I know, I have already printed your diagram dewey-1, as soon as I get all the parts I will start making it. Could you teach me how to adjust the fire rate? Ps: I have to mod the valve again, apparently the 12v battery I bought isn't as strong as a car battery :(

Make sure to print the one with the comments on it. Not the early one I posted.

What type is the battery? Picture and/or link please.

Are those NiCd AA size cells or something else. A link will help me solve the problem.

I know NiCd sub C size will work.

Yes they are Ni-Cd AA cells, well I would post a link buy I bought them from a local electronic store :roll: and they this type is all they had, hope they works :?
And well... is burst fire possible without complicating too much? Sorry I know I had said that it´s not useful but I found out that a lot AEGs have that option :oops:

If they are Ni-Cd they should work OK.
Is there any part/model number on the battery?
There usually is for identification purposes.

it is possible... though do you have a loading mech on that ?? if you don't then what's the point of adding that feature ??

It would be more practical to get an aeg (I assume you want it for airsoft ??). Seriously, you need an air chamber for that an as much batteries as you need for an AEG. So what's the point ?


Too be honest I don't like your design at all. Your using electricity to do what it does worst (I hope you get what I mean). This wouldn't be such a big deal if it was machined, as that would help to reduce friction, but it isn't. Lol I probably sound very negative.

The valve stem is polished on a lathe first :wink: low friction.
I want more power than a AEG, this valve+800psi :D and a AEG needs more battery, my goal was a gun simular to baikal blackbird.
Again, this valve is also the reloading mechanism, see the first diagram I posted.
(I bet you were very positive if I had used the 3-way+cylinder option :wink: )

Now you get it :D
nah really dude... solenoid 3 way valves do have a small solenoid inside - the only difference is that it is machined and a proven design that serves as a pilot valve for the main valve... so essentially you don't need much electricity to open it
