Picture of Piano-wire Slingshot
A small but powerful slingshot made using 1mm gauge piano-wire and ordinary rubber bands. A strong magnet at the base of the handle holds a cluster of steel shot.

Step 1: Materials

Materials for the Piano-wire Slingshot are as follows:

1. A length of 1mm gauge piano-wire. I stumbled on this in a hardware store but it's also available from most hobby stores. It is sold in 1-metre lengths and ranges from 0.3mm to 5mm (yep, I made a slingshot with 5mm piano-wire too!). In this instructable, you'll be working with a length of 360mm.

2. Rubber bands. Use however many you like and whatever thickness you like. As I mention in the video, I prefer to twist several ordinary rubber bands into a kind of bungee-style cord. This makes for a much safer slingshot (for the user, not the target) and reduces the risk of a whole band snapping and hitting you in the face.

3. Slingshot handle. 100mm length of dowel (10mm diameter) or rod (10x10mm).

4. Handle binding. Cord or tape is needed to bind the slingshot frame to the handle. After using electrical tape, I finished my handle with black heatshrink (also found in hobby and electronics stores).

5. Ammo pouch. This can be made from any soft pliable fabric. I used a short length of ordinary shoelace for mine, because it's readily available, easy to work with, strong and soft.

Two Words - Surgical Tubing
Thera band tubing for resistance training is widely used by may slingshot enthusiasts. They even argue over the pro's and cons of tube vs flat bands LOL.
I prefer the Black "special heavy" tubing. You can go through amazon or ebay for it or even just google ti :)
Where can I get piano wire? I'm looking for mebbe a bit stronger 2mm. Can you get it in stores, or is it off the internet? Thx for answering
 I sense... inspiration!!!

That reminded me when I cut this tiny tiny wire off and flew away. One moment it's there; another moment it's gone! Time to post my version (later, still have an Aikido session after 2:30 pm GMT+8)
FAIL!!! :( looks like I'm going ahead with my other instructable...
hey chluaid, I'm one of the many people who love your flash work and have bin annoying you about waterlollies, but more on this topic great insturctable and if you made a larger version i have an alternative more heavy duty ammunition for it , if you still have an old mouse (not the laser or light sensor type ones) remove the ball from inside, then take an Xacto knife and cut the rubber/plastic coating off it, and there you have it a much more powerful heavy duty solid iron (I'm pretty sure) ammunition
whats a water lollie
Its... like a drop of water.... but.... look at his videos he has on newgrounds.

cool.. yeah I did make a piano-wire slingshot out of 5mm piano-wire which is incredibly sturdy. The wire was a nightmare to work with, especially cos my tools are mostly for smaller-scale projects. I attached a proper slingshot band to it (the type you buy in stores) and I use 8mm lead shot, and of course you can't go wrong with good old glass marbles (14mm). An old mouse ball sounds like great ammo, if a little difficult to come by. That's the kind of ammo you fire away then spend hours trying to find it again. I do have a great (completely different) use for those balls though.. I'll post another instructable later. Thanks for the comments!
also there is a version of ammunition that i call "Saturn shots" what you do is take the solid iron ball from above, then take a electrical connector ring (i have no idea what its actually called but i have about 26 of them and I'm wearing on as a ring right now) and use a belt sander (Recommended), file, or sand paper and make it sharp then push it onto the ball in a very snug fit (see it looks like Saturn with spikes around the middle)

Jeez dude that shit sounds evil :D My kinda thing heheh
oh really, how do you feel about explosives
Damn gettin hit w/ steelshot hard would hurt like hell =p
CHLUAID! OMG OMG OMG OMG OMG Dude, you're awesome! I love your work and simply cannot WAIT for Waterlollies! (SO glad that the animation's done! I hope that audio guy finishes soooooooon) Err... sorry for sounding like a sissy girl before, I just can't believe that you're on Instructables! It's the only site that I eat, drink, and live for (other than yours, of course << ). Your instructable is pretty awesome... I've never seen a quality slingshot made from "scratch" before, and I'm pretty darn impressed! Awesome work, keep it up! (Btw, I'm "Muff" on blogger) P.S. How'd you find out about Instructables? If it's from my post on your blog then I'm pretty damn honored. If not, however you got here.... AWESOME! Hope to see many more Instructables from you in the future! -Josh

I was wondering the other day how I stumbled upon instructables and now that you mention it, I went back and looked at your comments on my blog and it WAS you :D Thanks dude this site is so my thing you wouldn't believe it. When I clicked on your link in the blog I saw all this awesome stuff come up and I got right to work on my slingshot. Waterlollies progress is screaming now.. it's a toboggan on hard ice :D
!! Wow!!!

I'm so honored... you have no clue ;DD

Yes, this site is REALLY addicting. I've spent hours and hours on Instructables without really noticing. The best thing about it, though, is that you never waste your time... it's always time well spent =)

Can't wait for waterlollies!


P.S. Perhaps post an Instructable on making flash videos... it seems like if anyone on this site should make one.... it's got to be you!

someone plese tell me what the crap a waterlollie someone plese tell me
By the way, I just created an "Adam Phillips Is The MAN!" group, and added this instructable to it. Is that alright? -Josh
chluaid (author)  T3h_Muffinator7 years ago
lol.. uh, I guess :P Now I feel pressure to populate it (in an effort to be The MAN).
Bah... Don't feel pressured! You're the man already... ;D
This Instructable is awesome . I want to build my own slingshot but i can't find a store which sells piano wire here in Germany. Can anyone help me ?
i made a sling shot and it shoots a big marble maybe 500 feet and goes like a hundred miles an hour. You can substitute a piano wire fore hair on a violin bow. its basically the same as piano wire because they are both from horses
wouldn`t a coat hanger work?
Have you tried both hardware stores and music stores? How about hobby shops? The wire doesn't have to be a specific diameter, just stiff enough to resist the pull of the bands. Also, wire is only one possible material to make the framework from.

Sweet!! Alot cheaper than the ones at Canaidian Tire!
well done again, man. i guess i'll make one of these nextime we have our piano tuned, or whatever.

isn't piano wire also like razor wire?
keags22087 years ago
can some one aanswer pandaboy292 please. i got wired coat handers not piano wire.would it be strong enough?
chluaid (author)  keags22087 years ago
Piano wire is high-tensile steel, or spring steel which means that it will flex and bend but always spring back into its shape. A coat hanger on the other hand, is ordinary soft wire. Sure if the wire is thick enough, it's harder to bend, but if you want real power in your slingshot you'll need strong rubber which would bend a coat hanger very soon, probably even with the first use. Beware when bending spring steel like piano wire. Sometimes it can snap if bent too sharply, and tiny shards of metal can fly off.

yeh, thanks though anyway.

I see that you can make a split shot with the BB's so I see.

Your sling shot inspired my sling-o-plane project in the launch it contest. While not exactly like yours it was a spinoff idea from yours. Good job.
