  • Hey guys, it's Adam from Tested and I heard you, we heard you, here at tested

  • we know you love the One Day Builds and so do we

  • and here comes one right now.

  • But we also promised that more One Day Builds will be coming more frequently starting now,

  • and today's is really really cool

  • Still very popular is the secret santa NERF mod I did last Christmas

  • and today is another NERF mod.

  • This is without a doubt my favorite NERF gun I have ever seen.

  • It is the "NERF Rival"

  • and it fires a hundred shots in a row out of this hopper.

  • This is what it fires these little yellow foam balls.

  • Ooo perfect!

  • But a hundred shots in a row is...

  • ...nifty

  • but maybe improvable,

  • so I want to modify the NERF Rival so it fires...

  • [thunk]

  • ... a thousand shots in a row.

  • Uh-huh. I'm gonna make a much bigger hopper

  • and I will also aestheticize this.

  • Here comes today's One Day Build: NERF Mod.

  • [techy intro music]

  • Now the folks at NERF are geniuses at firing

  • safe projectiles in innovative ways and the mechanism of the Rival is

  • actually worth going into some detail about because I'm really impressed with it

  • The basic mechanism for firing these balls operates like a pitching machine

  • right on the other side of these two panels are

  • Two spinning wheels that when the ball gets to them, "Fook!" It shoves them out just like a pitching machine

  • But how it gets the balls to those spinning wheels is even cooler

  • So there's a couple of parts to it on the left side here

  • You see these little gear wheels and then on the right side, you see that little black belt

  • So what happens is when you fill this hopper full of balls

  • You pull the first trigger, which is down here,

  • [mechanical whirring]

  • and you hear that

  • That's the wheels spinning up.

  • Then you pull the second trigger and that activates these agitating wheels and the conveyor belt

  • [thumping]

  • [delighted laughter]

  • [thumping]

  • [whirring stops]

  • Oh?

  • [whirring and thumping]

  • Oop! [laughter]

  • Sorry Joey

  • So here is my overall plan for the mechanical aspect of this.

  • The hopper that fires the balls...

  • There it is.

  • That's the whole thing. This holds a hundred balls.

  • I'm gonna add a magazine onto this that holds a thousand balls

  • In addition, I have some other mods I want to do

  • I've got some Picatinny Rails, Red Dot Scope and some other aesthetic details that I've drawn out.

  • But first and foremost, I need to figure out how big these magazines should be

  • and so I need to do some volumetric testing with a thous- Wow, that feels really cool

  • First I need to work out the volume of how big these magazines need to be to hold 1000 shots

  • I have a couple of pristine pieces of foam core here

  • Let's say... that...

  • ok so...

  • [drawing]

  • [slicing]

  • [slicing]

  • [snap]

  • [sticky tape sound]

  • [sticky tape sound]

  • [slicing]

  • Well this gonna be great

  • Whoa, okay.

  • [astonished laughter] That's heavy!

  • All right that just comes up to here

  • Yeah, I like the dimensions of that better.

  • Let's see what I got here.

  • Ooo!

  • Wow, I got it kind of exactly right so by my volumetric estimation this size for a magazine

  • Is awesome, but it is only holds 900 balls. So

  • It needs to be a little longer so 3.3 inches taller, so it needs to be

  • 34 inches. Let's say 34 inches 34 inches

  • I am NOT doing a single magazine. Oh, no, I'm not doing a single magazine

  • I'm doing a double magaz- a double magazine

  • which means that half of 34 is

  • 17. [laughs] that took me longer than it should have

  • Yeah, so now we're getting into the design because I'm not gonna make these straight magazines

  • Oh, no, I have bigger plans. I'm gonna make these curved magazines

  • Cuz come on that's gotta look

  • It's got to look the part

  • one more sheet of foam core to figure out the exact curve and then and then and then

  • I'm gonna start cutting this out of acrylic. Yeah

  • so here's what we're gonna have is we're gonna have one magazine on this side

  • and one magazine on this side. Right?

  • Like that, like a like a Flying V

  • I thought they might be upright. But no no now I think they're gonna be like this

  • That's gonna be frikken fantastic.

  • That's... I'm really excited about that.

  • I also noticed that with the completely parallel sides when I tried to dump this out

  • the, uh

  • The balls got stuck in there.

  • So that tells me that actually I want my magazine

  • To be thinner at the top and wider at the bottom, uh-huh

  • I'm gonna cut out four pieces of eighth inch acrylic that are gonna be the main body of the magazine

  • [whispers] wow, that is a big gun.

  • [whispers] What is this? Yeah.

  • "NERF RIVAL MAGAZINE"

  • "GUN"

  • "TOP"

  • This is a fascinating mathematical problem.

