Mark132 and Ricerocket

I am totally impressed and blown away by what you have done with yo-yo's. I never was much good with a yo-yo but then after seeing what you guys make  I wonder if what I was using could even be called a yo-yo. Thanks very much for showing them to us on MadModder. I am sure a few of the chaps will pick up a few tips from you to try on their own.  :D :D

Cheers  :beer:

Ya, double what Don said.

I had no idea there is such a diversity of Yo-yo's. I'm very impressed.

Glad both you guys became members and shared. Thank you very much.

Great job guys!!! I've been wanting to make a few Yoyo's. I drew up a couple a year or so ago. I just haven't had any time to make them yet. I wanted to make some out of acrylic rod. But haven't found any big enough yet. Thanks for sharing.

A Gismo ??? If it has a flywheel or spins and is made with small parts. I'll take one! If it makes noise, moves, or requires frequent oiling and dusting it's a better deal yet. It's especially right if its shiny and bright; but if it's dirty and dull it wont mater at all...

Very fine stuff... both of you do great work. I like to think of this site as modding culture period. Doesn't matter what it is... but how and why. I see the art in the mod itself.

A friend makes fantastic production yo-yos by hand out of acryllic.

A new project i've been finishing.
****WARNING LOTS OF PICS****

A boring 20$ plastic Duncan yo-yo (Freehand Zero)


boring out and facing the hub area



New Hubs!



Sizing to fit


Very tightly press fit


Tapped M4-.7 and interior bearing post cleared


Exterior bearing post cut.


"armor" inlay area taper recessed on compound slide



Exterior bearing post ("hubstack") cut from acryllic pen blank.



weightrim area cut

weight ring being cut to size


Weight ring attached via o-ring in a groove. slips on and off easily.


yo-yo half

yo-yo assembled


Interior bearing seat cut and silicone response groove cut and filled with silicone.

I absolutely marvel at what you lads get up to.

How do you know what to do? Is it all guesswork, or are you following a proven formula that gives you what you want, or just a combination of both?

I really do admire your work, not only on the machining side of things, but how you come up with new ideas and put them into practise.  :bow: :bow:

It's like taking a lump of tough old meat and turning it into a gourmet meal.

If you don't try it, you will never know if you can do it.

Thanks for all the kind words.
Just a bit more background and "research" on me.

i graduated from college in December with a B.S. in Mathematics. My senior research paper was about yo-yo tricks.
I have lots of information about modern tricks in it and a couple formulas that describe them.
http://www.yoyonashville.com/Seniorproject.pdf


Congratulations on your enjoyable thesis using Category/ Functors and Freyd's Allegories. I was laughed
at in 1959 when I predicted that Homotopy Theory, Category, and Topos would actually have practical
applications. ( e.g., Algebraic Theory of Machines, Foundation of Computer Science, Cognition, etc. ).

Thanks to you I can now say that they were  indeed the YO-YOs!   :)

Much success to you and best wishes.

Does anybody have a drawing of the hub stack with bearings? I really would like to build a couple of yo-yo's for Christmas presents.

Thanks

This is the basic quarter profile of a modern yo-yo. Most yo-yos are some variation of this profile. This one does not have the independent spinning side stacks.
the side "hubstacks" usually look like this.

the bearing is held by an o-ring in a groove. the ones pictured are add on parts for plastic yo-yos that use a hex bolt for an axle. Most aluminum yo-yos have the posts machined during production as a permanent fixture.
here is a tutorial on hubstack assembly.

The functionality of having hubstacks.


Hubstacks are not  absolutely necessary to make a yo-yo. they are a neat new feature that lets you grab your yo-yo while it spins. online yo-yo stores sell hubstack parts: the orings, bearing and plastic gripper.
here:http://shop.yoyoexpert.com/category/10/Hub-Stacks

I'll see if I can get an actual cad drawing of the hubs. Hope this helps.

just found this vid. My lathe in action being used by team japan in the iron mod contest at the world yo-yo contest

This is amazing stuff, thanks for sharing! Who knew there was so much technology & clever design in yo-yos!

If you wanted to make a yo-yo like the last one I used, you'd have to mount the two halves the other way around, and use a solid steel axle!

Kind of like this one:

Cheers!

Here is a job I did for a local kid. Took an oldish (1980s) Duncan Wheel (fixed steel axle). and modernized it to take an unresponsive large bearing and recessed silicone response.


tapped a 5-16 threaded insert in the caps for a 6-32 axle, then turned down to fit in the original axle hole.


The inner gap is faced flat.



Cut and drilled a stepped bearing seat spacer.

The spacer parted and placed near where it will live later.


the set of spacers, they look different but I think one just wasn't deburred from drilling yet.

The bearing sitting in the spacers

compared to a stock duncan bearing and stock spacer setup(left)
.
The spacer housing and response groove cut into the face of the yo-yo.


the spacer installed.

+bearing

both spacers + axle, ready for silicone response.



using a plastic spoon to put a concave recess in the silicone for best response.


should have gotten a final result playing photo. May take one later and post.

got it:
