    hi,

    I need to shoot a 300gram (11oz) projectile (a small bag filled with lead balls) up into a tree. The bag has to go at least 30meters high.
    Also it would be nice if I could aim ;).
    Oh, and the bag pulls a 2mm rope with it

    I'm thinking of a 2,5 meter pole (in 2 pieces so it remains portable)
    wide fork at the top (Joergs monster slingshot style)
    50cm bands of TBG, no tapering (heavy ammo)
    3 strands on either side
    big enough pouch for the beanbag (or handgrenades/moltovs in case of a zombie-invasion :D)

    in a second stage (when legths of the pole and the bands are determined) I would like to add some kind of trigger/release system

    Anyone thinks this is possible to make?

    and being just a kid (according to my wife) I allready ordered 3 meters of TBG

    I was thinking the same thing as Be. You can find videos on YouTube of this very device being used (I've seen it used, very cool) to see how it operates. There was a guy on YT that also posted a video showing a custom trigger mechanism he developed for this device, though I don't remember the link :(

    Indeed, that is what I need, BUT

    I'm thinking of a homemade for less than 300 euros since I'm climbing for fun (geocaching) and not as an arborist who makes some money using it...

    I would use an arrow shooter. Woodworking people use it to climb in trees, shooting an arrow with a thin fibre over a fork and pull the thick rope with the fibre over the fork then.

    At my home there was an often used way to neighbours in front of the house. So i used two rolls of toilet paper in a bag with a fibre on throwing over the house to pull a rope then connected it and secured myself for working on the roof. Nobody was harmed, no windows broken.
