- Is it possible to make a catapult that can launch a boomerang that'll always come back?
For some reason I've always wanted to try this, and now I've found out that ideas aren't always as easy as they may seem!

**tom makes funny sound**
Now that was consistent
Thanks now I can’t unnotice this
Klunkhhhhhhh
With headphones on it sounds like he's beatboxing.

"ugh"
Tom Stanton and Real Engineering less then an hour apart? Today is my lucky day!
Can't believe you've betrayed the trebuchet master race
to be fair, he is attempting to create a catapult thats only purpose is to destroy itself.
@@Phirdude40k so a more useless catapult?
Useless, swithces itself off
More useless, destroys itself
Most useless, destroys itself and the surroundings
A nuke can be called... "so its a most useless machine?"
@@Phirdude40k
Quite a clever little plan if you ask me.
@@Project_VideoGame well not if you want to make a bomb :
A bomb that doesn't destroy itself is more useless
A bomb that doesn't destry it's surrounding it's most useless
The next phase of this project is to put some servos and instrumentation on the boomerang so that it will be able to control its own flight path and steer itself home. ;-) Also, the long form videos are a nice change. The extra touches done in editing are cool.
Haha 21st century boomerang ;-) Great thanks mate!
I was about to type this identical comment, then saw this one below ... I need to become a patreon :D
I wonder whether you could do it using a single servo. Like how a monospinner can move in 3d space with only 1 propellor.
@@charleslambert3368 These already exist! Can't remember who made the first one but Lockheed Martin followed up on it.
Before you try to control it maybe try to grasb the aerodynamics of it and what would you need to control, its not as easy as it might seem. ua-cam.com/video/T7LAnT2r_vo/v-deo.html
Love how you have CNC and a 3D printer but use 2 wicker garden chairs as a sawhorse 😂 Another entertaining and intersting video as always Tom!
I recommend 3D printing a vacuum attachment for your CNC router. Instead of chasing the bit around with the vacuum, you'd just have to flip a switch.
i was thinking the same thing lol
Same
Great video Tom.
One difference I was noticing between you throwing of the boomerang and the machine launcher was that you was stood throwing the boomerang and the launcher was sat on the floor meaning the launch had the height already when yourself was throwing it.
Brilliant stuff!
I'm a blacksmith/metal worker, if you wanna do something metal based collaboration let me know! I build and fly foam planes but nothing fancy, also Hertfordshire based.
Cheers,
Joe.
@dogboy1953 i wonder if that would actually work if the metal used was light enough...
@@Sharpless2 it doesn't matter what material is used for as long as it is light enough
Hmm, a magnesium boomerang? That’d be light and deadly...
Should I put this in r/cursed comments?😀🔪

Cool explanation on 'gyroscopic-procession' and why Boomerang curves. Didn't know that!
that's a fun project :D
g
No its not honestly :D
That sums up all of his projects!
Hi Tom.... Thanks for making me SMILE! Truly a wonderful effort and outcome. Plus, after all that 'lounging' on the electric bike, you got in some exercise! FWIW, I'll be watching this again with my 8 year old grandson. He's at that stage where he's wondering how -and why- things work the way they do. You should know that you're a good influence on today's upcoming youth! Thanks again.
Glad to entertain you and hopefully be of influence to your grandson!! Thanks!
I swear I mentioned in a previous video that you should make a boomerang launcher or use the trebuchet to launch a boomerang
Ah yes, I believe it was mentioned on one of my trebuchet videos! Thanks for the suggestion!
But the catapult is so inferior to the trebuchet...
No need. It isn't a 90 kg boomerang...
Why not?
And he doesn't want to launch it 300m but 0m...
A trebuchet could work. It’s lever wound need to be strong enough to impact something at near vertical.
It is totally easier to scale up to rediculous sized boomerang with trebuchet. No motor drone for quick recon, anyone?
Great project, dude. Considering all the variables, some I just thought about and you didn't even listed... That's pretty darn good result!
Thanks dude!!
Great video!
Next time put some contrast colour at the bumerang so they can be seen better on video. Would be great. Like with the trebuchet projectiles.
