My biggest gripe with current model ballguns has been with the lack of variety, and somewhat also with the mediocre performance. Every company makes the same blaster now! Look on the shelves, and all you find will be Reactors from Nerf, Cosmic Thrusters from Lanard *snicker*, and Ball Blastzookas from Buzzbee. What happened to the Ballzookas? The Master Blasters? The Pulsators? The most original recent design is the Lanard Ball Blaster, which has an ingenious breech and plunger design. Unfortunately, it uses small balls (1.25" - 1.33"). I plan on replicating it for use with the larger "standard" balls.

But all of the other blasters use the same formula: six or seven round inline clip, inverse push-pull plunger about 2" in diameter. They all perform the same, too. Ranges about thirty feet, and no effective modifications for them. So I decided to change that.

From the beginning of this project, my intent was to convert the inline style clip to an RSCB type. Mostly for simple space savings, but also in preparation for other projects. I began with a Buzzbee Ball Blastzooka, which I had acquired broken at Goodwill for $1. Here she is posing with her friend Stream Machine looking up her skirt.

It was a perfect Jaime Sommers for this project. By the way, in stock form this blaster is less expensive than the Reactor or Cosmic Thruster *snicker*, and holds seven balls instead of six. The original plunger tube had been broken out the back by a somewhat overzealous child.
Posted Image
I started by removing the handles, the broken tube, and the plunger head, as they are unneeded for this project. Then I filled the holes in the back plate, and began reinforcing what will become the new air inlet. I found that a short section of Sch40 2" PVC fit perfectly around. Cut the section and solvent welded it to the tube.

Posted ImagePosted Image
After drilling the air inlet port to 5/8" (mainly because it was the biggest bit I had handy, but also because it fits very nicely), I trimmed the elbow slightly and solvent welded the whole thing together. I also added two extra strips of PVC for extra strength, and then turned my attention to the second part of the project....


The Plunger!

I picked up a Stream Machine water cannon at Goodwill for $2, expressly for this project. Because it's just a simple, huge plunger, with an excellent seal. Just a bonus that it is orange. :)So I started by taking a chisel to the front cap. Turns out it has threads, though, so I could have made it easier on myself. Oops.

Posted ImagePosted Image

These tubes have a nearly identical dimension to Sch40 1.5" PVC, which means that the 1-1/4" to 1/2" reducer bushing fits in nicely with a couple turns of electrical tape. I also trimmed the bushing a little in the back, but that ended up intruding on the open space inside. Easily fixed with some more pipe weld and the addition of some foam padding on the back.

Posted ImagePosted Image

Glue in the bushing, and lastly I added a 1.5" to 2" reducer bushing around the outside to make sure that the inside bushing can't pop out.
Posted Image

And there you go! Load it up with seven balls and start firing!

Posted Image

Oh, but shoot... Pump away and we get the same abysmal range, but twice a many projectiles. Crap. Back to work then.
I had been hoping to be able to keep the sprung follower just for convenience. Unfortunately, it was too much for the air flow, and would push the next ball in to place regardless. The upside is that when we remove the spring and follower, we have enough room for eight balls in the clip! Well, that eliminated the double fire issue, but we still aren't getting full use of the increased plunger volume.
Right! Longer barrel, that's what we forgot! Okay, so we want this blaster to remain compatible with stock Nerf/ERTL/Buzzbee/Lanard balls, so we need to use thinwall 1.5" PVC. Turns out that it is a nearly perfect fit inside the front of the Blastzooka tube. I gently heated the end of the pipe with a heat gun and expanded the outside slightly, just until it fit snugly inside. Then added some pipe weld, and let the whole thing dry until the next day.

Posted Image

Success! The ranges now are consistently 50-60 feet, and we've increased the clip capacity to eight rounds. I will be performing this same modification on a Cosmic Thruster *snicker*, and a Reactor in the near future, at which point I will update this article with any variations.

EDIT: Cosmic Thrusters, in spite of their humorous name, suck. The restrictor ring inside the barrel area is too wide and floppy to operate well with even the green Nerf balls. This whole thing will need to be rebuilt.

Sweet! That looks pretty beast! If it really does shoot 50-60ish feet than that would be seriously fun to play around with! Do you have to push the pump really fast though?

Well of course!

They do tend to be somewhat unruly. But the balls do hit pretty hard through most of the range. The stock balls only weigh about 5g, though, so after a while they will just float.

How powerful do you think it could get if we singled it with a dart rather than a ball?


Gah, REALLY not the point. Beside that, you would need really tight darts and a very long barrel. But push-pull is a terrible method of shooting small projectiles.

Great job, Draconis. You once again prove yourself to be the master of balls. (In the best way possible, of course.) I've been working on something similar using an old green ballzooka and the push-pull pump from an old bicycle pump, but I never thought of making it an RSBC. Thanks for the inspiration.

Well, we're not talking about anything practical really, but people have gotten decent ranges out of a reactor, and this gun is obviously larger, so I was curious as to your thoughts.

First, take out your penis.

Second, open a dresser drawer.

Thirdly, place penis in the opening of the drawer.

Lastly, slam repeatedly.

Well, his had threads... did you try that? If it's acually glued though, since all else has failed you may want to rub some acetone (nail polish remover) or possibly Lighter Fluid on the glued area to solve it.
This is really neat, I have to say. I kind of want to try this with a Cobra Drain blaster, if I read this right... :lol: Either way, fantastic job, I have a newfound respect for balls. *smirk*

I already told you in the IRC, but once again, mad props Drac. I have a bunch of space Reactors lying around with stores already supplying water guns....

I love me my ballguns. Hook up one of these with a FalconStrap and I'll be set.

You just can't look beyond simple capacity for taking in balls can you? I bet the Cosmic Thruster had a much better personality.

Testicle humor? Like any of us would have the balls to try that, with such strict administration.

Anyway, awesome job. I always loved how my Buzzsaw made the balls float across the air and go pretty long distances, but I hated the noise.

So Cal has balls-only rounds on a fairly regular basis, for shits and giggles. This is just plain awesome; I'm gonna have to give that a try. Especially since my work sells those water guns, so I can get them dirt cheap.

How's the accuracy? Some ballguns (mostly the airpowered Bagsified ones) have a tendency to curve one way or the other, depending on some friction on some sides of the barrel. Are you noticing anything like that with yours, or do they track fairly straight?

Do the Buzz Bee brand foam balls work in Nerf ball guns? No stores here sell the green Nerf balls. I have a buzzsaw but no ammo for it.

It depends a LOT on the individual balls. The green balls tend to knuckle ball pretty straight out, but the yellow balls curve a fair amount. This can be mitigated a lot by using very smooth pipe. I find that some brands must use a different process of extrusion, and are rather stippled on the inside. I am also running experiments both on rifling and applying backspin.

Yes, the Buzzbee and ERTL balls work just fine, though the green Nerf balls work the best in Reactors and Cosmic Thrusters. For flywheel blasters like the Buzz/Ripsaw and the Motorized Ballzooka, you can even use the dimpled practice golf balls from Target and Walmart.
