Sand down the bottom of the piece of CPVC so that the turret axis is not impeded.
Replace the barrels on your 2k turret.
I used the front of the pen and an old BuzzBee dart in the center of the turret to keep the barrels evenly spaced.
Use large amounts of hot glue to join the turret, the pen and the CPVC stub. If you want the turret to be easily removable, don’t get any glue on the coupler.
The turret is easy to remove, but sturdy. I still suggest opening the case if you desire to change from turret to single barrel.
Place all the internals back into the shell. I did not take a picture, but I surrounded the turret axis and air output with FBR for added stability.
Close the gun back up.
I found it helpful to tape some thin plate Styrofoam to the back of the turret, because mine was tending to shoot left.
I really like the versatility of this gun. The turret doesn’t decrease ranges badly. The added ROF is excellent for the circumstances I use this gun for. Around here, we use stock taggers because we don’t play in a huge area, and most shots are taken at around 40’ or so. This gun hits high 50’s singled and low 50’s turreted (with stock taggers and the pictured bungees), so that's perfect. I will test with stefans soon.
I know that people will question my use of hot glue for the turret structure, but I find that the plasticity of it allows the assembly to bend slightly without breaking, so I don't plan to change it. When it eventually breaks, I'll replace it with Plumber's Goop and epoxy putty, but until then, I like it as-is.
Questions or comments?
My project aim was to create a Disk Shot modification that kept the internal coupling and eliminated dead space, and to create a removable 2k turret attachment.
1 Disk Shot
1 Airtech 2000 turret
1 CPVC coupler
Foam backer rod
Phillips head screwdriver
Dremel with grinding stone
Hot glue gun
Scrollsaw (not necessary, Dremel or hacksaw will suffice)
Drill press (also not necessary, power drill will suffice)
½” drill bit
Open the Disk Shot.
Take your CPVC coupling and cut it as shown in the picture. There should be about ¼” left on one side before the stop.
Dremel out the back of the coupler until it will fit snugly over the lip of the old AR. I didn't even have to glue it after tapping it down with a hammer.
Dremel down the plastic support ring directly in front of the chamber until the coupler fits well. Do this for both sides of the shell.
If you only want to use one barrel, you may close the gun up now. You’ll have to Dremel the inside of the orange ring in order for the barrel to fit.
You’re done with the basic part of the modification. If you wish to add the removable 2k turret, continue reading.
Drill a 1/2" hole in the front of the blaster just below the barrel hole. Depending on how exactly you drill the hole, you may need to sand it out some. This hole is for the turret axis.
Take the body of your pen. I used a BIC Soft Feel. Any pen that has an O.D. less than the I.D. of the air input on the turret will work. Wrap electrical tape around it until it fits snugly in a small section of CPVC.
Put the small length of CPVC into the coupler. The rear opening of the pen should be flush with the hole in the end of the chamber. Cut the pen off at the front of the shell.
In the pictures, that thing appears sturdy enough to be run over by a car multiple times without damage. Good work.
@Bob: Tek 6 springs are actually decent. I use them in Nitefinders and get pretty good ranges (55' or so)
I finished it on Thursday, so I guess I can claim the second Rev.2 reproduction. It's awesome, anything that was a problem on Rev.1 has been completely fixed. To anyone who is making one, I definitely suggest sanding the polycarbonate all over as CaptainSlug did, it brings a whole new level of comfort to the blaster. I really like the solid core grip too, I was a bit sketchy about it at first, but after actually holding it, it's way better than the foam core grip. Right now, I'm in the process of converting my old Rev.1 one up to date, but once that's completed, I can forsee this thing getting some sort of dye job.
I can't wait to tackle another one, great work CaptainSlug.
Just as an afterthought, do you see a Rev.3 ever happening or are you satisfied as-is?
I had a similar experience, except the package came around 3 PM the next day. It was incredible service. My order was about $27, and shipping was $9.50. It came in one fairly large box and the long tube used for the nylon rod. If your order was just the springs and cylinder, and the rod, then I can't see shipping for you being too much more than mine.
Here's a question ... I'm asking here because this thread is no doubt read by several people who have done business with Mcmaster-carr before ... Is it typical to place an order in the early evening, and have a courier deliver before breakfast the next morning?
