well, it took me all of about 12 hours from inspiration to decimation....

The challenge:

I liked Mr. Plow's inline vortex design ALOT! its pretty genious, and even if he wasnt the orignal creator of it, it was still made so nicely that it inspired me to make one, somehow, someway. The whole inlineness of it just made it look cool and streamlined.

I was going to reverse engineer it purely by pictures...
AND make it better

The problem:

I dont have a lathe.

and the brushes just went on my dremel.

oh sh!t.

The solution:

Sorry if i led anyone on... but come on haha! I may be new to this forum but if i can understand how anything works, i can certainly make it simpler and most of the times better. I'm a mechanical engineer at college right now and stuff like this is what i live for, to keep my mind occupied while i sit through classes and what not. I love making up ideas in my head, and i seem to be getting better as i get older.

This design can be made by ANYONE!! and its absolutely devistatingly awsome. total parts cost was pretty much exactly $50 for EVERYTHING. I'm just a little hyped up right now cause i just got done working on it for 4-6 hrs, and its midnight, and i just poored the bb's outta my cloud i made last night and into this gun, plugged the air in, and not really expecting it to work on the first try pulled the trigger valve and pffffffffffttttttttttttttttttt omg!!! the sound of it perfectly ripping through a cardboard box made me giggity giggity haha. Here is what i made last night

HAHA a simple little cloud, that was my first venture into bbmg's. It worked great but the bb's deformed the soft copper barrel.

Needless to say i've just been running my mouth, so lets get down to business.

This design is just about identical to mr. plow's in concept however there was no lathing involved, just the use of the convienent snug fit of a 1.25 end cap in 2" pvc. the vortex block is "milled" from hard ash (the stuff they make baseball bats outta). the spring driven ram to reduce the size of the chamber is where i got creative. I've helped design concept paintball guns with a guy at smartparts before, and i gathered alot of that knowledge into this gun. well its really simple actually, the spring driven ram, is just a 1.25 end cap piston. this works perfect because its snug enough of a fit to reduce the ammo chamber size, but it also has a perfect amount of blow by to not crush the ammo. the blow by then aids in propelling the bb's, so nothings wasted. sweet.

Barrels threaded through a fliped around 1.25 end cap into the vortex block, using the included compression fitting.

theres not much more i can think of thats important to know, i mean just look at it its pretty much self explanitory, but if anyone wants a diagram, let me know. just to restate the obvious, everything to make this gun and my other two copper rifles can be purchased right from homedepot. i dont have a mille or lathe, so i have to be resourceful, and hell, i think this one turned out pretty good looking.

that looks rely nice can u make a video of it shooting?

Nice job, I'm glad to see more people using inline vortex blocks instead of the ugly T design.

Edit: I didn't really realize the air driven ram thing until after I posted. Really cool idea, with my SMG I was going to do a spring powered ram until I saw this, hope you don't think I'm cheating. Mind showing us a picture of the ram itself? And just one last thing, how big of a compressor do you use, is the ram an air hog?

i can not see any pictures

noname - no problem, the air ram is pictured below.

Unlike the spring driven ram, an air ram will expand to no limits as long as there is pressure, hmm kinda sounds like a projectile in a spud gun lol. simple idea, and it allows me to make a much larger ammo chamber than mr. plows inline.

to show this, heres my new inline, kinda inspired by the barrett m107, but of course, it does not actually look like it, so dont get all uppity you gun fanatics lol.

i through this one together tonight, but it still has the same problem the other one did, it leaks. mainly because of its design i suppose, but ill hafta put another oring groove in the end cap inside the chamber.

oh yea, i see that you sell vortex blocks noname... does that include inline blocks? if you need a cadd drawing of what i want let me know cause i would certanly like to have a better machined block than just the wood ones i am currently only able to make. thanks

I don't think I get it. Does the back of the gun have the piston to advance the ammo forward, and the front is just a normal BBMG? If it is, that's a pretty cool idea.

u r correct

Wow. It sound complicated but it doesn't look like it. I like your other copper guns better though.

Yes, I do sell inline vortex blocks; in fact, I don't sell T shaped ones because of the price of Bondo and the complexity needed. As for the "machining" of them, all I use is a drill and a hacksaw, that's all I have.

That second gun has a HUGEly long barrel! Bet it shoots hard.
And about the air ram again, thanks for the pics, but does it have to seal, or can it have a small gap? I'd think you'd need a seal for the best performance, but I think it would still function with a tiny hairline crack between it and the pipe. Does it matter a huge amount? I can never do O-rings right. When they do seal, there's WAY too much friction, so I try to make the groove smaller and end up with it leaking.
