Catapult for shooting Targets

Made this up today to help me with shooting Arial Targets

 

Nice catapult. I am going to show this one to the kid. He will like this.

Never seen anyone store extra arrows in their pocket. Why not if they are just practice tips.

 

Oh yeah I been keeping them in my back pocket for years they even sale a leather pock sleeve that goes in your pocket for that to.

 

Being that your using a string , you could place the launcher across the field or directly at you as birds don't always fly away .

 

Looks like the ideal set up for returning a neighbour's dog's turds back to the dog's owner's property.

It has occurred to me that using a long shank screw driver as a stop for the catapault / trebuchet arm, gives a fixed trajectory (though mass and shape of projectile may allow of some variation).

you may be able to vary the trajectory by adding additional holes along the vertical axis of the timber to alter the position of the screw driver - arm stop.