I still don't know how much the shipping charges are going to be, and although that's terrific service, I hope we're not talking $20 shipping for my ($15) order. But now that wouldn't surprise me.
I also live fairly close (>200 miles) away from the warehouse that my order was shipped from, so that might have helped.
Thanks a lot, great work improving an already phenomenal blaster.
All right, glad to hear it. Thanks a lot.
You'll have to print out the new templates and use the scrollsaw to widen the shape of the existing hole to accommodate the the round plunger rod if you want to change over to it.
My +bow. It was my first experience machining plastics with a scrollsaw (I know it wasn't recommended, but I wanted to give it a go). I'd say it came out pretty good. A few of the cuts aren't straight, and some of the holes didn't line up first shot, but the process really wasn't as painful as I expected.
The new trigger is MUCH easier to pull and far more comfortable than the old slider. My only issue with it now is the cocking handle, and it appears that Rev. 2 solves that entirely. I also need to hit that part up with the sander again. I'll be doing some minor sanding and comfort improvement over the whole thing, and probably give it a dye job, but it's done, and it's awesome. I can't wait for the full Revision 2 experience...I'll be one of the first downloading the templates.
Stole the words right out of my mouth...
And now I'm very very happy with it.
EDIT: Just one more quick question: Will the Rev. 2 supply list require any new things or more of some of what's on there? I'm in the process of placing a McMaster order and want to know what to get.
Rev. 2 is looking great, I can't wait to see the rest of the write-up.
EDIT: After seeing Blasphemy's post, I occasionally use a scrollsaw when doing large-scale work that would result in physical taxation otherwise. (or when I'm making a +bow)
I guess I deserved that...the only gun I added one to for actual war use was a 2k, since it had no good point to aim by. They did help (me at least) on longer shots, especially on guns with no natural sight line.
I'm inclined to believe that no one who has ever attended a nerf war and done relatively well has subsequently thought to themselves, "This gone is pretty cool, but it could really use a plastic tube on the top. That would make it way easier to aim, what with me forgetting which way to hold it and all.
And Falcon, I love that site. It was the first thing I discovered in the way of people who enjoyed tinkering inside plastic toys as much as I did. It led to my discovery of the NIC, and I guess I'm here today because of it. I for one would be sad to see it go.
Rork: Thanks! These things are clearanced all over the place, I'm going to pick up a few more too. It always means something to me to get a compliment.
BlackFox: Thanks, the ranges do seem a tad low but I plan on overhauling this thing to the extreme. I'm going to do everything possible to squeeze the most performance out of this thing. TTG springs are a bit more powerful than the stock spring. Loghomestore foam is excellent quality and very durable, it's just, HUGE. It only fits in 19/32" brass and larger.
Thanks for all the compliments!
1/2" CPVC coupler
Teflon or Electrical tape
A better spring (opt.)
Hot glue/Plumber's Goop/your favorite adhesive
I minimized my Disk Shot. Most minimizations hack the excess off at the inner wall, but I wanted the retain the ability to use the ammo holder, so I cut it off even with the trigger guard. The holder is very solid when popped in, but can be removed fairly easily for whatever reason.
Open the gun up. Try not to lose the catch spring, it'll try to pop out. Remove all the ARs.
I replaced the spring with a Tech Target spring. When I give this thing a complete overhaul, I'll put in something stronger. I also wrapped 2 layers of Teflon tape around the plunger head. Note* Teflon tape isn't sticky. If you do more than one layer, it'll naturally stick to itself. Putting the O-ring on over it will hold it down perfectly.
Cut a 5/8" long piece of CPVC. Adhere it to the end of the plunger chamber. I suggest gluing the two orange pieces together, and to the plunger tube itself. Once the adhesive is dry, add a 1/2" coupler.
This step is mostly for cosmetics, though it does add a little stability. Take the orange ring from the front and Dremel it out until CPVC slides through it with no resistance.
Put all the internals back in. Don't forget the two screws in the plunger chamber, and don't forget the catch and trigger springs. I added a bunch of huge Loghomestore FBR for silencing. It works well for that if nothing else.
Close the gun back up. It looks almost completely stock from the outside.
I find that a 3 3/4" barrel works best.
Ranges are about 55' flat with a pair of mini-bungees.