I love how you go from a fancy "Laser guided" CNC machine to 2 outdoor chairs for woodworking. Now I can relate to that type of woodworking haha
Who said only idiots repeat the same thing over and over expecting different results, they were never introduced to an automatic boomerang launcher! Love your channel!
Now where did I put my boomerang, Tom thought... Suddenly, it came to him!
cringe
Did you say Dad Joke or Bad Joke?
Suddenly it hit him
Exit
I love your elegant and simple release concept. Very nice! You definitely could have just tried a few (hundred) more times and got one throw to hit the launcher, then just showed THAT one, but I LOVE that you show the whole process, and how you worked through it, and (probably) most of your attempts. Definitely NOT a failure, BECAUSE YOU LEARNED FROM IT.
Way to go!
as far as i know boomerangs actually need the wind to really come back to the thrower.. and maybe your catapult is just a little low? after all humans throw the boomerangs from shoulderheight.. and a little downwards too.. so they have more clearance before they would hit the ground.. interesting project, though! :-)
Most boomerang only need a little bit of wind. Most of my boomerangs fly much better with no wind at all.
No; no wind is necessary. It's entirely due to the aerodynamic and gyroscopic properties of a properly built and thrown boomerang.
I often had boometangs comming in ver flat , below the elevation of throwing. Funnily it's quite obvious, but Tom had 16 variables he would identify instead. Would like to see a sinhle launch from an eye height.
I do believe i have a proper boomerang for ya. Love the invention my friend. Wish you were my neighbor, i could at least hold the camera for ya lol. Every time it made a full circle and landed in front of you i would still call it a win. The launcher did it's job. That boomerang needed a little bit of breeze to push it back just a bit. I don't think hitting the ground made it fly any different, i think it was simply the change in wind direction. This test would have gone so much better in a huge arena with dead air. I know, not practical or feasible. I've thrown 1000's of times and i only go out first thing in the morning or just before dark when the breeze is at it's lightest.
Great video :)
Please if you feel the need to - do talk about airfoils for ages. I'd watch that.
you can also add a coin on the tip of the boomerang so it spins longer. I had to do that to my 3d printed boomerang
CNC router for flats, two wicker chairs and a hand saw for dimensional. Best of both worlds.
I thought that was funny. "He has a CNC machine, but not a mitre saw?" :P
#Priorities.
6:30 "about six and a half minutes into this video..." that was either a good guess, or well edited 🤔😋
I like that the engineer is happy when something is consistent
The first two and a half minutes of this is tom playing lonely catch
Throwing boomerangs can be a team sport as well, though
Sweet vid it was like watching Mike Boyd meets Smarter Everyday meets Tom Stanton!
Well done. As a long time boomerang thrower and erstwhile manufacturer (Rangs Boomerangs Australia) I commend your inventiveness and persistence. The release method approaches actual genius. I'll be sharing this presentation with my boomerang buddies.
I was sat here almost shouting at my TV "NAIL THE BLOODY LEGS ON!" lol. It'd certainly help your consistency.
Nice video! Long format FTW! Worth mentioning that it's very important that you show the failures, that is the most teaching part! The successful part of your videos are more for our, and most probably yours, enjoyment, but the teaching part is on the failures and your workarounds! Love your videos!
Finally, your explanation was better than any other (how boomerang works) search result I got
I throw boomerangs for sport and collecting, and I'm amazed that you made this work. I had my doubts, but by god, even my hobby will be taken over by robots. Excellent job!
I have so much new respect for Sokka. His boomerang always came back. And that must've taken lots of fictional skill.
Awesome Video! Awesome Build!
I too have thought about possible designs for a boomerang thrower. You did great. That cup of tea after all of those throws gave me a good laugh
Tom, if it means making a whole new sequel to every video you make of you talking about the physics and maths behind the video project, then so be it. I'm sure many people would appreciate it. I sure know I would...
If it circles behind you more out of wind to the right of wind. Circles in front of you too much out of the wind. Aim more left.
Well that's an A+ for persistence!
Great video!!
