I made a Pumpbow! It still needs the bracket to keep the pump from going up. But Its finished! Took me a long time to finish it and im happy with it. IT uses a [k25] for an easier prime.

[ChaosPropel]

I've put aside my pumpbow project to work on a Fallopian Mk2....here's what I have done today, which I did over about 3-4 hours of light labor with some breaks and a dinner.

You can see that I have the plunger rod done (except the catch notch, which will come last). This was a real challenge, as in the Fallopian, at least under my measurements (which include 6" draw), there is 13.5" room for a spring. However, the [k25] I'm using is only 11"-that means I need a 1.5" spacer at the front of the plunger rod, behind the head. I used some 1/2" PVC, superglued to the 1/2" delrin plunger rod. However, the [k25] still rode up the PVC, so I made a custom disc out of a PVC endcap (too lazy for polycarb, lol), with a 1/2" hole, and an OD big enough to hold/block the spring, while small enough to still slide in the 1" PVC inner float support. That's the white thing you see. Then there is etape under/to the left of that to stabalize the [k25]/center it.
There's also the rainbow catch I made for it and the SSSB stock I'll be using, similar to Zorn's original build.
I hope to get this finished up tomorrow morning.

[One long shot]

This is the valve I've been working on for the past few weeks. Version 2 will be smaller and much more efficeint. This sucker's made out of 1" PVC and eats an entire breakfast, lunch, and dinner of air in one shot...



There it is in reference to my crossbow. They look oddly alike, don't they?

Needs a handle.

Ambassador and I were doing some thought work in the IRC the other day, this is mostly a proof of concept.
I had the idea of using a Dart Tag Sharpshot catch, handle, and trigger as a replacement for a clothespin trigger on a snap, and he suggested putting a nail through it, and I thought that it wouldn't be strong enough, so I machined this thing out of 1/4" square steel rod.

Something little more exciting...


Made for Roosky of OzNerf. I really like the tinted polycarb a lot.

[the mod man]

Home made HPA powered full auto machine gun. I tried to make it a bit 50.cal esque but I'm not skilled with cardboard, but as taerKitty says "Fugly is a feature". It's essentially a cardboard box with tape and an enormous 45 round arscb. I was a bit worried that due to the magazines length there would be to much dead space for it to work efficiently, but after filling my HPA tank and testing I found it worked well and that a 45 round burst didn't even put a dent in the amount of air in the tank. I tested the range from where I was standing to a wall 50' away. It went straight at the wall and didn't drop till it hit the wall. The rate of fire is adjustabl depending on what preesure it is set at. I testesd it at various pressures to find a rate of fire that wasn't so fast it was just a shotgun spread. I settled on 19-20 rounds per second. I am also working on speedloaders for this. I am planning on replicating it with some polycarbonate from mcmaster. For anyone wanting to make one it would be EXTREMELY easy to replicate, The whole thing took 30 minutes total to make. Overall something fun to use if you want to go crazy. I'll try to get video up soon but I'm out of air in my tank. I may be able to get it filled this week and I'll be sure to put some footage up if I do. PM me if you have any questions. Also once I get the polycarbonate I'll make a writeup if asked.



Trigger.



Carrying handle and sight.


Riot shield just for fun:




Edit: Polycarbonate is here and it's getting cut very soon

I made four Snaps:


From top to bottom, left to right:

Supa shitty snap revolution:
Doesn't always catch, especially when quickly pumped back
~6" of draw
plunger rod made using 3/4" pvc conduit

Short Snap side arm/secondary:
Very smooth trigger pull
~3" of draw
Powered by 2 home depot NF replasement springs (everbuilt springs?)
Snap 1 style handle using 3/4" pvc
uses 9" CPVC speed loader

Supa dupa shitty mini SanchoPanza:
Powered by 2 Ace 49 springs
3-4" draw
uncomfortable wood handle based off a recon handle(uncomfortable because I haven't rounded the edges yet cause I'm lazy)
Too much friction from the plunger head so it cant move forward fast enough(this will be fixed soon)
was originally going to be mounted under the snap bow on the bottom in the picture

Snap bow
superlative plunger head
super comfy recon handle based thumb hole stock/handle thingy (the fugly gap at the end of the handle/stock piece will be filled with epoxy putty when I get some more
super smooth trigger pull
~6" of draw
currently used with a 14" PVC/CPVC slide breech (shown on SanchoPanza)
6 1/4" vent holes next to where the stock is attached on the top (will be doubled to 12 shortly)
powered by 3 Everbuilt NF replacement springs

Built a 2-11 for Shoopy. The wooden handle and stock are actually pretty comfy.


