finally finished my homemade e-mag conversion...

[Enigma4you]

Thats great

Wow... Smart parts is gonna sue ya but wow.<--joke

thats really impressive.

[funkmunky56]

wow. that's all I gotta say. congratulations. I hope to check this out at a big event sometime. It's inspiring me to get outside to my workshop and get some stuff done. After I'm done reading the forums, of course. --dave

What, no recharge port?!? :)

Seriously, though. Great job man.. That defintely shows that a smaller/lighter 2nd generation e-mag is possible.

[trains are bad]

I totally understand how that thing works, but I'm wondering where he got the parts. Radio shack? Also, what's a marlock board and are they hard to understand and work with? If there a site on the internet about doing electronics like that?

[Jack & Coke]

Very impressive! Great job! :)

.

damn nice work, clean.

amazing to think you not only a) got it all in there (morlock being small helps) but b) can get it to run efficiently on one 9V....in the grip at that.

the magnetic trigger setup sounds interesting.

props to you.

nice work electrican!

did same thing over a year ago.. except made the grip frame from scratch, integrated the rail into it (grip is moved .5" forward from original position and is .75" overall shorter in height). has E mode and direct mechanical override option. Optical trigger pickip with almost zero hysteresis. Integrated LPR as foregrip with internal plumming. Integrated snatch grip (not milled yet in pic).
Verified cycle rate of 20CPS.

old nasty pic of it before it got all pretty. :)


out!

hey thanks guys. I wish you all could put some paint through it. it's a fun gun.

it's definitely not the "ideal" mag set-up, but it really does shoot better than it looks, and that's what I like about it. it's fun to see people stare at it on the field and then finally say, "what the hell is that?" or "what's with the cocker reg on the front?"

sounds very cool nicad! have any finished pics? what solenoid valve did you end up using? single or double acting cylinder?

what mag valve are you using?

a friend of mine suggested integrating the lpr as a foregrip, but I like the gas thru grip, it give a large supply of 800 psi air. that's just me.

show us some finished project pics!!

Hi electrician,

Is this:



an updated electro-version of this:



?

If so, you can comment on the differences between the two in terms of trigger feel? Speed? Reliability? etc.

thanks :)

[rkjunior303]

it looks like the difference is in the trigger, with the bottom having the magnet operate the solenoid, that triggers the pneumatics within the grip while the top has the trigger actually operating the pneumatics, much like a cocker trigger (i think)

[the electrician]

yeah that's the same gun. the original design was a simple step in the direction I wanted to go. it was a mechanical 3-way behind the trigger, that sent air to a double acting ram that was being used as a single acting ram. the trigger was very short, but it was not as smooth as I wanted. if you held the trigger back, it held the sear down and the on/off pin up. not what I really wanted, even though it shot fast.

now the trigger is alot different. the opposing magnets replace the need for a trigger return spring (or spring return valve as in the case of the first mod) the magnet in the grip frame is adjutable, so you can make it super light, super stiff, or anywhere in between. it still has forward stop and back stop trigger travel adjustability, along with a switch activation adjustment. in other words, it can feel however you want it to.

it definitely is easier to shoot it fast now. it has "walkability" . I can't shoot it like that, but friends I have all said it walks easy. I've been running it at 12bps with a revy/empire circuit board.

I really can't comment about the reliablilty of the new set-up yet. the old pneumatic mod was pretty damn reliable.

[Jack & Coke]

Do both versions eliminate short-stroking (chuff chuff)?

[LudavicoSoldier]

I am very interested in this concept! Especially a purely mechanical version.. What small ram/manifold did you use? I'd like to homebrew myslef something up. Any additional info is appreciated, and unlike SP, I wont steal your design and try to patent it.

[the electrician]

well the pneumatic mod, almost eliminates it. it makes it really hard to chuff. mainly because the trigger pull is short. but it is still posibble.

but the e-mag mod makes it basically impossible to chuff. the morlock is set to a specific time and it energizes and then deenergizes the solenoid for the same exact amounts of time every cycle. so the valve is able to recharge as soon as possible every time. I've noticed that it will do 16 bps with no drop off when the solenoid valve is enegized for 30 msec. at about 20 msec you can squeeze 18 bps out of it, but I keep it at 30 msec of energize time. I then run it at 12 bps with the revy, so there really is no chance off drop off or chuf.

there is a sear travel adjustment that reduces its travel to the minimum required to release the bolt. this speeds up the recharge of the dump chamber a bit, and minumizes air consumption by the sear actuator cylinder. so it's stroke is only about 3/16" and it runs off about 80 psi ith a LvlX bolt and about 65psi with a standard bolt.
