETG from a local fish store. It's a bit too small to fit snugly in a cpvc coupler, though. Only thing is is that the ID is slightly smaller than 9/16", making it not a great material for RSCB's/Inlines (I'm guessing with an inline it'll shotgun, and on an RSCB (actually tried this one) the darts slide through way too slowly).

However, that's just the stuff that my local place sells.
