Improved ESLT trigger


Low Profile Stock with supa effeminate cheek cushion


Speed Hole is located on the bottom, and enlarged to 3/8" DIA from 1/4". Before the speed hole was right by your ear and made a loud pang every time it was fired, by having it on the underside, the blaster seems much quieter.

I present a monument to all the sins of the Nerf Internet Community: The reduced-length Danger Zone.

I managed to take off a foot of length from my blaster by putting the handle in front of the slots. It's now only about four and a half feet long with the stock. The bow arms are both four feet long. The blaster should be finished this weekend; I just need to install the clothespin and string it.






It is incredibly heavy.

A couple crappy pictures of my two new AABows, based off of Naturalman7's writeup.

DSC00254 by TheNerfZilla, on Flickr

They both have 1/2 PVC stubs cemented on to 1/2 CPVC, because I didn't feel like countersinking machine screws into PVC, and I wanted to get a nice seal.

DSC00261 by TheNerfZilla, on Flickr

One of them has a messy end cap, but the other one is nice and flush.

DSC00260 by TheNerfZilla, on Flickr

That one also has a hook on the end, to allow for variable amounts of pre-tension. It works fairly well, but it needs improvement.

DSC00255 by TheNerfZilla, on Flickr

They both run off of RSCBs.

DSC00262 by TheNerfZilla, on Flickr

They have 17/32 brass barrels, but they need a little more reaming out.

DSC00263 by TheNerfZilla, on Flickr

DSC00265 by TheNerfZilla, on Flickr

They both run off of a new plunger head prototype that gets 100% percent air seal with almost no work. There will be a new thread about that soon.

PullSCRT 2.0





The most noticeable change from 1.0, is the curved 3D printed stock. It's cheaper in terms of labor and materials, and is more comfortable than the old version. We've also eliminated the need for square plunger rod material, which is expensive, and less readily available than 1/2" rod. The priming handle is now guided by the newly added bottom stock bar, which is also 1/2" rod.

You can see here how the new priming handle is wedged between the top and bottom of the stock. The bottom rod fits inside the handle and is mounted by the same screw used to mount the handle.



Another small change is the trigger. Instead of having a 1/4" rod for the trigger spring, we used a longer spring and printed a space to keep it aligned.



I also dyed it purple because it looks cool.

Edit:

I forgot to mention these things.



It's an inflatable air pillow to use for winterizing your pool. It's only $26 shipped and is approximately 3' x 15'. We'll see how durable it is at the next war, and what we're going to do about staking it down. Only takes about a minute to inflate and deflate when using a shop vac.

After more than a year and a half of development, war-testing, and re-designing, I've finally completed my design goals with this optimized bullpup springer.

Here's my primary for SPANO and Apoc:



The retractable stock is the newest feature. You may recall my last version that used aluminum rods. This one uses the same marine-grade HDPE as the handle and body clamps, making it lighter, smoother, and just as sturdy. It has 6 positions and keeps the OAL down while maintaining comfort. The full blaster measures 22" with the stock retracted and a tad over 26" in the 6th position.



Here's a close-up of the stock design:



This version, and all future bullpup builds, uses Ryan's printed plunger head. They fit so nicely into the design in place of a skirt seal sandwich that I didn't have to redesign any aspect of the blaster.

It's hard for me to find a fault in this design with the exception of adding a 3d printed priming grip. It is the shortest possible springer profile with 7" of draw, pull-to-prime pump-action, slam-fire, supreme ergonomics, and a sick plunger head with no vacuum loading. All it needs is a paint job and it will probably serve as my permanent primary.

I'm now comfortable to complete the write-up. Continual revisions have made me hesitant to create a thread only to make constant changes without documented testing. Graduation and job searching have taken priority but I've been watching this video for inspiration on completing the build guide. I believe I've made all of the tweaks and improvements necessary to make the blaster easily produceable, reliable, and pretty cheap to build.

In light of Langley's recent thread on blaster names, I deem the name of this blaster to be Gucci Mang. It has its own theme song.

Picture dump of my old projects. Nerf like it's 2012!
Koree got me obsessed with the DoubleRainbow design, and I made too many of them.



Mega Double Rainbows. 2" Plungers. One for me, the other for ChaosPropel. I'll get it to him one of these days.


Then I made a semi-experimental thing with two 1.25" pvc plungers, it works okay.



I also made a Fallopian Mk. II, which I used at DCNF 5. It worked really well, and I also painted it at some point. It's much longer than I expected, but I also fucked up on on the plunger-compression bs. I'll probably whip a shorter one up later this summer.




I bought an impressively shitty +Bow from someone on here and probably should have made a new one for all the work I put into it. The cuts were impressively bad.

Anyway, I made new 1/4" single-piece side plates that are about 2 inches shorter than the original Slug design, new stock plate, wood handle, aluminum plunger tube, magpul grip, sanded and painted, etc. I didn't put clear coat on the side plates because I kinda want them worn or whatever. I also bolted random metal parts to it., including a Coca-Cola bottleopener. I need to add more.

About 100 hours of work total.

No, you can't have one. This one is for Psyk, and was commissioned 3 years ago as of tomorrow.

Dropbox link to all the parts if you happen to have access to a waterjet, sheet metal equipment, powder coating stuff, a lathe, a mill, a CNC router, a 3D printer, and you happen to be really, really masochistic because they're kind of a lot of work.