  • My question is... I'm going to cut out a strip here that's 17 inches long

  • and I'm gonna cut out a strip here that's 29 and a quarter inches long

  • and they both taper from the bottom to the top

  • but [stammering]

  • Actually, I can just choose.

  • It's a gradual taper

  • I just need to cut two strips 29 and a quarter a long,

  • and two strips 17 long and then figure out

  • what this end distance is and what THIS end distance is

  • and then draw a straight taper between those that's pretty straightforward. Okay.

  • Since the sides of my magazines are curved, uh

  • I need a bend in my

  • acrylic and

  • It just resists that a little too much for me

  • So I have a lab oven that we bought for the shop that will heat this plastic up to a nice gentle

  • 150 degrees Fahrenheit and soften it so I can get it to make a curve.

  • Okay, so there's...

  • ...those two pieces, let's just let those sit for a few minutes and see how they do

  • There are a lot of different approaches I could have taken to making this curved box.

  • I'm taking, like, the fastest, kind of sloppiest way

  • because these will be in a V so you won't be able to necessarily see if they don't perfectly match each other

  • the edges I'm gonna clean up, And they will be a little bit rough around the edges,

  • but I'll hide those crimes with some other techniques.

  • So I'm basically moving for speed rather than perfection.

  • I can make this box a lot nicer if I had to

  • but I don't have to.

  • I only have a day to build this so we're moving quickly

  • Alright, well my first magazine is mostly glued up and I'm quite happy with it.

  • Again, it's sloppy, but we'll clean it up. I've done a basic

  • Weld-On thin weld bond number three here. I am now going to pull this out

  • [boop]

  • of its

  • holder, and I'm gonna add some Weld-On 16 on the inside up here for structural strength before I-

  • For structural strength? For structure before I pull off all the tape

  • meanwhile

  • I'm gonna throw the other two pieces of plastic that are the curved sides of the magazine

  • into my lab oven and we'll get the second one going.

  • This is all going really well. I'm very pleased with how this looks.

  • Weld-On 16 is a thick weld bond.

  • "Weld bond" means that it melts both sides of the material it's gluing.

  • And Weld-On 16 is effectively model airplane glue

  • They're pretty much the same thing and it's the same thing as Weld-On three.

  • It just happens to be thicker.

  • It's got more plastic in it. I believe it's got plastic in it or..?

  • We've actually reached the limit of my knowledge of Weld-On 16, but

  • it will set up and provide some genuine structure here in the corners

  • and we should be able to pull it out after lunch.

  • Lunch?

  • Yeah, we actually do take lunch here.

  • The other thing that Weld-On 16 does is it bridges gaps. Like the thin weld bond does not bridge gaps very well

  • Whereas the thick stuff does and I do have some gaps in here because I did not build it incredibly perfectly.

  • Alright

  • I have cut one magazine out and it is

  • We talked about this before it's not pretty but it will do the job for what I need it to do

  • But I also just want to see how many balls this actually holds

  • Ack! Ack.

  • [gentle thunder of NERF balls cascading into magazine]

  • That's a very comforting sound isn't it?

  • [gentle thunder of NERF balls]

  • It's like distant NERF thunder

  • Holy crap, I seem to have overestimated

  • [laughs]

  • Well, so the plan was that each magazine held 500 balls

  • But this is a thousand

  • [stammers]

  • I kind of knew it was gonna hold more than 500, I made it a little bit wider

  • But because this material is thinner than the foam core that I was using clearly I way way missed my mark

  • But this is not a bad thing. It's actually a really good thing.

  • I've been thinking about a Flying V of

  • magazines and the problem I have with it is that I've got

  • the two volumes meeting above the hopper and I'm worried that they'll get clogged up with each other and at the agitator

  • inside the hopper won't

  • be agitating enough to actually cause a free flow of balls down into the hopper

  • so the fact that one magazine holds

  • all thousand is actually really good.

  • So I'm gonna go with a single magazine. I'm gonna modify my design a little bit.

  • I'm gonna go with a single magazine and the other thing that's really nice about it

  • Is this first magazine that I made is really sloppy and the second one is much cleaner

  • I've often said in the past that whenever I make something I usually make two or three of it so I can screw things up

  • That's what happened right here. This is not the pretty magaz-

  • This is not the pretty magazine. This is the pretty magazine

  • That's the one I'm going to use. So the next stage is to pull this out of its clamps, trim it,

  • and then attach it to my hopper. All right, here we go. Want to hear the sound again?

  • [whispers] It's a lovely sound.