Tank you for teaching physic this way .
It is fun to watch and you learn something .
Greetings from Germany .
Not a failure. Those shots of the boomerang describing lazy, gravity-defying curves are just beautiful.
I was thinking that your axle could of been a retractable pin powered by an actuator, however ever your solution is even better!
It's harder to design something simple than complex, I love that notion
I admire your perseverance and I love the work you put into editing! The catapult-timed-to-music bit was cool!
Love the idea. But the boomerang can swing a little bit on the hook so that the angle of attack can be different every time.
Maybe place a board (or 2 boards) nex to the boomerang so it will stay in the same plane every lanch
Great job Tom. I love your persistence and thorough explanation of your thought process. Keep it up. Cheers from the U.S.
You're the only person I wholly respect using a bosch mini drill
Best explanation on how a boomerang works ever. Good work!
That effort for this little experiment is very impressive. Great video. Thank you.
We have to appreciate that he stood up, walked to the boomerang, picked it up, walked back, put it in, make sure the camera is set, sit down, lunch x 89 times. Thats a lot!!
Love this format, and as an Australian, love this project even more!
"I've built these things to see if I can get them to work..." -every engineer ever
This kid's joy is infectious. Go Tom go, love from LA.
Your excitement when you caught it for the first time made me want to go out and buy a boomerang right now
As a boomerang thrower I appreciate your job. What a very fun project , congratulations !!!
Fascinating as always! Thanks for another excellent episode.
Tom Stanton,the man that simplifies !! Totally love this video even though it failed
I never know what you’re talking about but I can’t stop watching
UA-cam recommendations got it right and gave me this vid today! Amazing! Didn’t know how a boomerang worked!
I love a simple solution to an issue. My first thought was a timed release mechanism using an actuated axle or something but I think it would be very difficult to time it. Your solution guarantees it releases with the right pivot. Brilliant
I like what you did with syncing the snaps in the song with the catapult hitting the tape stopper
Your explanation of boomerang is great!
I love you Engineering + making combo
“That was like...... I need a cup of tea!”
Well, it’s confirmed.... Tom is NOT from Louisianna.
I think sometimes you get so focused on your goals you don't realise how amazing what you have achieved is.
Tom: how about a magnus effect aircraft? Might be your cup of tea.
[circular(spin)/ lineer velocity] ratio is also important. if you would make that hole closer to the elbow(center), more kinetic energy would go to circular and less to lineer motion. That something you could try. That boomerang you can throw it with the lift arm, dingle arm or even elbow. And elbow you can make more spin.
Excellent. The pursuit of knowledge.
Hi Tom, I'm a boomerang-thrower myself (member of the German National Team) and I'm pretty impressed with your construction of a boomerang-launcher. But I'm also happy to see that you like to throw and catch boomerangs without any mechanical construction. Do you know that there is a British Boomerang society, which organizes tournaments and building-workshops. They also have throwers that like to experiment with boomerangs as well (and build a vertical wind-tunnel for example). Look the British Boomerang Society up on the Internet. I'm hoping to see you soon on a boomerang-tournament to exchange some crazy ideas about boomerangs with you ;)
That was a really interesting project. It would be nice to hear about the design and options of the boomerang itself.
Great job and well done!
The go-to tuning I see members of U.S. Boomerang Association (USBA) doing is taping a coin-size weight to the wing-tips. Sometimes amateurs use an airfoil that makes too much lift. I like when a light Boom spin slows down at the end and hoovers down for capture.
Thanks Tom, great video.
This new format is awesome!
Nice to see the A350 on approach and the climbing bird in the sky in your second throw shot, I really miss the time in my life when I could spend days building something completely useless just to see if I could, good on ya.
Brilliant project and video
I did a lot with boomerangs 50 years ago, great fun. I always pushed the daylight a bit too much, and then the game became dangerous! I am really enjoying your experiments, and I find I have touched on quite a few of the subjects which just makes it all more interesting. Keep it up :)
Liked this format allot.
