The Atomic Splat is the unholy marriage between a Pistol Splat and Atomic Blaster, with an ACE 199 spring thrown in.

Here are two of them - one with a 5-shot hopper (plus one in the wye) and the other with a SorrowX turret.

Tools

- Rotary pipecutter
- Drill
- Hacksaw
- File
- Pliers
- Philips screwdriver
- Mallet or hammer

===

Supplies

- 2 oz (2/3 of a tube) of Epoxy putty
- 1/2" PVC
- 1/2" CPVC
- 1 1/2" PVC coupler or wye
- Plumbers goop
- Super (cyanoacrylic) glue
- Two wood screws should be > 1.5" long and < 3/16" in diameter
- Two pieces of aluminum, 1.25" x 0.5" x 1/16"
- A piece of scrap paper, such as a 3" square Post-It note
- Rubber-safe lube
- Rubber washer
- Metal fender washer
- Electrical tape
- Hopper barrel and magazine, or turret, or breech

===

Prep the Splat Shell

Saw off the Splat in front of the PT bulkhead. File it flat.

File over 1/32" off the two front screw holes on both sides of the Splat shell.

===

Prep the Atomic Blaster Shell

Cut a circle out of the back of the Atomic Blaster large enough for CPVC to pass through.

Leave at least 2mm around the opening. Use the file to remove the orange paint from the flat part of ring.

File over 1/32" off the two rear screw holes on both sides of the Atomic Blaster shell.

Apologies for not including a shot, but the one from the next section should make it pretty clear.

===

Join the Left Shells

Attach the two left side shells using super glue. Hold them together for a minute after applying a few drops. Less is more with super glue.

Align the two metal plates over the screw holes, then super glue them to the shell.

Posted Image


===

Join the Right Shells

Lay the Post-It note or other scrap paper over the joint in the shell

Lay the two right side shells on the other halves, then attach using super glue.

Posted Image


Lay a fillet of epoxy putty between the two right shells.

Let set, then lay a fillet of epoxy putty between the two left shells.

===

Couplerize the Plunger Tube

Drill a hole slightly smaller than 5/8" in the Atomic Blaster's plunger tube. It can be offset if you want to use a hopper, or centered.

Force the CPVC through the hole.

Cut a 1/4" ring of PVC.

Add a drop of super glue to the end of the CPVC that was shoved through the PT, then hammer it into the PVC ring.

Posted Image


(The PT opens to the left).

Apply a ring of Plumbers Goop to the top of the PVC, then pull the CPVC so the PVC ring is against the closed PT end.

---

Cut a 1/2" - 3/4" tube of PVC.

Measure it against the CPVC and cut the CPVC so it is the same height from the face of the PT, or slightly less than the PVC tube.

Posted Image


---

Add a drop of super glue to the cut end of CPVC, then hammer it into the PVC tube using another length of of PVC to transfer the force onto the 1/4" PVC ring at the face of the PT.

Posted Image


Add the coupler or wye to the muzzle of PVC/CPVC.

Add a fillet of epoxy putty around the base. Epoxy putty won't stick to the nylon plunger tube, but it will strengthen it some.

===

Drill out the Reinforcing Plates

Drill divots into the metal plates. This should break the super glue bond. If not, break the plates free.

Using a drill bit larger than the Splat and Atomic Blaster screws, drill holes in the plates once they are free of the blaster shell.

Posted Image


Use pliers to hold the metal plate while drilling.

Here are some after-the-fact measurements

Posted Image


---

Add epoxy putty under the screw holes - this is to permanently attach the metal plates.

Reinforce the spring rest with epoxy putty.

Posted Image


===

Prep the Plunger Head

Hacksaw the Atomic Blaster's plunger head from the tube.

Use pliers to rip off the orange tube.

Use the tip of the file to level off the remaining ring.

If not present, drill a small hole in the intersection of the plunger head.

Posted Image


---

Fill hole with epoxy putty.

Assemble washers and screw.

Drive screw through hole in center of the plunger head. It doesn't matter if the plastic breaks or not.

Pack back of plunger head with epoxy putty.

Pack CPVC 1/2" deep with epoxy putty.

Posted Image


Attach CPVC to plunger head.

Posted Image


Make sure plunger rod is perpendicular to plunger head.

Let set.

===

Prep the Splat Plunger Rod

Remove Splat's skirt seal.

Use pliers to rip off the nub that held the skirt seal.

This should reveal a small hole. If not, drill one.

Drive screw into hole.

Posted Image


Wrap exposed shaft of screw with electrical tape until it is the ID of CPVC.

This allows us to adjust the length of the plunger rod as needed. We can't all get it cut perfectly the first time.

