I have found a topic about making a valve simular to a Baikal black bird airgun, I thought it was a good valve idea as I have a T from a push to connect air fitting, with a o-rings of 6mm in dia, perfect for a 6mm out dia steel tube.
Anyway, I was thinking about using a solenoid to pilot the valve, as it´s easy to open (somewhere around 3kg to open: hammer, return spring for the valve and hammer and friction between the valve and the o-rings), but I have made some coilguns, and I needed 1000uf 330v to shot a steel nail, for this gun I´m planing using only 12v battery from rc planes, is that possible to power a coil to pilot the valve? if it does, what´s the size of the coil I need?

- the coil need to power the hammer, return spring for the valve and hammer and friction between the valve and the o-rings, all I need is 3 kg max

I don't quite get how the valve works... Are the exhaust ports exposed to the chamber when the hammer is pushed? Seems like a lot of dead volume.

Yes the valve opens when the exhaust hole get in to the chamber(witch also will push a bb), not too much dead space, at least it won't matter much to the power as I will use high pressure. Back to my question, how am I going to make the solenoid hammer? I choose electric because I would have a chance of making a selection fire bb gun

3kg seems like a lot of force... I'm not sure about the power of solenoids, but it sounds like you would need a pretty heavy duty one to push 3kg.

The idea looks familiar
I had revisited the idea here.

I think the crucial idea is that it's not pushing directly but acting as a hammer, therefore accelerating a mass which then impacts the valve with a lot more force than if it was pushing directly, this is the concept I had missed.3kg seems like a lot of force... I'm not sure about the power of solenoids, but it sounds like you would need a pretty heavy duty one to push 3kg.

ok 3 kg maybe to much, 1.5 kg probably enough, and yes I only need a hit from the hammer, not continue pushing. So any suggestions?

That will work for sure, but too expensive, and i only need the coil, what's the sizs of coil that thing uses?

Pretty big, I have one different brand, coil is around 60mm OD and 85mm long.
Im sure Tech can shed some light on them.

I'm sure you can find something cheap at your local automotive parts store.
Combine it with a 12V battery pack and a momentary switch and you're sailing.

that one jsr linked uses a motor and screw to move in/out and is slow not like a hammer.
what about

you can replace the ram type think one his one with a eccentric cam

How many amp I need to power a coil like that? I don't want to use a motor because it's slower than a coil powered hammer

I would say a typical RC model/airsoft gun battery pack should give you enough juice to drive a hammer with enough force.

as i don't need the power to shot a nail, i think i can use a smaller coil, 4cm long 4cm od maybe? What type of coil should i use? Thinner the better in this case right?
looks like that one works now I have to talk to my dad about it holp it's strong enoughFine, this one then http://www.ebay.com/itm/DC-12V-Push-Typ ... -Electroma gnet-Actuator-10mm-0-8N-Holding-/280753202822?pt=LH_DefaultDomain_0&ha sh=item415e31e686