Uses an extension spring instead of a rubber band. Makes the trigger pull a lot better.

For posterity. $$$

I acquired an old set of fly-wheels from a broken Tommy-20 and was challenged with the task of turning them back into a weapon. This is the result so far, it can fire darts around 30 feet however it is a pain to hand feed the darts through the flywheels with your other hand. The goal is to be able to still hold and fire a gun but also have an emergency automatic wrist gun. I'll post a write up once its fully finished.

If anyone has any ideas for a feeding mechanism i'm all ears, thanks.

I finished my plusbow.



I made a wood handle out of oak wood.

[Flaminace2468]

Now before people flame me for using a longshot shell, I got this thing at Goodwill and it was T-O-A-S-T. So I'm NOT insane and I DIDN'T waste a perfectly good longshot. Carry on:

Caliber: 3b arrows, titan missiles, whistlers
ROF: you could make and eat a sandwich and I wouldn't be done loading it.
Max range: (3b arrows)60 ft (titan missile) 80ft (whistlers) 250ft
Effective range: (3b arrows) 50ft (Titan missile) 70ft (whistlers) 150ft
Accurate range: (3b arrows) 40ft (Titan missiles) 60ft (whistlers) 125ft
Intended use: respect with the neighborhood kids yo!
Loading: Load ammo, pump to 60psi with a bike pump, hit electric switch in handle, powered by 2 9v batteries in a hollowed out clip.

My first homemade, EVER!!!: A SNAPbow Mk. V





I love this thing!

[andtheherois]

Just finished up my latest Pumpbow.


things painted black to match. Used Psyk's idea of using the firefly handle on the grip. It's comfortable now! I need to pick up some black UHMW next time to go to MMC to swap out with the white.


Self explanatory.

[fogeater]

a pump snap that has a new stye prime and catch that is more reliable stronger and smaller


smaller plunger head


more info stroke 4 inches
springs lanard shotgun nitefinder and a 2 inch by 3/4 id spring
this give me lots of power
ranges 90s
it ways about 5 or 6 pounds because of the 40 screw i had to put in it

Finished a homemade pulsestrike. Uses about six or seven inches of a [k26] and a 1 in. type 200 pvc plunger tube/tank. Needs a ridiculously long barrel (over two and a half feet!) and achieves ranges of over 150ft.

Also created a french cannon of doom. No practical uses have appeared yet thought. Utilizes a homemade piston valve,a two inch two foot long pvc air tank,and a dual action bike pump that takes fifty pumps to get to twenty psi.

Edit:I've been doing some testing on the power of the cannon.It requires a huge, unwieldy barrel. At less than twenty psi, I shot most of the way through a piece of aluminum sheet metal and dented half inch plywood. Although I was using a dart with a screw jammed in it and wrapped in e-tape, it was still impressive.



Edit 2: I do not even relatively plan on aiming this anywhere near a living organism. I built it for the fun of it and to experiment with piston valves. To even aim it at a person I would have to shotgun it over forty times.

My latest homemade blasters. Starting with a snakerbot Shortened PumpSNAP.



I couldn't find 1.5" Thinwall PVC, so I had to use two 1.25" couplers, sanded out and bolted to a 2" pump slide. The extra PVC makes it slightly heavier, but the extra-wide grip is nice.



I used a Scout grip for the handle. It's mad sloppy because of several different attempts at getting the trigger to catch properly. I don't like using L-brackets as triggers, so I used a scrap piece of 1/4" polycarb. The sliding trigger takes some getting used to, but it works great and I haven't had a misfire yet.



This is my take on the SNAPbow Mk5. The design is great, except for the dependence on hot glue to hold the forgrip onto the body of the blaster. So I sanded out a 1.25" tee that reduces to 1" for the foregrip and solvent welded it all together. It's rock solid now and I never have to worry about it coming off.

