question on emag solenoid

[trevorjk]

would this be considered an Electronic reverse acting ram? if not please enlighten me

so essentially the pnuematic counterpart would basically be an autococker ram acting in reverse?

Autococker ram wouldn't work.

Autococker ram wouldn't work.

i understand that much

what i was refering to was the operation. as the emag solenoid is basically an eletronic ram that pulls in reverse (pulls plunger into ram casing) then pushes plunger back out.... just making sure one this.

now where as an autococker ram, is just that. air goes in the back forcing the rod forward. then air comes in the front forcing the rod back. now if you reversed the hoses coming from the 3-way (4way) you would essentially have an autococker ram acting in reverse such as the emag solenoid

essentially the same thing as the electronic ram on the emag but the autococker has a much larger stroke.

am i correct on this?

You are correct. If the hoses were swithced coming from the 3-way, the ram could be made to pull instead of push. Making an e-pneu E-mag? Oooh, do it, do it!

The emag solenoid does not 'push' back. It only pulls the plunger back into its casing for a brief moment of time, then the board cuts the power to the solenoid and the emag on/off pushes the sear back into firing position and the plunger comes back out of the case. It would be kind of like a spring returned ram, like on BKOs

E-pnumag! Now that has my attention.

All we need now is a half ram. Being that the on/off could reset the thing instead of relying on pneumatics. I bet something like this could be FAST. Then depending on what kind of solenoid/board is used to control the pneumatics, it probably would have eye support!

E-pnumag w/eyes!!!

I'm doing it! WAS solenoid here I come!

use a cocker ram, but dont plug the bottom end up. Maybe even enlarge the hole for totoal free movement of air. Or just use a solenoid like the mac on the front of a rainmaker and use the dual action ram.

not exactly sure on how im going to do this pnuemag.

but i do have a simple theory. wich im going to try before i go with a full on electro board. if im thinking right, a simple microswith to battary to solenoid connection would work fine. would make TRUE semi. when the trigger is pulled, it would mean the ram would actually be pushing the sear the whole time, untill i release the trigger. basically this will let me ACTUALLY chronograph my mag. and i would still have a true electro microswitch feal.

if i did it that way, i could truly chronograph my mag. and the battery consumption would be next to nothing as i would only be powering the solenoid, and not a board

still working on details, but basically its just putting the mini planet eclipse soleniod a battery and some sort of ram into a grip frame. with an LPR somewhere... basically taking the electro part of the cocker and putting it on the mag.

as for the half ram. i have been looking at the clippard manuals and all the others, and the best ram i could find to move half an inch up to at least 4 pounds was around 2 inches with out the stroke of the ram. so basically 2.5 inches. wich should fit in a grip frame just fine. although im sure i can come up with a better and more powerful alternative.

i just need to figure out the exact movement of the plunger on the emag before i can continue there

The emag solenoid does not 'push' back. It only pulls the plunger back into its casing for a brief moment of time, then the board cuts the power to the solenoid and the emag on/off pushes the sear back into firing position and the plunger comes back out of the case.

thanks for this reply. was just making sure and this helped alot

Im actually already on this one;

If I understand you correctly....

You want to go sans control board ?

If so , your assumptions on battery usage are far off.

The primary battery consumption in an E marker comes from firing the soleniod. Unless you can consistantly pull and release the trigger in around 20-25 milliseconds, your going to be using 2-3 times more battery power than the average e marker does.....at least.

In addition , you'll be dramatically shortening the life of the soleniod so you can add that costs to your newly inflated battery costs.

[RapidTransit]

I've thought about this long and hard already, but from my standpoint I do not want to waste time and effort making some sort of electro pneumatic ram actuated sear tripper but instead considering updating the valve itself.

hmm, so would there be any ways of being able to properly chronograph a mag, with a pure microswitch electric frame? unless some one has that programed into there board. but i have never heard of such a thing.

um, thats what the emag is already. its just a high end sear tripper
