Sling Tube :D




About: I enjoy Hiking threw the vast wilderness, and using my two hands. I am currently a medical student. Recently I have been studying theory and religions. The last time I used instructables I was 14 or so! HA, ...

 Hear I will show you how to make your own Gravity Hammer, it is really a mace type weapon that uses force to launch anything you store inside outward at a high velocity.

I am not responsibly for any or a injure, or involvement with the law on your part, so think safety! Be sure to where proper protection and be sure to secure all protection.  

I discovered this masterpiece when i was sweeping and i happed to break the broom and I saw a hallo inside then it hit me. if i put something inside would it launch the answer: yes! also a little inspiration from halo have me a ideas to.

Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Tools & Supplies

Hear are all the tools and supplies needed to complete the project. 




Broom Handle, the cheep metallic "ish" one
Heavy dute rope 
Tape of any kind

Step 2: Preparing the Barrel

 In order to retrieve the barrel, simply break open the broom stick with the hammer. Be sure to break the barrel to the length that fits you.

Grab your pliers and begin the clean the edges of the barrel, also use the hammer to pound the broom back in to a circular circumference. 

Step 3: The Sling and Handel

Grab a  length of rope about as long as your arm. and tie it around the end of the barrel, then 3/4ths the way on the other side, and tie it again to the end of the sward and re tie ti to the 3/4th part, the Brade is optional

Use the tape to wrap around the handle to give grip and your finished.

Step 4: How to Operate

Grab the hammer  by the handle and insert a projectile in to the barrel and swing it as if it were a sword and watch the magical forces of sentrifical force launch your projectile toward the object

    I did something very similiar where it was a circular container for holding ammo and a cardbord shipping tubethat could fit seventy rounds inside although not very accurate, if you were hit you would see a rain of fire.

    No, the only forces at work on an object rotating on a tether are Centripetal force, and inertia, Centripetal is Latin for center seeking, as that is what the object in question does, the tether does its best to pull it as close to the center of rotation as it can, while the inertia of the object is always trying to keep the object moving in a straight line, which is (usually) always at right angles to the tether. However, if the tether breaks (or is released) the object in question will fly off at a tangent.


    There is such a thing as centrifugal force. It is the term historically used for centripetal force and the refined version of centrifugal force is used in Lagrangian mechanics


    Historically, but also incorrectly. Also, the "refined version" is described as the theoretical "generalized force" which is (disregarding the fact that they are both physics-related,) irrelevant to the more practical gravity hammer made of a broom handle.

    It is for a sling and a conformable handle grip, with guard.

    Umm... I'd have to say it'd be a little easier to use a hacksaw or some other official tool to break that open; cleaner cut, a little better looking.

    As clarification, what scale would we be looking at when you say, "Be sure to break the barrel to the length that fits you."? Is it from elbow to wrist, or some other measurement?

    Sward? Sintrifical? Spell check?

    The browser Google Chrome has a spell check option built right in--it has fixed my mistakes quite a bit--but it wouldn't catch something like...

    '"Hear" I want to show you'

    I also realize English isn't everyone's first language. If this is the case, I am embarrassed by my nit-picky critique of your interesting and informative instructable.
