The way you drew it, pulling the trigger on the blowgun will just empty the chamber through the blowgun - you need to reverse and and trigger connections on the QEV.

Do you want this single shot or multi-shot from a single fill?

yeah i just realised i put the qev in the wrong way and no just one pull one shot cycle bolt refill and shoot.

If you open the breech with your left hand and insert the projectile in the barrel with your right hand, whats holding the gun? :D

You also want to limit the bolt travel. In your design, if you let go of the bolt in the unlocked position, the barrel will fall out.

the issue with the bolt is a drawing error it will actually be closed and to the loading question it will have a bipod attached and rested on a table or i y even try to make a magazine of some sort

Good design buddy, it looks pretty complex do you think you can do it ?

It looks very similar to the one in H.M Buckley Air pneumatics have a look there and see what you can find just search on youtube and you can see people who has created airguns from that book :)

Just don't set your standards to high :) Good luck

yeah im pretty confident i have made a airgun before but it just looks way to ghetto for my liking im pretty good and using machinery thanks to my dad allowing me to play with dangerous tools from a young age so i think i can get it done im gonna hope fully start the machining tomorrow so ill take lots of pics and keep you all upto date throughout my build.

Really? :? Hope I'm wrong, but that statement just REEKS of entitlement...which is horse shit. We are "entitled" only to that which we first earn.

Somebody had to work to provide you with that mill. See a connection there? :wink:

:)

I'm quite sure there are a great many people in this world (blind, paralyzed, sick and dying) that would gladly trade places with you just so they could work once again. Stop sniveling.
