I dont really know, im kinda going for a SF feel and the cadence is made of 7068

here’s a responsive yoyo that I’ve been playing with in cad
width: 46mm
diameter: 54.5
wight: 46 (around 48 with guts)
metal: 6061

ok so I have a question about bi-metal rims, how tight should they be against the yoyo
A yoyo-specific machine shop knows how to create the correct interference fit, so your drawing only needs to have them touching along the same line. That line should be as long as you can manage though so it has a more solid fit.
A longer, more correct answer would require calculating the fit from an interference fit table. There’s some talk about that here: https://blog.misumiusa.com/shaft-hole-tolerances-for-clearance-interference-fits/
And here’s an example table for interference fits between steel parts: Class V Locational Interference Tolerance Chart for Holes and Bolts
The fit doesn’t need to be particularly strong because there isn’t much torsion between the ring and the aluminum body in a yoyo, like there would be in a power-transmitting shaft.

After reading through the ideal responsive yoyo thread, i decided to try and design my own metal responsive. As I have only played a couple modern metal responsives and own none, I decided to take inspiration from a couple different sources of yoyos that I enjoy that are close to this, as well as design cues from others. I wanted the shape to be reminiscent of a torrent or bassalope shape but in the form of a slimline. I tried to make the cup as smooth as possible leading up to a small center spike, having some inspiration from the edgeless there. Also played around with the response groove, tried to make it a flowable response, I think flowable is great and the size of the groove should be able to hold a lot of flowable for a long time. Lastly, for weight, I looked at the weight of the OD deepstate and tried to get my total weight around there. I threw in a C bearing because the knowledge for different sized bearing guts still alludes me, but I would probably try to make this a D bearing.
The specs are as follows:
54mm diameter
34mm width
7075 aluminum
4mm gap
10mm axle
51 grams

what type or bearing and what type of pads are for this design
dude read the post

oh I should have looked at the top lol
C bearing, flowable response.

Main thing I’d recommend is making the wall higher for stalls, and of course, shoot for A bearing with a narrower gap than usual. The shape and cup look great though!

Def need to figure out the bearing. Trying to design it to be good at what everyone wants as a modern responsive, but also so it can shred some longer combos as well if your technique is tight, which is why the wall is a bit lower, but I could probably make the wall a bit higher as well.

I think given it’s a ball bearing design you can get longer combos even with a higher wall if the user is skilled enough at keeping everything lined up.

I love the shape of this yoyo!

I made the wall about 3mm higher. could probably go a tad higher, but I think its fine now. Red side has the higher wall, blue side is the original side so you can compare. Same weight.
I think im gonna keep it with the higher wall, and maybe make another yoyo with the original shape that I had, its a very nice shape.
Edit: more pics, even sides this time with the higher wall, and a nice cup shot, because this cup is so dope

That’s not half bad @hobbygod. It’s pretty close. Can I suggest that you keep the inner walls no lower than 26mm, push a little more weight to the centre if possible and shave it down to under 50g. A 50g wood yoyo that feels perfect can feel like a real thumper in metal. The gap is a little worrisome too, I’d suggest more around the 3mm mark.

@hobbygod. Mostly this design looks good but the gap/bearing seat is wrong.
The bearing seat is too tall and is even above the wall of the yoyo resulting in what looks like a 5+mm gap thats wider than the bearing. I think you accidentally made the seat taller instead of lower for a smaller gap.

i didn’t even know you made this post! nicely done… i loved the thought process you spelled out in your design too. the influences 
. being this YOUR METAL yoyo, the design parameters and therefore tolerances, are significantly different then other materials. godspeed @hobbygod

question, are any of you producing these, or are you just designing? just wondering because, i dont CAD and even if i did i couldnt produce. i dont have the access to specific machines. just curious if you guys have access to machines.

Thanks for confirming a suspicion I had! I havent really played with the guts too much in other designs, so I definitely need to figure out the fix for that.
