airforce condor hammer valve

Hello,

I am on the drawing board to make a airforce condor exact replica, especially in the firing mechanism.

My plans, that i did and work, are making the gun a little different as when you pull the cock notch, it has to stay there and when you trigger, it goes backwards.
Wich is not like the gun at all.


From what i understand, the valve (hammer receiver) is on the airtank and the hammer on the gun. Am i right?



Does any one has blueprints, or even better, an airforce condor?

Yes!

Thanks a bunch!

Where have you got that schematics?

So the slide is getting hit by the hammer, wich hits the valve?

Thanks

Far cry posted them in a thread of mine a while back. I don't know their origin.

The hammer strikes the breech slide which in turn opens the valve. The breech slide must be closed before firing.

So thats why the breach tends to unlock just after had fired (see vieo), as it is hit by the hammer.


I wich so much i had a big lathe! i can only work with small size with my drill, but it works well and i know a dude that as made one witout a drill...



Does anyone here knows well about 16 ounce co2 bottle modding?

I have heard that the bottle must be heated in water to be able to get of the pin valve, and that the thread is not npt...

I'm unsure about that particular size, though I removed the valve from a soda stream CO2 cylinder and the threads fit 3/8" fittings fine. A lot probably don't.

Getting the valve off was painful, I gripped the cylinder in a pipe vice and clamps, then used a large wrench with a pipe as a lever. (make sure it's empty first)

This design is certainly suited to being made on a lathe.

I could be very interested in that lathe, as its one of the cheapest and smallest on the market.

Do i need any suplementary stuff or everything is included?


I would be making a contest soon where i can win up to 3000$, with a lot of intermadiate prizes, given by the governement. Its called expo-science and i will show off my little line tracking robot.

Demon, this is my opinion, formed by reading your posts...

I don't think you have a level of knowledge that you should be messing around modifying co2 tanks.

For your own safety... do NOT attempt to modify any pressure vessel, or its valve.

If you insist on going ahead with this "plan" then do your research...FIRST. Learn how to calculate the forces involved and the materials and techniques required to safely deal with those forces.

Machinery's Handbook is an excellent resource book, which contains the information you would need. They don't "give it away", but it is well worth the price IMO. It can be had for less on ebay, and you don't need a "current" copy either. The formula you'll be needing, simply don't change.

I think you misconsidered what i said.

I am not noob enough to try playing with liquid co2 without a lathe yet, and maybe even if i had one.

I wanna use a 16 oz co2 airtank as air chamber cause it looks like the airforce condor one. Air pressure woul'nd go over 160 psi(my bike pump) and i hope getting at least 5 shots( someone as already done that).

Thank for the book link, i would really like to get in machining so i can finally make all my plans.

Bob Craske's page is an excellent resource.

Hi,
I know this forum page is a bit outdated but I couldn't figure out how to post a new topic

I was wondering if you could explain to me how the valve actually works: I know the hammer hits the breach slide which pushes the valve, in turn opening the chamber; but wouldn't the power of the hammer spring keep the valve open?

Thanks all help is greatly appreciated!