If anything's unclear, don't hesitate to ask.
OMC: [timidly raises hand] Are Zero's the ones that have 5/8" heads with 1/2" bodies (or some combination of two different foam sizes)? I seem to remember reading something about them on one of the old Nerf pages.
EDIT: Never mind, I was thinking of "Webbies". I remembered the name of one and the method of another.
Good start though, I look forward to seeing the rest of the mod.
I wanted to throw the "fun" feel back into my Crossbow, so I got this off the web and tweaked the colors until it was right. I'm sorry that I can't help you any more than that. (It seems to be the right size as-is)
Renegademilitia: The range decrease appears to be no more than 5', which is what I was hoping for. I'm still not that happy with the ranges though, I'm going to be doing some more tweaking.
Nonsense: The barrel doesn't actually nest over the air output hole. There's a short bridge, but the O-ring nearly eliminates leaking.
It is assumed at the beginning of this writeup that Part I has been completed.
1/2" CPVC endcap
1/2" PVC couplers (2)
Loctite Epoxy Putty
1/8" polycarbonate (opt. but strongly suggested)
PVC style pipe cutters
Cutting wheel attachment
Hot glue gun
Here we go!
Start off by putting a small length of PVC into one end of a coupling. Repeat this step for the other coupling.
Using a Dremel, grind out the ID of the PVC for each coupling until 1/2" CPVC slides through it smoothly.
Grind down the OD of the 3/4"CPVC until it can be inserted into the other end of the PVC coupling. The piece should be about 2 1/2" long.
You now have the completed inner part of your turret.
Take a 10.5" piece of 1/2" CPVC, line it up as pictured, and cut a notch out of 1/2 the circumference.
Now take the Dremel to the front of your Crossbow ( ) It should look about like this. (Mine is a little big, there used to be an internal 2k integration and the barrel was a little below the new hole)
Now using liberal amounts of hot glue and cable ties, attach the axis to the plunger tube/coupler. I used a few small 1/8" polycarbonate scraps for additional reinforcement, and I strongly suggest doing so.
You can now put the internals back in and close up the gun. (I didn't but I didn't know. You can).
Cut a 2 3/8" piece of 1/2" CPVC. This is the "bridge."
Stick the "bridge" into the coupling, and add the #9 O-ring. Use another piece of 1/2" to tap it in better. I'm going to glue the O-ring in because it kept falling out, see what works best for you.
THE TURRET!!! It can have up to seven barrels. I find six to be a perfect balance though.
It is removable to be rear loading and clippable.
On the 'bow:
The Crossbow has a Falcon Super Strap. I really suggest putting one of these on each and every primary you own, they're awesome. I also printed out a original Nerf sticker to put on the side. I love it.
Advancement is an easy motion. I find that I can get off one shot every 1.25 seconds or so.
Ranges (fired flat at shoulder height) are in the high seventies and low eighties. My Crossbow seems to have bad ranges, I'm still experimenting with barrel lengths and types.
Good luck, the thing's a pain until you really get the hang of it.
Took 10, because I split things up more than NH requires.
Heh, apparently it's only 85 pics, I left out several from the total number I posted on flickr, mostly because of the duplication of effort. 85,000 words huh? That'd be a helluva thing.
I'm working on the integrations now, we'll see how it turns out in the long run.
Heh, if only I was that good with video editing.
I'll see what I can do with my wife's camera, hers actually has a video mode. And I need a good mask... Maybe I'll get a steampunk flight helmet and goggles. "
I think I can handle it...would you say a year's experience would suffice?
About the video editing, if you'd use it a bit, I'd suggest looking into the Ulead VideoStudio line. My sister was an amateur film director, and you can do some pretty good stuff with it. I don't know what version they're on now, we have 7 and 9.
I can attest that a stock Xbow spring is substantially weaker than a +bow/AR15 spring, I can fully compress the former with my bare hands and can barely shorten the latter. I can also attest that that that spring is the most beastly coil of wire I've ever touched, so I'd imagine any gun with a piece of it inside could chuck a dart a fair distance.
EDIT: Thanks hereticorp
So that took what, 9 posts?
Great job, I love all your work.
EDIT: I counted. If a picture's worth a thousand words, then your writeup, without words, is worth 85,000 words. Now that's a post I'd like to see...
