Need help on my Project Inline Vortex BBMG

Unread postAuthor: FelipeL » Tue Jul 23, 2013 2:00 am

First of all hi guys, i would like to state that this is my first ever post on SpudFiles, and that i am a mexican/american so my english is not the best, but understandable.

So i read a ton of threads and visited the SFWiki and got inspired to build an airsoft gun :idea: , me and my friends play airsoft, but we are just beginners and most of us havent even buyed a gun and are playing with cheap soda bottle/ballon weapons (from witch i love the sound they make and the echo you hear like half a second after shooting, almost like a sniper :lol: ),

2 out of 10 have buyed a gun and only one has an AEG, the rest are Springers , and of course i want to ravage the land AND START NUCLEAR WAR :twisted: :twisted: :twisted: :!: :lol: (korea)
Ok, so now after my grand intruduction this is my plan:

Imagine a pvc 1 1/4" hollow tube about 8 in. long, plywood vortex block (this is an Inline Vortex btw if havent noticed yet) on one side and an end cap, and on the other side a scrwable pvc end cap thing and a plunger, you get the idea, basic Inline vortex design, but here is the twist, i am basicly gonna transform the chamber into the mag, so yeah the gun without the mag/chamber shall look incredebly ridiculos!!! :P but it would have a quick way to reload,
The barrel will have a detent, the spring/ball design i saw on a post about a jsk guy who i see on almost all the posts (not sure if it was jsk, maybe jks?) he is Very helpfull, full,
i'l try to find the tightest barrel i can find, 6.05 maybe?, now i live somewere in all of the state of chihuahua and airsoft guns are pretty much imposible to find,not even in wallmart, just hunting rifles, i also saw that the detent jsk posted about could work as a hopup mechanisim, im screwed as in finding airsoft parts, made FOR airsoft,

Now this is the MOST IMPORTANT PART of this post, What sources of air can i use that are portable and last a good 5-10 min. of short burst firing?

My ideas are mini portabe compressors, effectively making my build an AEG, however it will be quite expensive for me as my max budget is 30$ US Dollars, another idea is a pvc air tank that is backpack mounted, like a flamethrower design, also i've benn thinking about storing the air inside the chamber/mag but i cant find a soloution for a trigger,

Now im quite limmited in my knowledge of parts and terms so Please dont come up saying advanced parts unless you describe them to me, keep in mind im in mexico and go to buy in mexico, if you know how the parts are said in spanish also call them that way or else i might not know what im even looking for and by im i mean the sales peapole.

Thanks in advance :)

Bienvenido!

Makes sense so far

The barrel will have a detent, the spring/ball design i saw on a post about a jsk guy who i see on almost all the posts (not sure if it was jsk, maybe jks?) he is Very helpfull, full,


I hate that guy :D

Jsr, wouldn't a 6mm outer diameter with a wall thickness of 0.45 give an inner diameter of 5.1mm?

Thanks guys for all of your posts.
Ok so thanks for the welcome Jsr, i'm glad you understood this, so i don't like buying stuff of the internet, maybe i will go to home depot, aka spud depot and try to find a good barrel there, if i can't i think i will stick to using brakeline. (how muck does this cost?/precios?) I read your post Jsr (So it was Jsr) and i think it's a good example, just one question:

Is a 2l. soda bottle gonna stand up to some good pressure safely? i think it might blow up, i think you said in your post that the air in the bottle lasted for 30 bb's, it gave me an idea as to what to do.

Here is a video of the flamethrower design i might use

Now Dart Guy What do you mean by "Bullpup"?

Sugestions for my build are welcome Thanks!!!

If you can find a couple empty fire extinguishers (which I'm sure you can) try plumbing two of them together and filling them to about 150 psi or so. Then you can connect that to your gun for a portable air source.

I meant that you should have the load "mag" behind the trigger to maximize barrel length with a short gun.

Hey Guys :D , i have come up with an idea for an incorporated silencer (Not Removable) in a bullpup inine vortex, i still don't know how to post image files (GIMP) so i will have to describe it to you.

