    But then I'd have to make it fixed mounted (non portable) and only do tests from very close
    distances. Wouldn't be very exciting. The supersonic lego video was a dud, getting very few
    views... that is...

    Test results far exceeded my expectations. Was only hoping for 250 fps ( 75 m / s ) and around
    200 joules of energy with such a short barrel. Only took 140 psi of pressure to better this.
    Using my pum...

    Have been playing around with my low pressure launcher concept experimenting with large bore
    pvc pipe barrels of 25mm and nearly 30mm. Tested a variety of projectiles both skirted and with
    sabots. The...

    Maybe a heat shaped pvc prod would be the go. Lower poundage with more draw length in a longer
    redesign would make for faster easier reloading and possibly more performance.

    Effort is considerable. This isn't a weapon for the weak :)Seriously, I already thought about a
    longer weapon using the same prod, but with the sled attached to a 1:3 transmission. Power
    stroke is 17 ...

    How much effort does it take to cock it?

    How dangerous are paintballs at 800 plus fps?Did a improntu test with a heavy gauge detergent
    container filled with water and capped. Used enough pressure to exceed 800fps and shot from
    about 3 meters...

    Have definitely been infected by the power bug, wanted to improve on my best paintball speeds.
    Bought a new 200 psi pump and some poly pipe and fittings able to handle the extra pressure. My
    reasoning...

    Built a dedicated breech loading barrel for my pneumatic launcher. A improvement over my first
    attempt, this one being much neater giving 3 more inches of barrel for a total of 38 inches.
    Testing gave...

    Continued working on my low pressure launcher concept with a new design still using PVC
    components. The pressure vessel is now doubled in volume with the use of 40mm pipe. Instead of
    using a powered b...
