New Bolt Action
Posted: Thu Dec 27, 2007 10:48 pm
So i started making my prototype bolt action for a tennis ball barrel and was wondering what everyone thought of it. It is a 2.5" barrel with a couple of 2" - 1 1/2 bushings glues together. right now it is only a little bit longer than the uh breech but will be extended to cover the slide for the bolt handle so pressure doesn't escape when fired. other than that the bolt is very very tight (seals well) in the barrel and was thinking about cutting grooves for orings but want to fire it a few times before cutting into the bolt to set orings in it. anyway like i said this is just a prototype not actually set in a real barrel yet, so i'm always open to suggestions about anything i can do better.
Updated New Title I finished the prototype and integrated it into a new tennis ball barrel for my big 1 1/2 pneumatic which will be remade considering the valve is too far forward on the over under style.
Anyway here are some new pictures of the integrated barrel/bolt action system. I had to lengthen the bolt so that it covered the bolt handle slide in the closed position. in the open position the bolt slides back far enough so the tennis ball can be loaded. It take a little push, something that a spring fed clip could easily handle.
I'm going to find a nice meaty spring to go inside behind the bolt to automatically slide the bolt forward on it's own or with a little assist from the shooter because it does take little push to pop the tennis ball past the tapered lip into the barrel and hopefully to keep the bolt closed as i do not want a forward slide lock. There is however a rear slide lock to lock the bolt open so you can load a new ball.
Now based on this design would anyone have a way to make this a semi automatic as far as the bolt system goes, i already have a design for the clip.
Any input would be appreciated.