Here's a close-up of the CPT



The entire handle and CPT assembly is entirely mechanically fastened, excluding a bit of hot glue to keep the clothespin from wobbling around. There's a 3/8" screw bolting it to the body of the blaster for actual support. I used my leftover +Bow templates or the handle, which is made up of three different pieces of wood that I scrolled out and bolted together.



Here are some components of the SNAPbow pre-assembly. I took the time to ladder sand every piece (80 grit to 600 wet-sanded to finish). The blaster is "soft" to the touch and I really like how smooth the draw is.

I'm not a fan of using a plunger head with an epoxy putty ramp, so I went with the combination plunger head from snakerbot's write-up (or whoever came up with it). I've found that 3/4" PVC endcap ramps give me a much more consistent catch and are easier to fabricate (personal opinion). I use this head in all of my SNAPs and it gives me a great seal every time.

I use a full [k26] that hits almost full compression. I compressed the spring fully inside the blaster and marked on the plunger rod just outside of the 3/4" PVC spring rest. I then drilled my CPT hole accordingly. (See Louiec3's method here)



Hopper with a 1' clear magazine and a 16" CPVC barrel nested inside of 1/2" PVC. Standard stuff. I have yet to add a stock, but I'm thinking that I will use a chopper instead of a hopper, integrated into the stock.



Here's my +Bow with the same 16" barrel and hopper. It was my first homemade that I made about a month ago but haven't had a camera to post pictures of. I'm really happy with how cleanly it came out.



I use two extension springs bolted to the trigger to give it a very crisp pull. The dual spring set-up keeps the trigger and catch nicely centered.



Since everybody's doing it:



(Thank you andtheherois for the sealing tips on the front bushing)

Lastly, a group picture of my four favorite blasters with various barrels and hoppers:



I included the X-Bow (Zelda) because I'm thinking about homemade internals. Not sure yet if I want to make them myself or contract them.

[HasreadCoC]

1" plungertube, about 3" of draw, half a [k26], 3/8" nylon bar plunger rod, homemade priming finger grip, mainly for stock darts, shoots stock taggers ~60ft flat when I tape measured. The thing on the end is a cut up coupler, it helps keep stock darts from fish tailing due to the blaster's power relative to stock darts.

The owner is my 8 year old brother, who can barely prime it LOL. Powerful, but not so much that he cant use it in the house.

First homemade ever! Thanks to Ace!

[venom213]

I just completed a one of the most time-consuming and intensive projects that I've ever done. My goal was to make CAD templates in order to build a homemade Manta Ray shell in the style of Baghead's, with a few changes. This entire project from designing to finishing took no more than 10 hours, less than one third of the time it took Bags. Since most of this time was spent designing the templates, that time is no longer a factor in repeat builds. I opted to make this shell closer in size and shape to a stock Manta shell than Baghead did with his. I used 1/8" Polycarbonate instead of styrene. This shell is extremely strong and flexible. I sanded it all for to give it a cool frosted look. Complete write-up and templates coming soon.

This item is for sale, and it is likely I'll be producing these shields in numbers if there is enough interest for them. PM me with serious offers. I ship free to the USA, and I ship half price internationally. This thing is fairly light and can be broken into smaller parts for shipping with extreme ease, which greatly reduces the shipping cost.



Compared to my SadManta. No explanation of the name is needed.

[rego]

After six months of sitting on the shelf, I finally got the parts that I needed to finish this. But what! What could that be? Is it really? That's right. Instead of clear polycarb, I decided to use hardwood flooring panels.Still holding up after about ten shots so I think it's safe to say that it works.Unfortunately, because the material is layered and pressed together, drilling into it's side is a pita.

[SlightlySane813]

I think this is my first post in this thread.

My main homemade and first primary.

Writeup can be found here





My first plusbow, currently with a K18 for Grid Code. All cuts were made with a drill press with a bit that has lateral cutting groves.





And finish today is a Par55 that will be going to Nerfaholic.



Flat flush fronts are extremely sexy. (I got really lucky)



I contract R2L's and Par55's like the one's in my writeup, pm me for pricing.

EDIT:

Update on my plusbow with a new front attachment.



Attaches any N-strike rail to the bottom. For example my Cyclops with a shotgun adapter.



Grid Code here I come!
