Shell ejecting venturi gun
Posted: Wed Dec 24, 2008 2:18 pm
If you guys have seen any of my work, you know that I like simplicity and cleanliness.
Recently I started building a Semi Auto Nerf Gun. I'm still not done with it, though. I'm just that fucking lazy. I will finish it though.
But the progress I've made on it so far has already to proved that this design is too complex for my tastes. It's not anything that I'm incapable of building (although it may seem so because I haven't finished it yet) but there seems to be too much that could go wrong. (darts getting pinched, bolt getting stuck, cylinder rattling itself free of the barrel) I am absolutely OBSESSED with simplicity and reliability so I've started designing an even more simple gun. Here's a quick diagram I made and I'll give a little explanation as to how it will hopefully work.
There will be a spring loaded magazine set inline with the barrel. Within it will be shells containing lightweight* nerf darts. Each shell will be closed at the back.
There will be an opening cut into the barrel where the shell ready to be fired is located.
Perpendicular to that shell is a subminiature cylinder (retracted)
Slightly in front of that shell will be an inlet into the barrel for a QEV.
Upon firing, the air flow from the QEV into the barrel will "suck" the dart down the barrel sort of like the Vogt Pattern. I've tried this and it does indeed work, especially because Nerf darts are so light. EDIT: I'M RETARDED AND I WAS THINKING OF SOMETHING DIFFERENT. PLEASE IGNORE MY STUPIDITY AND THIS WHOLE THREAD FOR THAT MATTER. The reason for having each shell closed at the back is to ensure that only one dart fires and not the whole row.
After the dart fires, the submini cylinder will extend and push the spent shell out of the ejection hole. When the cylinder returns, spring pressure on the row of shells pushes a new one into position.
I will have to coordinate that QEV and the cylinder somehow... but that'll come later. Any comments/suggestions?
