I made this today. wanted to try and make a yoyo with the specs ive been wanting (54x46) but with 5a in mind. 65 grams, 4.35 gap (because of that gap thread I wantes to try one this size haha). 7075 and a 12mm axle to keep it durable. Has a medium wall but i dig it. Anybody have any name suggestions?

And they are on their way over to YYE but might take a while because of covid delays.

I must say, your hub design is excellent.
Very distinctive and functional.
Short axles are a downside though. But long bearing seats help get those valuable threads back.

Thank you.
I imagine you went through a process like that with the Abyss, to keep the fingerspin zone optimal. It looks superb!

Yes, indeed.
The new run will feature a tweak to the seats though. Because they need to be longer than normal to offer more threads, the bearings are more difficult to remove. Thus the news seats will be composite: conical at the end with a straight part the length of a traditional seat. Best of both worlds.

I did this on the Umbra - worked pretty well, though the flat part was still a bit long, about 1.1mm. Haven’t had a bearing get stuck but they sometimes take a bit of work.
Definitely a good idea if you’re extending the posts.

Some stuff I’ve been working on over the past couple of days : ) First shot at Fusion360, or actually at designing a throw at all – so I’d love any feedback, responses and criticism.
Current specs are:
Diameter: 55.7mm
Width: 48.2mm (gap width 4.4mm)
Weight: 63.96g
Material: 7065 aluminium

Thank you for sharing this!
That’s an awful lot of control points there - you could probably redraw some of those sections as 1-2 circular arcs and have it come out better.
The circle on the hub is a cool idea.
The response bump looks really flat, to me. I feel like the string would catch on it just a bit longer than you’d like it to.
The IGR could be moved closer to the rim face, which would improve machinability a bit, and help keep some of the rim weight closer to the string plane instead of right at the edge.

Thanks for the feedback Mark!
On the note of control points – I remember some resources warning against using splines and control points. I was wondering what the rationale is for that? Will definitely look into using circular arcs to replace these though! If it makes these lines cleaner : )
I’ll try touching up on the response bump and IGR and see if I can do something smoother! Thanks again : )
Just curious, based on your experience with designing yoyos – how would you imagine a design like this playing?

Most CNC lathes can not use splines as tool paths. This was mentioned in one of Lerner’s vids. You can always approximate a similar curve with arcs and lines.
I haven’t really played such a wide organic, but this would have a pretty solid amount of power on the throw.
How do you want it to play?

OK got it! Toying with it right now.
I definitely was looking for some oomph (therefore the flat hub, thinner walls, weighted rims) but wanted to retain some agility and bounce – kind of like how the Akita plays – so I kept the total weight slightly lower at 63.9g. Was also trying for a “hollow body” feel that the Ti Bowl and 420 has. Kind of a middle ground in having some power without it feeling like a dead rock.
Made some changes to the rim, profile and response step!
Currrent specs are:
Diameter 56mm
Overall Width 49.4mm
Weight 64g
Did some work on the response step, kind of like how this turned out.
Some cup details.

made a new throw today. 53x40. 4mm or 4.2mm gap i dont remember. 63-64ish grams. Inspired by old school yoyos, kinda like a mini organic genesis type vibe with it.

I think the step off of the response is too close to a 100% flat angle here. The edge looks a bit sharp, too. The rest of the shape is looking pretty nice!
