Hopper...

[akaddis]

I am making a painball gun and i currently have a tee, (with shaved stops) fitted over the barrel with a hole in the barrel (with o-rings to seal off air). I currently just use pvc as the hopper that connects into the top of the tee. since the pvc is sealed on the top.. it wont allow air to leak into the hopper. Now i want to buy a real hopper, but i know that it isn't air tight (in fact its like 2 pieces screwed together...is there any way to make some sort of air powered bolt to push one ball forward sealing off the air and then the bolt will come back automatically? Or would it be better to seal the hopper and do it like that? A bolt would be preferred since sometimes the hopper double feeds.


Thanks
