Can the sear be removed from the system? I think so.

[hill160881]

Or, what about removing the on/off together and replacing it with a pneumatic one.

That would be way cool. I think that is out of my abilities , for now

[kcombs9]

so this raises the questions, why was that part of the sear even there? TK if you see this Id like to know AGD reasoning behind that part of the design. maybe some issues we don't see yet?

simple enough - mags were Mechanical guns in the pre electro era, and their electro guns still have the ability to work in mechanical mode

not to mention 25+ years ago noids that small didnt exist

so your saying this wouldn't work if it was a mechanical mod? don't see why that would matter, I was under the impression you need the front part of the sear (where I hooks onto the bolt) to keep the bolt from going forward, but if this works with a noid I don't see why it wouldn't work in mechanical as well.

I'm not questioning the use of the full sear, just the part that Hill cut off

[DevilMan]

I have a sear that is worn (the part that was removed in the photo) and my mag will not shoot reliably. I don't know what to say.

Because on your marker you still need the sear. It's not a simple take it out and forget about it. You still have to have something to hold the on/off pin in place at the right length and such.

(YMMV)

BUT I do know that if it's worn, if you can get me a pic of it I may trade you one out.

Think of the ramp on the front of the sear that Hill cut off. Think of the interaction of that and the on/off pin. Think of the pin being down, and then being pushed back up to shut off the air flow to the bolt, until the bolt can make it back to a lock position as the bolt comes back the ramp of the sear. Then the air is shut off as the bolt comes back and then is released to shoot again after it latches, but it can't go because the hook on the sear has bolt held in place.

Then you pull the trigger, the sear drops out of place and away it goes. The air flow passes through and the cycle repeats. You know when it's out of time and you shoot and it leaks down the barrel, so you have to hold the trigger to get it to stop. You are closing the on/off. Then you adjust your sear rod length accordingly.

If it didn't need to be there, I'm sure it wouldn't be. Keep in mind that Hill is tinkering as he said on fine line between functional and disfunctional (on more than one level actually )

YMMV,

I believe someone had quoted Mr. Kaye not too long ago (last week or two) saying the front part of the sear was also a safety device. So the gun wouldn't runaway with nothing to stop it. Just think about it. Say the spring snaps or the back part of the sear goes, which both have happen. There's nothing there to stop the bolt. You would either have to shut the air off or let it run it's course.

In this setup. A spring snapping would just cause a huge barrel leak but if the back sear would happen to go. You would have a run away marker.

So you are saying that TK invented RAMPING as well??? SAWEEEET!!!!

I think you could get it to work mechanically, but it'd be difficult. Since Hill's Mod effectively reverses the sear cycling pattern, if you piped it all up purely pneumatically, whenever you held the trigger down, your bolt would stay forward and you'd vent gas down the barrel continuously.

You'd have to use a pneumatic pulse switch to control the dwell of the on/off ram. Someone on MCB was designing one a while back, but I don't think they ever actually produced it.

this is more what I was looking for, thanks!

also what efficiency will be gained? I under stand less ware on bolt ect.

p.s.

Not trying to debunk Hill and his project, I have projects of my own and I'm just trying to understand pro and con of this mod and maybe what I'm doing with my emag and noid.

Well then, removing the sear all together and installing the MPA directly under the on/off would be an easy mod you can do on your drill press.

[fierymartel]

How about removing the on/off assembly, tapping the hole, and then reinserting the top half of the on/off. Then, install perhaps a QEV that is fed from a 2-way solenoid or pneumatic valve?

[fierymartel]

or along those lines.........

[fierymartel]

I mean, we really just need a piston of some sorts in there, right?

This is the real danger. If something looses pressure it will go full auto until you turn off the air.


But like that will ever happen,,,,,,, maybe should not have said that .
