Rock Sling





Introduction: Rock Sling

In this instructable, i will show how to make a sling. making a sling is easy, fun, and one of these bad boys can outclass any slingshot. Slings were first used thousands of years ago for hunting and as weapons. They were used in war up to the1700s in the British military weapon that the Calvary men used for long range hits. A sling was used by small man David to take down the giant Goliath in the bible. This shows two things about a sling: 1) it's a low status weapon and 2) in the hands of an expert it can be devastatingly effective.

Step 1: Materials

For this instruct able you need about 12 ft of para cord A lighter (optional) And a pair of scissors or a knife

Step 2: Starting the Sling

Take one loose end and measure out about three feet. Tie a knot there to mark it. Next make a loop (refer to picture). This part is kinda hard to explain. You have to take the side with the knot and fold it over the other string, and the pull it back over, making another loop. Grab the rabbit ears and pull them out evenly so the knot is next to the top loop.

Step 3: Weaving

Now pull the unknotted string under the first string of the top loop, and then over the next one, then under, over.then pull it through the bottom one and repeat. Each time you finish one part make sure to slide it to the end and tighten it. Keep doing this until you reach the end

Step 4: Tying It Off

Now take both loose ends and pull on them as hard as you can to from a pouch. Press your thumb into the middle as your tightening. Then go to the middle of the edge and tie a knot with the loose ends through the rabbit ears. (You might have to pull on them a little to get them to stick out)

Step 5: Finishing Up

Trim any extra cord off the ends, and go ahead and melt the ends with a lighter ( make sure not to touch the wax!!) now make a slip knot on one end, and a granny knot on the other.

Step 6: Using

Making a sling is pretty easy, but using one is more difficult. For ammo, you want to use something small and heavy, like a shooter marble or a small round rock. You can also make your own out of clay. Once you've inserted your ammo in the pouch, you put your index finger (any finger really, I just prefer that one) and then pinch the other end between your thumb and index. Next you sling. Teaching someone to sling would be difficult to do with writing, so has lots of great techniques.

Great for slinging eggs! Easy to get the hang of. Paintballs and rotting baby peaches make excellent ammo too!

I made this and I flung a rock from my fence two thirds across my backyard which is an acre

When I was a kid, my friend and I made slings like this, larger, to hold egg-sized rocks, went out in the countryside, and had a blast. Safety Warning: if you ever screw up and launch straight up, be sure to shout at your friends so they can all look up and avoid the plummeting rock! I was almost a "late" friend, but his errant rock luckily shattered on the stones right next to my feet.

How do i use this?

will this shoot tennis balls or no

The launching of the sling is not something I can include in this instructable, but I will soon make one on how to use the sling

I think he meant to give a more detailed description of the pouch

Very easy to make! However, I was having a little trouble with mine holding the ammo and thought it was a little long so I modified it a little to use three loops for a slightly wider pouch and made the whole thing shorter for more control (just personal preferences). Thanks for the instructable! Made both yours and mine in less than an hour ago and have already had so much fun with it already.
I put together an instructable of my own. Thanks for the inspiration!

but it's a nice sling.

Try making a video. it will be a lot easier to follow.

Wicked. Just made and have yet to test, sure it will be great. However, account for the amount of rope a knot takes up as well as the amount of rope you gain from slack.

Pretty fun!
Only problem i had was getting the ends to tie off nice after i weaved. Think i improvised well though

it was set up to weave, then all the sudden 1/4 of it was weaved,

Dnash2 what do you mean

please more descriptive on the weave for the launching part of the sling

Made mine last night really nice. I wonder how big you can go with the W shaped method of making a weaving lattice.

that is what i did to make mine, 5 wire nails in a scrap hunk of wood. made it a lot easier to weave the sling.

Amazing! It took me a while to realize when weaving I shouldn't tighten it too much.

I've not had a day off and over 3 weeks and I've been really bummed about that. The fact that I just made this has really just made my month. Thank you ! Seriously.

A better descriptive process of the beginning would be helpful. More pictures to start it off between step 2 and step 3. Cool finished product but not intuitive
