I really like the cuts inside, looks like a cyclone. Bet that would catch the light in some incredible way.
That’s a truly amazing effort there. I gave up on the CAD for the moment. I’m into my lighter/heavier yos at the mo so I’d throw this one quite happily.

Thank you. Still have lots of refinement to do on this but I’ll keep posting its progression. I still have to figure out the gap width and make sure the guts are right. I like the idea of having a shiny kind of finish to show off the cups pattern.

All those cuts in the cup are awesome and would prolly feel neat on a fingerspin! Great concept!

Thank you
When I see something like this, I can see in the future a new yoyo company, which is amazing, but at the same time I wonder… why did you say 7075 Alluminum and not going for the money pot of Titanium?
Is it that hard to machine titanium? Probably it is… I’ll educate myself in this sense, perhaps it is a question without any reason…
Btw, gorgeus project.
It’s expensive to prototype and manufacture titanium yoyos. Not the best choice for a first yoyo design.

Yeah, I reckon that, was reading some “google” information and found this:
That will answer a lot, but thanks for the feedback.
Thank you very much for the kind words.
Yep, you don’t need to worry about changing the other stuff for yoyo design
Thanks
Done a couple of changes. Rounded out the rim section and push a little more weight to the rims.
Also added a couple of cuts to the outer shell near bearing guts.
My basic laptop is struggling with the cad program and decided to crash before I could get a copy of the new cross section!!

That cup is stellar with all those cuts!

This is a fascinating cup! Very specular.
If you don’t mind some feedback - the rim is very flat looking and might look better with a either a gentle arc over the whole rim, or have it sloped a bit more towards the gap area.
If you look at something like the Markmont Classic:
The rims feel quite flat, but there’s a curvature to them that keeps it looking almost bouncy?

Thanks Mark I’ll have a play with the design. I suppose I was thinking of comfort in the hand when I made the section flat.
Do you know if they have a d size bearing on the mac master section within fusion? I couldn’t find when I looked but may just mock up one as a separate component.
Thank you for your advised I really value it as this cad stuff is all pretty new to me .
Search for bearings, metric, shaft 5mm, housing 11mm, width 5mm. The specific part they have is a rubber-shielded one but it has the same dimensions as an unresponsive flat D bearing.
Learning the CAD tools better. Hybrid pom/steel with cutouts. 59 grams and probably needs a lot of work still. Really generic V shape with 56x43mm dimensions.
Same yoyo but with transparent polycarbonate as the body material. Hard to see on a computer.

Thanks Mark.
That looks amazing.

I believe pic 3 is the copied.
Still, amazing job m8!
Also, just wondering, what material should I use to prototype my yoyo?
Titanium is like 30 USD for a pound so it might not cost as much.
The process of making it tho might make the price kick the can so…
Looking for a cheap, but sturdy material sort of like the replay or something
