NEW Threshold Animation (GIF)

the other thread turned into a debate on functionality/modding/patents, so i
thought i'd start a new thread for the revised threshold animation.

it was confirmed by one source that the firing chamber air does indeed enter
where i suspected (hopefully more people can confirm this). there were also a
few errors brought up in the other thread so i fixed those as well.

so here's the new animation:



it's a blowforward spool valve (similar to ion). the rear chamber (firing
chamber) is fed a constant supply of air from the reg. the forward chamber
(green air) is controlled by a normally open 3-way noid. when the trigger is
activated the green air vents out and the orange air pushes the bolt forward.
when the rear of the bolt clears the back cap air travels down through the
bolt and fires the ball.

the animation shows the firing chamber completely emptying itself when a ball
is fired. this is not actually the case. since it's fed a constant supply of air
there will always be a bit of pressure in the rear chamber. it's just a little
easier to visualize the way it's shown.

i did this animation without the rear bolt o-ring because this is how the guns
actually shipped. if you were to put an o-ring on, it should seal the
firing chamber when a ball is fired. this would work similarly to the HE bolt for
the shocker and should give slightly better gas efficiency.

sorry, i don't even have the gun so i just went off the pic that was posted online.

i think the air actually travels through cavities milled into the body itself and
won't flow directly up those holes like i have it in the animation.

maybe someone who owns the gun and is more experienced with cad could come
up with some renderings. if they did, then i'd be able to animate them if needed.

i seem to agree with him. there does seem to be a few ported holes in the body where it would seem the air would be channeled to the bolt.

the fusion and the threshold have internally milled air passages if thats what you would mean

i do see a hole in the middle section of the body, like it shows in the animation, so it could possiably be how it works

i'm pretty confident that is how it works. i just meant that i couldn't add in the
grip frame/noid/reg/etc. because i wasn't sure where the internal air passages
were. i think this provides a pretty good example of how the firing mechanism
works.

So what is the efficiency like(?) since the operation seems to be a blowforeward version of a shocker.

I'm still a bit confused.

The Ion bolt has a tail much smaller in diameter from the head, so that with equal pressures in front of and behind the bolt, the forward air pressure has more surface area to work with, generating more rearward force.

With the Threshold, the pressure from both sides meets at that one oring on the bolt... how does it push the bolt back, against equal pressure from the other side? I was hoping the animation would clear this question up for me... I'd been wondering since the first diagrams came out... but I still don't see it.

I wouldn't expect much efficiency at all without the o-ring "mod" done.

After seeing this animation. My mod isn't as worthless as I first thought of it to be. Efficiency FTW.

And who said that it was more efficient in the beginning?