Good job so far...but for one...make that thing stable not rocking when you launch. Second, make the arm just a bit longer and third, the stopping blade stalls as it slows down and generates drag which makes the other wing come up and around by means of inertia of the second blade which you should balance angainst the drag by making the tips of the blades a little heavier in your case (it just seemed that your boomerang was not spinning as fast as it should). I think you can see what I'm pointing at.
Ps. It will give more stability and a longer flight time, though it will also influence the shape of the flight.
I appreciate your hard work bro.
Keep going, best of luck
Some suggestions after reading the comments: Put the launcher on an elevated platform and when proper release angles are established, fix it securely. Play with the location of the pivot pin to achieve faster rotation if possible. Use a ready-made plastic boomerang. There are a few decent two-blade plastic booms made. Lastly read up on tuning boomerangs for better flights. The light plastic ones respond very well to tuning although they won't hold it for long. I have no doubt that it is doable.
I can just about build a paper plane but your various and imaginative experiments are compulsive to watch. You must have one hell of a lot of spare time.
your diligence is impressive.
Awesome project, keep up the great projects. I am just loving the fact u hit the power lines twice. I can see it on local news now. Local engineer launches boomerang into power lines with home made catapult, community loses power.....lol
Dude thanks for the quick breakdown of gyroscopic precession!!
If you rigidity mount your catapult you should get consistent results. If you make that mount adjustable you can fine tune. I always like your videos keep up the great work!
nice informative vid Tom
I do like the longer all in one video projects!
absolutely enjoyed this video.. big thumbs up brother
When I was a kid growing up in Australia in the 70s there were a lot of good boomerang throwers around. It was a bit of a thing back then to practice - I guess it was our version of frisbee. I was pretty good at it myself.
I reckon one of the problems with your machine launcher is that it is too close to the ground. When you throw a boomerang you are throwing it from about 6ft high and you launch it in a bit of a downward motion; the aerodynamic lift then kcks in and makes a better arc. Maybe you could lift your machine up off the ground and get it to release a little later.
I love how the clouds walk forward under the launch sequences ;)
Lol brilliant Video Tom 👍😆
I would love to hear an entire video about the fancy shape of your homemade boomerang and the airfoil!
Trebuchet. Boomerang. Fuse together. Hospitalize self for glorious footage. I vote for this plan (hell I'd do it... I've done dumber things for worse reasons).
Hey Tom! Great work as always. The fact that you achieved a couple of launches that ended up within the 2 mtr catch zone is really good.
Please consider that you are not imparting a twist upon release as you would with a human wrist launch. With the catapult it is quite linear.
I’m very impressed with your release method.
The biggest advance for you would be a base to hold the catapult at a steady angle.
If the release is consistent then the next variable is variations in wind and turbulence.
Look for a bigger field, with nothing up wind of you to ensure clean laminar air flow. Those trees in the picture would have given turbulence. The smaller the flying object and slower the air speed then the more it will feel and be effected by, the turbulence. Of cause some windy days are more gusty than others too.
Excellent observation. My lifelong kite obsession taught me how disruptive distant upwind obstacles can be to getting a kite to launch.
Another unnecessary variable I see is the ground level launch. There is an abrupt gradient of windspeed from near zero at ground level. You can see it by blowing bubbles at various heights in various strength winds, preferably in wide open spaces. Watching the relatively slow progress of dried dead leaves along the ground is evidence as well.
The plane going across the sky after 1 min looked like CGI haha
Followed for a long time. You are getting VERY good at this! (both video and engineering). Best Regards, fellow engineer.
As a uni aerospace engineering student your videos are fascinating
when i used to throw one when i was little, I would be about 100 feet back in my yard and chuck it directly at the right corner of the house. It would lift before hitting the house, go left, and come right back to me every time. It was probably heavier than that one, and was a true boomerang shape. Now even though I could bring it right back, it was painful to catch! Also I'll note that the secret to a proper consistent boomerang through is a hard flick of the wrist, so it is no surprise you had issues with the catapult. You need the rotational force to be enough to carry the thing back to you
Sit down, get up, chase the boomerang. Sit down, get up, chase the boomerang. This sounds like a great workout tool.
