At long last my rocket launcher is done. It started out with a compact light weight piston valve but turned into this. Its designed to shoot nerf rockets but I have not bought the barrel yet. Right now I just borrowed the test barrel from my Golf Ball Gun. Its a 1 1/2 inch barrel
Edit-Valve was destroyed and has to be rebuilt

Valve-2 inch Piston Valve
Chamber- 2 1/2 feet of 2 inch pvc
Pilot-1/2 inch ball Valve
Power-shoot a pvc rocket through a piece of Plywood at 40 PSI
Range-Unknown

Future upgrades
Paint
Smaller pilot volume
Nerf Rocket Barrel

Looks really good, can't wait for paint job. I would buy a threaded schrader and take all that half inch out. Then just tap the fill into the front of the valve.

Thats what im planning on doing, just need to order a few rare parts, and I have a video I just need to edit and resize it

Ok i want to see it

well ok, Ill work on it now
Edit- It was terrible quality, Ill retake it later

Looks good so far... It needs paint though. Just make sure everythings done before you paint it...

Yeah, Im thinking flat black fittings and green pipe

That would be cool... I'm talking like DeathByDWV... with the dots and all... I can't wait to see the video... ok...

Need to order paint does plain krylon work or does it have to be fusion

Read the can, if it doesn't you can get plastic adhesion promoter and wipe it down so any paint will stick. 3M makes it.

Ok thanks, Ill see if lowes has it, Im uploading videos as I type

Have you tried a dry fire from further away?
My dry fire video is here.

well, I was really just doing some early testing, I was just testing the bumper,piston,and rather or not air was coming out the barrel, ill post some actual shooting later this week, I need to get the barrel and ammo

Looks good! A couple suggestions...

1.) What kind of bumper do you have behind the piston, and how well does it fit in with that male adapter/bushing combination?

2.) A simple way to cut down on pilot volume (although a shorter piston would probably be required) would be to replace said male adapter/bushing combination with a 2" threaded plug. Make sure it's a pressure rated one (you'll have to look at Ace probably).

3.) Going with the above suggestion, change the pilot valve to a 1/4" Q.E.V. Just drill and tap a 1/4" hole in your plug, thread in the Q.E.V., and add a ball valve and male auto coupling to the Q.E.V.'s pilot. There are more ergonomic ways to do that but I'll leave that to you. With a properly "taped" piston and some grease, a 1/4" Q.E.V. should be plenty to pilot the valve.

4.) In the future, you can "butt up" all of your fittings (talking specifically about the female barrel adapter and tee) by trimming down the length of your bushings slightly and removing the lip at the front. You also could probably use a 2" female adapter for more barrel selection (just use another bushing in the female adapter). See here for what I'm talking about...

Just a few suggestions... none of them really necessary. I agree that this launcher would look better with paint, but that's not really necessary either.

Oh, and you can also tape off your fittings and pipe with masking tape before gluing to reduce primer stains. I usually tape them off around the fitting and pipe, and then use a razor blade and some tape to tape off the lips of fittings, although if you're butting the fitting up, just leave the lips alone (maybe file/sand off any markings or mold marks so they butt up completely).

But sorry for all the rambling, the launcher looks great!

Thanks, the bumpers a spring from the nerf recon cs6 , I also tried a pool noodle but for that to work I need a shorter piston, I'm hoping to upgrade to a sprinkler valve as the pilot, I was going to order the threaded bushing from plumbingsupply.com
