no joke this is the next thing I want from Mk1 its so clean looking

so my friend from my yoyo club @T4t3z0r88 said that you need to figure out somthing about the moment inertia when making Yoyos on CAD but what is that somthing?

You can read about what moment of inertia is here: Moment of inertia - Wikipedia
Most CAD packages include a way to set a material on a 3D body and estimate the mass and moment of inertia.
Having a high moment of inertia is one thing that can make a yoyo feel “powerful”, because it requires more torque to get the same rotational acceleration. It’s analogous to rim weight.
When designing a yoyo, it can be important to keep it in mind, just as you’d keep in mind the dimensions and overall mass.

thanks so much, I’m going to start designing a yoyo this weekend just for the fun of it and to learn the beginning stages of making a throw

so im downloading fusion 360 now but I know that you should not mess with the bearing seat, I was wondering if there was a file that I could download for the bearing seat, or if there’s some type of specs that y’all could give me for the bearing seat

You can derive the size of the bearing seat from known measurements of the bearing. Start there and then work towards more accurate and better guts as you approach prototyping time.

Welp. I downloaded fusion 360. Lets see if I can make anything with 0 cad experience

I’m going to download it some time today, though I have no idea on what im going to make lol

I’ve experimented with autodesk inventor I think.

So i am in the process of creating this with a lot of help from @MarkD and rob from airetic strings. I’ve been working hard the past week and I’m really proud I have something to show for it now! Let me know what you all think!

are you looking to design a signature throw?
Maybe eventually! This was my first crack at designing. I actually designed this with another shape/design in mind that was made for me by mark. The shape didnt come out with what I was aiming for, but I’m really happy with how it turned out. The specs for this design do reflect something that id want in a signature yoyo though.

I have a couple more ideas I’d like to play around with, so ill definitely be posting more once I polish this one up a bit more.

Anyone have any experience with a mini CNC lathe? What would the disadvantages be compared to a huge machine that weighs 6 tons? Searched around but couldn’t find any answers.