I wouldn't expect anyone who can't figure out how to make it based on the CAD models to have access to the tools necessary to build one from scratch. I won't be selling kits or parts for these unless you throw a LOT of money my way.

The hoppered blowgun on top is awesome, and has ample ammo storage with a spare clip and a quick-reload tube. The 6-spot, manually indexed shotgun revolver thing on the main P-scrt output looks super cool, fires well, and points in a varied and completely different direction than the blaster, making it useless in practice. I took the revolver off after these pictures were taken.

The PullSCT that this was built on was originally modified (and mostly built) by Ryan with a manual revolver for demolisher rockets, but he abandoned the project, since those are too expensive and don't really work with our barrels after use with an actual demolisher. I tried to salvage it by turning it into a shotgun revolver and adding the blowgun.

Video on youtube of the Plusblow 5 and Plusblow 5N

The Plusblow 5 and Plusblow 5N, pictured next to each other:

The Plusblow 5 fires Buzzbee suction darts, and the Plusblow 5N fires Nerf elite darts and streamlines. Obviously, the Plusblow 5 shoots farther and more accurately, but most people have more elite/streamline darts so I try to accommodate.

The mouthpiece on the 5N turned out much better thanks to dry filament:


edit: Thingiverse pages for Plusblow 5 and Plusblow 5N

I also did a video showing an easy-to-build hoppered HAMP firing both marshmallows and silicone dome darts.

Prepped and ready for Apoc:


I started this project with the hope of creating a mostly 3D printed pump-action primary. I was mainly looking for two things: easy to manufacture and to hit the century mark and this blaster does both, though it definitely has room for improvement. This blaster is essentially a SCRT design modified for pump-action.

Facts about this blaster:
All of the internal parts and mechanisms are 3D printed. Total print time for all the parts is ~27 hours.

NerfoMania and I assembled the blaster in about 4 and a half hours, which included all the body measurements and cuts as well as two plunger rod iterations. I'm reasonably sure that with some practice the blaster could be assembled in around 3 hours.

The blaster is 25.5" long. It's comfortable to hold as is; that being said, there is a lot of waste in the SCRT design. The front bushing is almost twice as long as it needs to be, the plunger head is larger than it really needs to be, and the handle is about 1/2" too long both above and below the trigger. The front halfpipe is completely unnecessary and the back end could be shaved down slightly. If I so chose, the second iteration could probably be under 2' long.



I originally started with a [k25], but the spring's performance was slightly disappointing range-wise. I upgraded to a [k26] with no trouble fit-wise, although it caused some mostly superficial wear to the first plunger head. I modified the design and printed it at 100% fill, and if it continues to give me issues, I'll print it in a carbon fiber composite I got in. The [k26] is almost full compression and got me to the century mark before the front seal was finalized.



I may have misread the diagrams, but I believe that the original SCRT design had the front bushing entirely mechanically fastened. This would have made the blaster magnitudes easier to service, but I had a small leak in my setup; not enough to be non-functional, but enough to impact ranges and bother me. I gooped the front bushing in tonight, which should improve the seal to acceptable levels. I also removed one of the two O-rings in the front, which I felt was no longer necessary.


Overall, I am impressed with how the blaster came out, and I'm excited to put it through its paces at Apoc.

[KaneTheMediocre]

I just arrived in Spokane on Saturday, and I made my first hardware store run. Since I found some Rival balls on Sunday, I thought making a hopper for them would be a nice and easy first project.
I don't have access to most of my tools, and I don't have a place to work, so I just did this in the parking lot at Ace with what I could find there.







It works, but the performance is not great. I don't have a stock blaster for comparison, but I'm betting the farthest shots (which went ~20m) have about the same power as the stock blasters, and some of them only travelled about half that distance. I think much of the inconsistency has to do with there being too much room for the ball, so it doesn't consistently seat in the same place, let alone against the barrel.

The magazine is 1" PVC conduit, and could stand to have a smaller ID to reduce deadspace and better locate the balls. The barrel is 3/4" EMT conduit, and seems to have a tight but not absurdly tight fit, however since it's such a pain to cut, I couldn't really experiment to optimize barrel length. Duct tape was used to make it fit in the 3/4" PVC T fitting that I used, and the back of the T was cut so that the 1/2" to 3/4" bushing would press all the way into the stop of the fitting to reduce the amount of space for the ball to mislocate. I'm curious to see what other people are doing for Rival hoppers, for some reason no one has posted anything that I've seen. There's certainly room for optimization, and 3/4" thinwall PVC might be better for the barrel (or even the magazine, I'm not sure how it would fit as they didn't have the stuff here and I didn't bring any).

[Langley]

Forgot to post these photos from before Apoc. Stripped the stickers and craft foam off the stock, sanded it, and added some oak trim to the butt to make it a little more comfortable. Rubbed the wood with linseed oil to protect it. Re-wrapped the pump handle with paracord.

The prettier this thing gets, the worse it shoots. I think at some point I made a change to the fasteners on the plunger head that fucked up the seal, because I've been going through washers faster and faster. I might try to stick a skirt seal on it, just because I've sunk so much time into it already.

New rainbow.



Great seal, just some excess friction from the catch. Only around 200 fps, should be able to increase that with some filing and sanding of the catch and support plates, but nothing is certain.

Handle for my next rainbow, it is rather unique so I thought it deserved posting.



Polycarbonate is flush with the wood for optimal smoothness on the handle, i.e. no plates sticking out into my hand. The plates also make for the installation of a 1/4 inch wide trigger easier, eliminating the need for spacers.
