MAKING A ROCK HURLER by Jeffro
|
|||
|
==============================
|
|||
|
|
|||
|
This file is to make a "rock hurler", which is easy.
|
|||
|
|
|||
|
Take a 1 foot 1/2 inch to a 2 foot piece of PVC pipe that has 1 inch
|
|||
|
diameter and drill a 1/4 inch hole about 1/2 inch from the bottom through
|
|||
|
both sides. Run a piece of rope or string through the holes and tie it so
|
|||
|
it will never come off because it takes some wear and tear. You could
|
|||
|
also replace the string with wire it could hang on a belt and be more
|
|||
|
durable. I find that 1 foot 1/2 inch piece of PVC works best but 2 foot
|
|||
|
will work also. To fire it, you drop a rock into the end farthest away
|
|||
|
from the string. The rope or wire prevents it from falling out making you
|
|||
|
burn more calories to bend over and pick it up!
|
|||
|
|
|||
|
The next part is the hard to explain. With the flick of your wrist and the
|
|||
|
movement of your arm (like you're throwing a baseball) you can watch that
|
|||
|
rock land about 150 ft away. It is hard to explain in writing about your
|
|||
|
arm, but just experiment. You don<6F>t have to flick your wrist, but it adds
|
|||
|
more power. Step just before you throw to add more power. With practice
|
|||
|
you will find the right speed to move your arm and the right arc for the
|
|||
|
best distance. Remember that you have to take into account that the rock
|
|||
|
is sliding up the tube while your arm is moving, so it might come out
|
|||
|
sooner than you expect.
|
|||
|
|
|||
|
Another idea is super gluing a BB to the primer of a shot gun shell and
|
|||
|
hurling that, just don<6F>t kill Mrs. Johnson walking down the street! I
|
|||
|
haven<EFBFBD>t tried it but the shell probably will turn and not land on the BB
|
|||
|
so I would carefully open the crimp on the shell and take out the pellets.
|
|||
|
Then stick a wad of paper down by the powder to hold it in during flight.
|
|||
|
That would make it land right and it would be a lot safer (like you
|
|||
|
care!). I have an empty 12 gauge shot gun shell that I use a lot and I am
|
|||
|
working on a parachute system to bring it back down slow. I don<6F>t know
|
|||
|
what that could be used for, because it would be to slow to detonate a
|
|||
|
shot gun shell. If you have found a way to get it far and then the
|
|||
|
parachute opens, or what it could be used for, please e-mail me. I<>m
|
|||
|
also working on fins for the shot gun shell, since the empty one tends to
|
|||
|
come down with the tail in a big spiral. I have found that taping a 4 - 6
|
|||
|
inch piece of string to the side of the shell eliminates that problem.
|
|||
|
Make sure that about 80 percent of the string sticks out over the end so
|
|||
|
it will act like a fin. You could make a new hurler the size of eggs
|
|||
|
and go egg dead Mrs. Johnson<6F>s house. Put up a target on the front door
|
|||
|
and have a contest with your friends! She doesn<73>t care
|
|||
|
|
|||
|
>Oh well. That<61>s the rock hurler so have fun with it and use common sense,
|
|||
|
just don<6F>t kill your self
|
|||
|
|
|||
|
I take no responsibility for you injuring yourself, others, or destroying
|
|||
|
property.
