Dynamic Balancer for Small Parts and Spindles

Worlds ugliest Franken-Balancer. A small experimental prototype made completely from chunks of scrap metal. Now replaced by a full size permanent dual axis balancer, this little Hobo is still used to balance batches of small parts because it is easy to set-up and knock down and does an excellent job on small parts and spindles. Because all of the 'guts' are exposed, it is perfect for demonstrating the basic theory of operation.

What a fantastic demonstration! Brilliant design!

There are a number of videos on YouTube that show the typical 'two target' dynamic balancer screens. They are all very similar so for those who are interested in how commercial balancing software presents the data visually, there is plenty of information available. However, I have not seen any videos that explain what the components are or how a dynamic balancer works. My short video does not duplicate the many that are already posted, but instead provides the underlying information one would actually need to understand the process. I discourage amateurs from building potentially dangerous machines. However, it becomes possible, proceeding at your own risk, to build a machine only if you know how it is supposed to work. And now you do.

That is very cool. I bet that most people wanting to know how it is built are more curious than serious about actually building one. Just watching yours makes me want to build one, but of course I never will (having no need).

Great explanation, and thanks for showing it!

You left the most important part of this whole system where do you know exactly where they put the weights?

[Heptode]

Excellent demonstration, and a clear explanation. Very interesting.

[therealspixycat]

Van you show the data accumulated from the accelerometer and angle sensor and how to make an interpretation?

[Sarah_Suantak]

This is a very cool things that I ever seen in my life. I think it's unique, simple nice and smart. Everyone who are in this way will like it because they all are would like me. I appreciate and thank to those who show me.

@
Simpsons36 On this balncer is that knurled knob just an adjustable stop?

[MrGGPRI]

For the hub just drill two set-screw ports at 180deg to each other and then do the final with the collar attached. This would likely reduce resonance points making final balancing less complicated.

Thanks, again great video.  I have been curious about the balancer since it was mentioned in one of the much earlier videos.

I was searching for this kind of example, now I am happy, can you make single cylinder 4 strock engine example ?

[pierresgarage]

Great demo and basics about balancing... ;)

[dronecy]

can ı use this for motorcycle wheel balancing?

[fahb]

This is with electronics, how they doing it in the past like 30's to 50's

[svin]

I was wondering if you could send me on a path to find the software you were talking about.

[Keith_Ward]

Interesting, I have not seen one of these before.  However, you jumped from running the device to a magically balanced part.  I am guessing that after running the software the mapped out-of-balance points are retrieved by manually turning by hand until they are straight up, down, etc, or on a pointer so you know where to drill/lighten?  Would it be possible to show the software screen(s) while running and how the end results are displayed?  How many accelerometers are used?  Two per axis (X, Y)?

[flavour]

I have a question, what is the resolution of your rotary encoder?  Thanks, Ron.

[svin]

Can I ask what you are using to to input all of your sensors to your computer?

[ShopperPlug]

we cant hear you, your mic is low in sound.

[nonetaken]

This just looks like static balancing. I don't see any ability here to do dynamic balancing.
