    That's slick! I am thinking that the skate board wheels actually guide the pocket more accurately.

    This can set lines and top trees all in one go, and it even has a safety ! Click image for larger version.

Columbine had just happened so we had it film it rather than bringing it in, and the teacher just laughed hysterically when he saw it .

    If that is your product dude, get rid of that clear barrel immediately. Clear plastic is brittle as hell, and threaded clear plastic is asking to kill someone. There's a reason why no piping system on earth uses it.
    Clear plastic is indeed inherently brittle.

    I use these on occasion for longer shots. Just some aluminum turned down to fit in a pneumatic launcher . the "O" ring makes a big difference and will easily shoot over 200ft with 115 psi. I haven't done any real max distance tests with it but the first time I tried it I sent the weight with 200 ft of throw line that was tied to the corner of a small tarp up an over a 175 ft Spruce, it stuck the tarp 40 ft up the tree.

    Nice job. I was interested in sabots to launch the RobeKnight but have never gotten to it and realistically never will.

    Climbhigh, what's going on in your avatar pic?
    Looks like half rope runner half hitchhiker... is the HH dogbone doing anything besides holding the hitch? Looks cool, any other pics?
