Detent on vortex bbmg

Unread postAuthor: pacoeltacco » Tue Aug 30, 2011 9:12 am

Hey guys, I was wondering if anyone has tried a detent on an in-line vortex bbmg. I'm not sure that it would work, the rof is too high, but let me know what you think.
Thanks,
Spencer

also, could someone point me to a how to for how to make a detent, I know about the o-rings, but how do I mount those?
Thanks,
Spencer
P.S. Once I am done with my in-line vortex gun I will post pics

No reason why it shouldn't work just as well in an inline vortex.

As to mounting the o-rings, you need to sandwich it between a threaded fitting, something like this:

do you think that 120 psi will be able to push the bb through an o-ring, or is there another way that I can make a detent?

I don't understand why you would do it, I think the rof is too high to feed a detent. Jsr seems to think otherwise though.

Rate of fire?

The flow of BBs out of the barrel depends on the flow of air out of the barrel.

Once a BB gets stuck in the detent, that flow stops until the BB pops out.

Vortex, cloud, mag fed, none of this makes a difference in the circumstances the way I see it.

The issue with airtight detents is having the BB in the barrel leave the muzzle before the next BB can block the breech.

I'm willing to be proven wrong, of course ;)

well it seems that with a vortex the bb in the barrel should leave the muzzle before the next bb can block the breech as the bbs have to get agitated again

Cool, I actually saw that on youtube, but how did you do that, is there any way that you could explain to me how it works?

There's no easy way to determine the popping pressure ahead of time, just start trying o-rings. If you go to http://www.mcmaster.com/ there's a huge selction of o-rings.

Yeh my Grandpa has a huge assortment of o-rings, but I wanted to make sure that that was the right decision before I wasted his o-rings. Also, will a small shallow hole in the barrel make a detent work. Also, I have a .25 in lamp fitting for the barrel, and the part that clicks the lamp is a lump on the inside of the barrel, so I think that that may work, but I will try that, and if it doesn't work, then I will add an o-ring, but I still don't get how I am going to fit the o-ring into the barrel, it's not like I can just make a indent on the inside of the barrel to fit it in place. Any suggestions would be greatly appreciated:)

Once the BB in the detent starts to move, you then have flow from the chamber through the barrel. Consider the rate of fire most BBMGs have, it takes milliseconds for the next BB to get to the detent.

The good thing about having the o-ring in a threaded fitting though is that pop-off pressure increases as you tighten it, so there is some level of adjustability.

You can do it with part you can buy from the hardware store, a few fittings would need to be modded, slip to thread fitting need the end drilled to fitting the OD of barrel and the coupling cut down so the two male fittings can bottom out

I would use PVC parts because they have thicker walls that will give more area for the O-ring.
