I had to watch those clips a couple of times because I couldn't tell if it had fired or not.
Excellent work making such a tiny launcher  |

When I first saw the title, I read it as "Pneumatic penguin", and wondered what you were doing with small flightless birds. Then I clicked the link and all made sense.
Nice work, looks good. Have you considered using a presta valve instead of a schrader? You don't need a pin to depress a presta stem. |

I know! I kept looking at the title from the corner of my eye while typing out the post, convinced I had written "penguin" by mistake hehe

Thanks very logical suggestion... though can a presta handle the sort of pressures I'm likely to subject it to? |

Do you have any idea of the muzzle velocity achieved by your launcher at 200 psi with a 2mm lead sinker?
BTW: very clean, very cool gun. |

I've given up trying to get a chrony reading, the projectile is too small and the chrony isn't seeing it  ah well, as far as power goes, I can tell you it will go clean through a folded piece of A4 paper at 200 psi  |

Fair enough, I usually aim for high power, but felt like something a little different. Also, this is only 200 psi, I'm sure things will get a little better at 400... |
