You should definitely figure out how to dimension it.
Also increase the edge radius. 0.25mm is very sharp. I would go with at least 1.3mm.
53gms is light but if that’s what you want that’s fine.
You’ll want to figure out the MMOI in your CAD software.
I don’t know too much about designing in carbon fiber.
I’m not sure what you mean by using a brass insert and spacers and an axle sleeve. It sound interesting but I can’t quite picture it.
A straight V shape is certainly interesting. It’s not done these days but it was back in the day I believe.
All around this an interesting design. If you can get it made it would be very cool I think. Let me know if you have any more questions. I’ll try to help.
autocad doesn’t support material assignment unfortunately, so i find the volume using massprop and calculate it manually with the density of brass and carbon fiber to get the weight, so finding the mmoi would be really hard, most i could do to describe how powerful it is is the rim dimension and weight, OD 54mm and 20grams, as for the dimension parameter it’s already done, at least for the ring that’s all i need to give to the machinist
i have an idea to roughly estimate the mmoi, you’ve made so many yoyo designs would you mind changing the material density on some of them? carbon fiber have the density of 1.4gr/cm3 just change the aluminium body, my yoyo would weight at around 65grams if it was an aluminium bodied yoyo, you’ll get a rough estimates for the mmoi i think (ignoring the weight distribution ofc)
wouldn’t really chip, it’ll be like a plastic ding, especialy with the rim glued onto the body and that part is thick enough, so i doubt it’s going to chip, of course i’ll do a practical stress test with it once i made it
I’ve unlocked the power of material texture and rendering, this looked like the phenom because for the initial concept i thought about using a rim from sturm panzer eclipse ogre arousal sold in the orange japanese retail, i didn’t went with it because i can’t find the dimension of the rims
This is from the design notes for the Prohibition Excess (found via the wayback machine):
In order to keep the weight at the target of 65g it was necessary to trim as much excess (hehe) material from the profile and cup of the yoyo as possible. SS is able to be machined as thin as .5mm (as seen in the SS Koi and Bowl 303) but I worried that simply pushing the material to its limits would result in a less durable final product that had much higher b-grade rates. Instead, I chose to have slightly thicker walls and optimize the hub as much as possible to reduce center weight. This is not to say that the Excess much weight in the walls, as it is machined thin enough to have a weight distribution similar to that of a 7000 series aluminum yoyo.
Edit to add, the SS Koi write-up on the yoyofriends site includes:
The SS Koi also has a wall thickness of only 0.5mm to enhance the rim weight and power of the yoyo. Stainless steel is a very hard material so a wall of only 0.5mm thickness is very hard to manufacture. The machining process is very difficult due to the ease of causing vibrations and deformations. Fortunately, the final product has none of these issues.
I usually prefer rounder H shapes but the client wanted a V/H shape so I ended up with this sharp H shape. It works out since this shape is easier to pull off for its specs
I remember trying the OG Surveillance before, I liked it. Quite curious about the more recent Surveillance Max. Sounds more powerful & durable based on the description
I usually talk with people interested on a customized design but do not have the time to learn CAD. I also talk with people who already have their own companies & we get to discuss design philosophies which I still apply to this day. I offer sketching a design and/or rendering, usually
