How to get constant force spring for your project/sculpture
This is a video showing how I get the spring for my kinetic sculpture(th-cam.com/video/zFrTlWlbVjI/w-d-xo.html) from cheap measuring tap(5m).
Notice that the spring can be very sharp, handle with care and wear gloves.
It is more than likely that you will need to design your own axle/holder for the spring you get. This is just an example of how I make mine.

kinetic sculpture - how it works
มุมมอง 27K3 ปีที่แล้ว
This is a quick demonstration showing functions of key components for my first kinetic sculpture(th-cam.com/video/zFrTlWlbVjI/w-d-xo.html).
DIY 3D printed kinetic sculpture powered by spring
มุมมอง 40K3 ปีที่แล้ว
This my first kinetic sculpture. It is designed in SOLIDWORKS and 3D printed with PLA. The design is inspired by David C. Roy. The longest run with full wound is 108 minutes.

After winding it all up, how long is the runtime? I'm just curious.
Fake stuff. Tape spring doesn't work like this. I will show you, how it works.
赞，老伙计。一般的卷尺都是power spring吗？然后视频中等于是把外卷绕改制成了constant force spring应用了吗？另外我想问问，有没有恒力卷尺，而不是power sping卷尺或者说priral spring卷尺而直接使用恒力弹簧的卷尺商品？
Incrivelmente perfeito!
A real piece of art , sir . I am not trying to steal your hard work but I am beginning to try to stimulate my own sculpture in solidworks motion the problem is to make a rotating body lose angular velocity due to tangent friction and shear stress ( done by air on the mechanism ) I cant figure a way to stimulate those parameters so can you tell me just how did you ( at 0.57 ) this motion where the spinning body changes it rotation direction and how to stimulate the loss in kinetic energy in the sculpture .
Unfortunately, I don't have my file with me after switching to a new PC. Yet, I can vaguely recall that I added friction to the surface between the ball bearing and the rod. I did not take any air friction into account (since I only wanted a visual effect). Finally, I added gravity to the motion model. Just play around with the numbers to achieve the visual effect you desire. I tried to simulate the actual model with real data (weight, density, coefficient of friction, gravity, etc.), but I could not get it to work properly.
@@weilianghsu5647 well I done it yesterday , and when i throw logic out of window and started playing with numbers I achieved the free spinning motion , btw last question when the body spin in the opposite direction and the lockers touch it nd make it moves the other way , what mate did u use to stimulate them being in contact for 3 sec ?
SaludosdesdeMonterrey Nuevo Leon Mexico muy buen trabajo .cuanto dejas entre ruda yrueda de picos
Ha this is exactly what I did! I came to this video to see if there was a better "right" way:)
Amazing 😍, Improvisation of measuring tape spring for powering the mechanism is really fantastic. Can you tell which software did you use for simulations?
SOLIDWORKS Motion for simulations
Don’t do this, never roll a constant force spring opposite of it’s natural curvature
Could you explain why please? I have tried to search for a reason why it is dangerous but to no avail
That’s not what happened.
could you please supply the stl for the spring holder? it would be greatly appreciated
忘了說明：我不會用3d列印，只會用線鋸機！謝謝您！
Hsu 先生您好：最近都在看有關您po的影片。不管是恆力彈簧的製作，或是kinetic sculpture 的設計，都很讓人覺得很有趣想試一試！不知您是否可以告知網路上哪裡可以找到相關的參考資料或是設計圖呢？謝謝您！
Very nice explan
I tried to make the similar kinetic sculpture. As it didnt run that smoothly, so I used electric motor to power sculpture instead of spiral spring. Please check this out. @ I will welcome all kinds of suggestions.
To wind the spring you have to remove the front wheel each time?
It's possible to wind the spring with front wheel on. But you will have to push on the wing of back wheel which is likely to break overtime.
Hah! I've just learned about the existence of constant force springs and that they work by "unrolling a coil of spring steel", and I thought "that sounds a lot like a measuring tape" and here we are :D
Thanks for the great idea. Here was a 5 m tape. I saw 7.5 and 10 m tapes in stores. Will a spring from a longer tape drive the kinetic sculpture much longer?
I had not tried the longer ones, but I would assume they will store more energy (the springs might to be wider/thicker).
@@weilianghsu5647 Approx. The one I bought after dismantling is 5.5 m long, 21.5 mm wide and 0.15 mm deep. I am slowly completing the printed elements. Greetings.
Inspiring, thank you. Getting my first printer soon.
interesting, thank you
спасибо за науку 😉😄
Awesome. Where is a good source for all the hardware required?