===

Assemble Plunger

Lay plunger rod against the Splat's forward bulkhead.

Lay plunger tube against the Atomic Blaster's forward bulkhead.

Insert plunger and rod until it is furthest forward.

Measure CPVC where it overlaps Splat's original plunger rod.

Posted Image


Cut CPVC to length.

===

Putting It All Together

Posted Image


Wrap the front of the PT with a layer or three of electrical tape to prevent it from freely rotating in the shell.

Most likely, there will be a corner of metal sticking out. File it down.

Lube the PT.

===

If using a hopper, file the front part of the shell so the magazine can fit. You don't need to file down the actual screw post, just the top of the front of the shell to that point. See the upper Atomic Splat for example:

Posted Image


The upper Atomic Splat is actually the first one I built, which is why I don't show the filed-down front shell in the build photos. It had a centered coupler, so my filing down the shell to attach the wye didn't work. Its centered coupler is now in the lower Atomic Splat, whose PT was made with the off-center PVC muzzle to accommodate the wye.

===

Thoughts

- The Ace 199 spring is pretty much a must. The stock silver-and-blue Splat spring isn't well-suited for a 2.2" ID PT.

- Venom213 sells them for $6. Well worth it, if you're going to do this.

- He sells a spring rest for it as well, but I was short sighted and didn't opt to get it. I'll have to use a washer.

- I've had a 10-shot hopper on it. It shoots okay, though there are feed failures. I may add a guide (see BritHop) in the wye to alleviate that.

- The SorrowX Turret gets over 90'.

- The 5" CPVC barrel gets about 75'.

- I'd estimate total cost to be $30 - $15 for the Splat, $5 for the Atomic Blaster, $5 for the spring, and the remaining $5 for the materials and consumables. Note that this does not include the magazine system, only the base blaster.

- It took me about 2 hours to build my second one, including taking measurements and photos.

- The epoxy putty, even J-B Weld, isn't strong enough by itself, especially you're going to hold it by the front handle and prime it.

- The PT face isn't very rigid, so the barrel may flex some.

- It's also not machined with high tolerances, so the barrel may not be straight.

Thoughts / comments / flames / questions?

That is hella innovation. Now I can do somethig with all my damn Cosmic Thrusters I got in packs with Sonic Bazookas :D

So I would assume this could be done to combine any lever blaster and pump ball blaster, like a Pulsator. OR, as a replacement PT and plunger head for any springer really. Way to open new doors of potential.

Much thanks. I think this can be done with any overpowered springer. The hard part is finding a priming mechanism, because even the stock blue-and-silver Splat spring wasn't enough for for the Reactor's PT. I think whatever workable spring (K14?) would need mechanical advantage, such as gearing, pulleys or leverage, such as the Splat.

Hm, the Pulsator gives me an idea. Maybe we can use solenoids and dual hoppers, and get something full-auto / double-barrel out of it.

Then again, I don't like eBlasters. Factory ones are generally a pain to mod, and ones that are augmented such as compressor-airguns seem like cheating. But, that's ultimately up to each Nerfer and war host.

Anyone have a cheap Pulsator for sale? :)

Couldn't you wrap electrical tape around the "plunger tubes" to keep them from wiggling? Or, if that doesn't work, use scraps of FBR with tiny amounts of hot glue?

Edit: I'm dumber than Hell. But could use make a thicker PT face that uses a little more room but keeps itself rigid?

Edit 2: I'm dumberer than Hell. I thought the Plunger Tube was the other way around. I'd go with more electrical tape around the plunger tube itself. Ignore the first edit.

Don't worry about it, MB. The PT is reversed from the way it normally sits in the Atomic Blaster / Reactor.

Now that I think of it, I probably can use a jar lid to reinforce the face of the PT so the coupler / wye is more stable.

I have three layers of e-tape on it, one flat, one deliberately twisted, and a third on e flat. That's enough to keep the PT from rotating. And the one with the wye has the angled intake socket nested in a cutout in the shell, so it's not going anywhere. I'm just looking for a way to keep the barrel from flexing, that's all.

===

Bob - you were idle on IRC, but I left you a PM. At this point, I'm more curious than interested, but a shipped price quote to 98052 would be appreciated.

Wow. This is truly innovative. Lately all the mods done to blasters have been a bit too...similar. But this is amazing.

Much thanks. Someone on the unofficial Nerf FB page asked if I could dual-wield them.

Each shoulder strap is attached to the priming bar. Push blaster forward to prime. Priming bar is also attached to bungee, which returns it to firing position.

I have died and gone to Pistol Splat heaven! Very nice, Taer. Can't wait to see them in person.