Okay so, inline vortex, on the back of the gun (almost in the stock) and then the barrel, sealed in a chamber (yes, the whole barrel) independent from the one with the bb's and the vortex block, and at the end of the barrel some holes a reasonable distance from the start of the barrel to give the bb time to accelerate.

The Chamber is filled with some fluffy material, like sponges to dampen the sound, preferaby something that doesn't rot in water if you get the gun wet in that river over there in the arena, and also durabe.

"INLINEVORTEX" "TUBESIZEOFBARREL" "ENDCAP"
" COUPLER" "SPONGE"

And for an important part, the original chamber where the vortex block is, surround the walls of the most parts you can in something fluffy again, i'm thinking Foamy the thick kind, but you might have some problems related to the plunger so this is optional.

So, what do you think? :P Oh and so how do i upload images?

PS: Also, how do i change my profile pic?

I will be posting my gun design for all to see as soon as i get the hang of JPEG's and PNG's here

Fluffy material isn't really helpful when it comes to sound dampening. You need baffles to create turbulence and slow down the exiting gas.

This video deals with firearm silencers but basically airgun silencers work on the same principle:

Is this to stop the BBs rattling around?

Oh and so how do i upload images?


MrCrowley wrote:For PhotoBucket Users:

Photobucket allows you to have an album, meaning you can upload all your images to one place and keep them there.

1) Go to www.photobucket.com

2) Go to 'My Album'.

3) Click 'Browse' and select the picture from your hard drive.

4) Click 'Browse' for the other boxes if you want to upload multiple pictures at the same time.

5) Click 'Upload' and wait. It can take a few minutes depending on how busy PhotoBucket is and your internet connection. If it's taking more then 5 minutes, try again.

6) Your pictures should now be in your album.

7) Below the picture there should be a few boxes, go to the one titled 'IMG Code' and highlight the link in the box and hold 'Ctrl+C'

8)Go to your post/topic in Spudfiles and paste (Ctrl+V) the link into your post.

9) That's it, if done correctly when you submit your post your picture should automatically display in the topic.



Using The SpudFiles Uploader:

If making a 'Quick Reply' post, go to Step 1, if making a new topic, go to Step 2.

1) If you are making a 'Quick Reply', click the 'Add Reply' button so you're taken to a new window.

2) At the bottom of the post box, above the 'Submit' button, click 'Browse' and find the file on your computer.

3) Click on the picture file you want to upload, type in the 'File Comment' box, any comments you want to say about that picture.

4) Click 'Add Attachment'.

7) Wait for the page to refresh and load, your first picture should be uploaded.

8)To upload more pictures, just repeat the process.

9) Once you have uploaded your pictures and typed out your post, hit the 'Submit' button. Now your post should be posted in the topic. If uploaded correctly, the pictures should all show up in your post.



Uploading A Preview Picture For The Showcase Section:

When making a new topic in the showcase section to post your new cannon, you have the option of having a preview picture next to your post in the 'Showcase Section', this will tell you how.

1) In the 'New Topic' window, scroll down a bit and find "Enter url for thumbnail provided by the uploader", then click the link 'HERE' which will open a new window.

2) Click 'Browse' and search for the picture you want as a preview, on your computer. Click on the picture you want.

3) Click 'Upload' and wait.

4) Highlight the URL from the box that appears.

5) Copy the URL of the newly uploaded picture into the box back on the 'New Topic' page just above where it says 'Thumbnail MUST be uploaded HERE'.

5) Once you have typed out your post and uploaded the pictures of your cannon and the 'Preview Picture', click the 'Submit' button and that's it.

6) You must upload your Preview Picture that way, no exceptions.

Good luck with your BBMG, Felipe.
Couple of tips, though.
Your vortex block needs to be as smooth as possible, so if its wood you will need to sand it down VERY fine. An easier way is to line it with PVC pipe, or an aluminum coke can.
You say it will be an AEG? An AEG stands for "Airsoft Electric Gun".
Be very careful when using BBMG's for airsoft. The pressure needs to be regulated low enough that it will not hurt anyone. What JSR refers to as the "jackhammer effect" must controlled, if you are going to play.

Shameless self promotion:

Check out the pictures of my vortex block in my M16 BBMG (the link is in my signature). You will see an example of lining the wood with PVC. No damage or wear to this day.