CLICK BAIT
make it by your own two hands..................
Thank you!!!
STL file please.
can you share the SolidWorks model?
Hui sir plz full machinical tutorial video
Love this video - I have been collecting tape measures to remove the constant force spring but was not sure how to apply this to my project... Now I know the way forward. Thankyou so so much.
♥.♥ Nice Coaxial Circles.
This is inspiring! I want to build something similar.
Can i have detail step by step installation vedio arun.gohiil27@gmail.com
Do you sell it man? How can I buy it? Thanks.
You know how to teach. Thank you for showing the right thing the right way
Hi, is it possible to get design files for 3d print?
Which CAD did you use?
I used Solidworks.
Could you share the SOLIDWORKS files including the assembly please
Thank you so much . I want to try and make something soon . Your videos are so helpful.
How can i make this??
If you own a 3D printer, you can find the files and instruction here: www.thingiverse.com/thing:4768206
Prize
Good job,I wish that you could make videos series of kinetic sculpture ....we want all details...step by step...... thanks for your efforts....good luck.
Would you consider selling the 3D printed part for this?
how does the back wheel start spinning counter clockwise to trigger the spring again?
Its center of mass is slightly off center for the back wheel. If you look closely you can see on one of the wings there is a small exposed screw and nut. They are used to balance/adjust center of mass.
@@weilianghsu5647 oh now I see! Brilliant!
@@weilianghsu5647 I'll print a pair of the wings with more infill to get a cleaner look and not need the screw+nut
@@BaristaPablo Yes, that should work too. My original plan was to glue the weight/ magnet to the back of the wing. But at the end I got lazy and just left it as it was hoping no one will notice. Great job on asking about the counter clockwise rotation! That's one part of the instruction I need to update soon.
thank you i have a few projects I printed that needs this
I am glad that it could help!
This is awesome. And ingenious use of the tape measure spring.
Thank you, they are easier to obtain and relatively cheap. I recently uploaded a video as an example of how to retrieve the spring. th-cam.com/video/FElXXzynPnI/w-d-xo.html
@@weilianghsu5647 Rad thanks! I'll check it out for sure.
Can you point a link to that exact tape measure?
Unfortunally I cannot find the exact one online. I just grabbed the cheapest one I can get from a local store.
❤️ Beautiful sir ❤️ where I can get this sculpture please inform to me sir ❤️
It is a DIY project for people who own 3D printers where all the necessary tools and material are listed here: www.thingiverse.com/thing:4768206
thanks for making these videos. My kinectic sculpture is on hold at the moment. been busy with a few other things, . I have a few issues which are hardware related, the ID of the cheap bearings I iver are slightly oversized for 8mm rod, so they add some slop into the mechanism, which causes some issues, will get it all sorted though
Okay, let me know if you have any issue regarding the design.
Creative mind.. thanks for the video
I had trouble finding constant force spring myself. The ones from tape measures are not the best quality springs in the world, but they sure do the work.
@@weilianghsu5647 yes I found that there is a thicker version of measuring tape. It has pretty decent spring.
@@rameshvk4147 Cool, just be very careful when extracting the spring. It releases tons of energy when removing from its original housing.
Plz share price ...
Most parts are 3D printed, and I have shared all the 3D files needed to build it. Please visit: www.thingiverse.com/thing:4768206
