Solenoid Tripping a Mag Sear?

[WalkingTarget]

I've had a small thought recently...

Looking at the E-trigger kit for the Tippmann Pro-Custom, it seems like the solenoid is mounted in the very bottom of the grip, connected to the sear assembly with a long rod.

i'm just wondering (from the expert minds here) how hard it might be to use a double acting linear solenoid to trip an Automag sear, using the ULT kit for the on/off.

i know it probably has been thought of at some point, but it seems like a very logical way to retrofit a classic mag to be electronic or 'electric assist'.

the two problems i seem to be running into with this idea are the entire geometry/component placement of solenoid and linkage, and where to place the power source (currently looking to Li/Ion cells with a built-in recharging circuit or hotswap for Li/Ion batteries.

I will try to draw out what i am talking about later when i have some time, unfortunately my MS Paint skills are about as good as Smart Part's R&D department.

thoughts?

Love the way you added the SP jab for no reason... but then again no reason is reason enough. lol

ohh, there's reason, i've fixed 5 ions and one shocker in the past month, all had from-factory defects that could have been fixed with better design/components



back to the topic at hand though


mag sear attachment would be placed near the on/off side.. i will have to try to use paint later today to show how it works...

hmm my friend and i had this idea last year and were starting to work on it but kinda got distracted and made a gauss gun instead... I might get back to work on this.

whats different than a spydermag besides less modding to the sear

So wait, you want to make an E-mag?

nope!

was thinking of a different placement for the noid, pressing up on the on/off part of the sear rather than like AGD has thiers,

also using a smaller board, and Li/Ion power source to make it rechargable (as in cordless phone batteries) so everything fits in the grip


heck, you don't even need much of a board for my idea, just a capacitor to build charge for the 'noid from a battery and the resistors and such so that it doesn't blow the noid, add in a circuit to make sure that the dwell is appropriately short, and something like this can be constructed from parts from Radio-shack.

I'm pretty sure you'd need a huge solenoid to directly trip a mag on/off. The only reason the emag is able to do it with it's size solenoid (and thats a pretty big solenoid) is because it has a lever working on its side. I didnt pay much attention in physics but I'm pretty sure the force required to directly trip the on/off would be greater and would require a HUGE noid.

[WalkingTarget]

i've yet to do the calculations, but with a ULT kit installed, and the correct noid pushing in the right location, it should be very do-able. the big deciding factor in the little work i've done so far is finding a solenoid that will fit inside the grips... not because there isn't a noid small enough to do the work, but because finding one that is slim enough will be a challenge.


either that or i'm just going to be lazy, buy some parts and make a pneumag.

[personman]

Hmm.. It might be possible but I dont see it as being feasible. Even if you did find a solenoid that worked well, it would probably suck batteries like no other. :/
What would work though, is having an electropneumatically controlled ram in place of the solenoid.
I dunno to be honest.

Try extending the lever that the trigger rod typically attaches to all the way to the bottom of the frame, and use the solenoid at the bottom to take advantage of the leverage. You'll need one with a longer throw than actuating the on-off directly, but it won't require nearly as much force, and might open up your options for a slimmer solenoid. Getting a battery and board in there too then becomes the fun part.

that's why i'm thining of Li/Ion batteries... they are small and pack a punch when it comes to power... i really don't feel like spending $400+ on a set of Emag lowers when i eventually get the tinkering bug :P