  • [gentle thunder of Nerf balls cascading into bucket]

  • I hear you're asking "What is that thing? What is that?" This is a plexiglass scoring tool

  • Specifically for working with acrylic or "Perspex" for our friends over the pond

  • Yeah, it just allows me to round out this edge and this is uh really looking pretty gorgeous

  • So number one I can glue this down

  • Yeah, I can totally glue that down and then it's always going to

  • Yeah, okay. So there's that

  • One. Two is...

  • There that's that's what we gotta do. That's that's that's what we have to do here. So

  • Hotoobuh hubah [laughs]

  • Can you tell I'm in the excited part?

  • So I want that to be glued down there

  • I'm just bypassing one of the safety mechanisms here

  • Well, that could be the title of my autobiography

  • [laughs]

  • [mechanical whirring]

  • Hey fires with an open hopper

  • [whirring]

  • Haha, alright so cool now

  • This is yeah. This is the exciting part. And now I get to cut this thing up so that it fits all this.

  • I can't make it offset like this cuz I can't build that much structure.

  • You know, what?

  • So I had this beautiful Red Dot Scope that I was very excited about

  • But I may have to make it a parallax scope

  • So sorry, I haven't filled you in on all of my thought process

  • I went from a double magazine system to a single magazine system

  • So originally it was gonna be a Flying V one here one here

  • Now I thought "Since they both fit a thousand I'm just gonna use one

  • and maybe I'll just do a single side of the V so that I can still see past this

  • with my red dot scope"

  • But I'm gonna be running around in a skirmish,

  • a theoretical skirmish,

  • with like this much weight hanging off of this thing?

  • That's a recipe for disaster.

  • I want my weight up-right and center.

  • So I am going to

  • Do it like this

  • Yeah, yeah. Yep

  • let's say down to about there and

  • This one too, and I got to keep this upright

  • Just nontrivial

  • Good I'm inside of all the structural members here.

  • [robot accent] Time for cutting.

  • And it's nice it feels like this is actually acrylic

  • Which is good. It means it'll glue nicely

  • To what I've already got but let's see here

  • Yes, yes, oh yeah!

  • [satisfied laughter]

  • Dude I did not expect on the first blush

  • For that cut to go so well

  • That is really awesome. I'm very pleased with how

  • This all kind of gels. It's kind of incredible.

  • Ok

  • So

  • I don't have any. Yeah. No, this is this is this is yeah. Yeah

  • I'm trying to think about what I might have done wrong cuz when something goes

  • Like this well on the first blush, I always expect that somewhere along the line

  • I've messed something else up

  • But I don't think I have so I think I'm going to start getting some glue on this puppy to hold it together

  • Normally for a build like this, I would use a weld bond for this as well

  • But I want a little more structure out of it. So I'm actually using

  • cyanoacrylate [super glue] but instead of just straight accelerator

  • That's this stuff the spray accelerator that kicks C.A. glue really fast

  • I'm using baking soda, and we're doing that because it'll actually provide me almost some like genuine gusseted strength

  • That

  • It's the biggest structural problem of the whole thing

  • How to get the magazine onto the gun full of balls

  • And I believe that I have achieved it

  • Moment of truth time. One of several.

  • That comes in. That comes in. It locks

  • [very satisfied evil villain laughter]

  • Oh, I love absurdity

  • [mechanical whirring]

  • Okay, cool

  • All right

  • Yeah, yep

  • Ahhhh ya ya ya ya ya

  • [whirring and thumping]

  • [satisfied laughter]

  • [whirring stops]

  • That's fantastic

  • that's um

  • That is what we call "working"

  • Remember I said we were going to hide some crimes?

  • That's what I'm about to do now it's time to take care of some of the aesthetics of this

  • I'm also going to make a lid for the magazine so it can be closed

  • And I'm going to clean up that little [non-word sound]

  • A few more hours of work, and we should be well along our way.

  • Let's see here

  • Fifteen...

  • Thirty...

  • Alright

  • Now it's time for some detailing

  • The the gun itself is already pretty gorgeous.

  • But I'm gonna add some

  • I'm gonna kit-bash it. That's what's gonna happen kit-bashing.

  • Have I talked about kit bashing before?

  • I think I have but it's worth covering again kit bashing is the process of adding detail to a model by using

  • existing model kits so you're using the parts and pieces of other model kits

  • for purposes they were never intended.

  • Kit-bashing is how all the Star Wars spaceships were built. It's how

  • You know, oh

  • Yeah, this will be nice

  • It's you know, at Industrial Light and Magic, I kit bashed on a daily basis, and it was heavenly

  • Oh, look at this. Ah, I've got some good stuff here Oh,

  • Mmm, yeah, I have some special stash for my kit bashing habit

  • What you do to one side you want to do to the other

  • That one's gorgeous, that's it. Bye

  • Yep, yep yep.

