Vortex block flame thrower (bb shooting only)
« on: June 16, 2013, 05:45:27 PM »
Oh hey, look. Another build thread by Yours truly:

... I think I work too much....

Alright so I've had this project on hold for quite some time now, but now that the howitzer is completed, Im going to go ahead and finish this one.

A vortex block uses a circular motion to expell high amounts of BBs using some type of gas(air). BBs are(usually) stored and fed from a large hopper, making guns more like a machine gun. Typical rounds per second(RPS) are around 60-70 but that number is easily brought up to  the 100's range.



I am planning on using my hpa setup I have for my Polarstar; that way I can still get adjustable fps along with other factors.

The hardest thing to get/make in this build is only one part; the vortex block. I was lucky enough not to have to cut it out of a solid aluminum block, or mold it out of auto body filler(although both options work). My block is made from a 3D printed plastic material. Everything else is just pvc piping and fittings. The trigger mechanism consists of a air gun for a air compressor. Very easy and cheap to find. The last thing to remember is the inner barrel. I just used a 600mm inner barrel(thanks to Warlord) and will secure it inside the pvc with plastic O-rings.





Should be done with the gun by this evening.

Feel free to post any questions or comments that you may have. Thanks for looking!

So it's basically finished but Im still going to put a hop up in it. I was testing it out in my drive way, and at the end of the drive way I have a table with a spray paint can. I had no thought process and and completely swept BBs across the area where the can was. Well after a few seconds a loud clang made me stop shooting and saw that the paint can had been pierced and pushed off the table. This thing has some serious kick!

Actually I'm just going to go ahead and finish this and leave out a hop up. It fires so many BBs that quantity alone will get someone, so no need for dead on accuracy. It's a flame thrower/ fast shooting machine gun not a sniper rifle. I'll post a video of it shooting either tonight or tomorrow.

Sorry I haven't had time to set up a video. But here is what it sounds and looks like.
