As Nova pointed out, I wanted to add an integral suppressor, if I made the chamber the whole length of the barrel there wouldn't be any room for it. Making the chamber small makes it even quieter, and easier to reach high pressure.
It doesn't have to be a marker, anyone got a spare camera? Say Cheese  |

This one on the other hand, which dimensionally is closer to what I want to make with this marker project, was extremely audible, hence the desire for some sort of suppressor.
I'll do some chrony tests with the above when I get home to see what performance I can expect, as I didn't really test it using the 6mm tube as a barrel. |

"the red marker is the gun, blue is the pump"
"what's the green"

| I tried making the same, except a combustion pen gun. It didn't workout too well, so i ditched the project. I'm curious to see how this will turn out... |

I like the design and the concept...
I doesn't take much to move a BB down the tube at an decent velocity so I think your chamber volume is probably fine... especially with that PSI.
I look forward to seeing it in completion...
Starting to get ideas about my own mini now  |

| If you're familiar with high strength adhesives and have access to a reasonable variety of metal/strong plastic tubing, this sort of launcher is easy to make. I made a quick how-to for the pen gun project that might be of assistance here. |

This is the marker gun that I made I also made a shock pump to funny thing same thing happened to me that happened to btb didn't try to ryhme that but anyway. the check valve broke and the handle of the pump put a hole in the ceiling  . The marker gun is just like a regular large co-axial just smaller. it has a blowgun exstention for a barrel and it shoots through news paper it makes a pop so you should use a suppressor. |

looks like a cool little coax what kind of pressure do you use it at? and you must post damage pics