  • [calm music]

  • Alright

  • [satisfied laughter]

  • [satisfied laughter]

  • [mechanical whirring]

  • Okay

  • Yeah, that's good. That's not bad. Yeah, nice and solid. I'm very pleased with the solidity

  • So I have some things to add to this

  • I got a bipod that I want to put on the front and then I've got some

  • Picatinny Rails to attach to it. I've got a red dot scope

  • Maybe I put a Picatinny Rail off to the side so I can see it

  • You know or on the ooh, maybe even on the magazine

  • [imitates gun sounds]

  • Like that.

  • [mechanical whirring and imitation of thumping]

  • I have to admit to you

  • I was thinking about just masking this and painting this because I'm feeling lazy and like I didn't want to have to

  • Understand this whole construction in order to take it apart

  • but to be honest the value you get out of taking a thing apart in order to paint it is

  • significant and real so I'm going to do it

  • [upbeat music]

  • Here, will you shake this for me?

  • The thing about masking is that it's

  • astonishingly tedious

  • If it's tedious to you, it means you're doing it right.

  • Masking just takes time and there's no other way around it

  • but the rewards it gives

  • the dividends it pays

  • Is really significant. So what I would like is on the on the gun here

  • I like these these details on both sides and they feel like, they feel like heat shrouds. Like they're

  • Separated from the heat of the main gun

  • So I'm gonna paint them a bright silver

  • falling off to black

  • the rest of the gun will remain red and it'll look like the thing gets really hot and you hold onto the silver part to

  • Protect yourself from the heat like a shield. Then I'll take a wash and I'll get inside all of these holes.

  • Uh, it's shaping up really nicely. This is a really fun one.

  • So if I surround each of the masked areas with black before hitting it with silver

  • I actually hide a lot of my crimes

  • of masking because the black goes into the interstices

  • and

  • hides

  • Where my masking wasn't perfect. It just goes dark. Yep

  • All right let's see here. Yep, yep, yep, yep. Okay. Yep

  • Okay, did I get all that?

  • I get all that?

  • I think I did. Alright, here we go. Hi-ho silver.

  • I think that's pretty good

  • like I said

  • It's not perfect, but I'll be able to hide some of those crimes later on

  • Okay, so I'm gonna take off a whole bunch of this masking see how we're doing

  • Even taking masking off, while lots more fun than putting it on, is tedious

  • Also, I don't know what your shop is like

  • But if it's anything like my shop as soon as you're done making a big ball of tape, that you've peeled off something,

  • It's really important that you throw it at somebody

  • I'm kidding ... throw it to them, so that you can play catch

  • Yeah, that's feeling pretty good. I like that. I'm very pleased with that. Oh, uh, yeah. There we go

  • Aaah, that's good enough

  • Umm

  • Alright, so

  • [satisfied laughter] What am I missing? What am I ... oh my god, frack, I totally forgot

  • [satisfied laughter] it's shaping up

  • See isn't that cool.

  • Ahh dude okay. All right. Here we go

  • Moment of truth

  • Time to fill the magazine, I'm pretty happy with how this whole thing looks it's been a

  • Genuine one day build. One day ... this is ... This is this is one of those ones that's actually a day

  • Ladies and gentlemen, I give you

  • The 1000 shot ... NERF Rival magazine. Okay gonna put this in. Oh this is ...

  • So pyched!

  • Ha! There, wa wa wait, I got a turn on my site oh

  • Oh yeah, oh yeah

  • Bum-pom (♪♫♬)

  • Dom-pom (♪♫♬) I got a bipod. I got a red dot sight. I got a NERF gun and I got a

  • thousand rounds of ammunition

  • Ha Ha Ha Ha Ha Ha Ha

  • Ahhhhhhhh! Ha Ha Ha Ha Ha Ha Ha Ha

  • No good build is complete without a proper test and I've come to 3210 Productions in Marin County

  • California where I used to work actually, uh, to do the test of the ultimate NERF mod. Today's query?

  • Dinosaurs

  • [dramatic victory music]

  • Ha Ha Ha Ha

  • Whoo!

  • Aaahhh!

  • [dramatic music stops abruptly]

  • [panting]

  • All right, take a break dinosaurs

  • [laughter all around set]

  • #@%&$*

  • My, my arm is getting exhausted.

  • Dino: You haven't even gone through like a fifth of that yet.

  • Adam: No.

  • [dramatic victory music]

  • Aaaaaggg!

  • You have to shake it every now and then it's a lot of weight of foam balls. Come on.

  • Come on. Come on.

  • Ha Ha Ha Ha

  • Ha Ha Ha Ha Ha Ha Ha Ha

  • Ha Ha Ha Ha. Oh my god, I'm actually getting tired.

  • Ha Ha Ha Ha

  • Whooooo!

  • [techy outro music]
