The machinists have a lot of software tools at their disposal to convert those lines into toolpaths for the lathe, so I wouldn’t worry about them. I use them to a smaller extent under the rims of the Exia and Diffraction, both turned out great aesthetically, and no complaints from the machine shop.
If you want some nice generic D-bearing pad size to use, FD has one that is 19mm outer diameter, 13mm inner diameter, 1.15 mm deep.
You can duplicate the 7075 material and save a copy called 7068, you’ll need to update the density to 2.8 g/cc though.
Thank you very much. I love the cuts on the inside of the exia. I will have to work out the 7068 duplication. I based the bearing guts from the freshly dirty bearing guts. I can imagine it all needs refinement.
Thanks again
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.
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…
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!!
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:
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.
