Can someone tell me if this design is viable? The hub is made of aluminum, and the body is plastic, press-fit onto the hub. Kind of inspired by the H5 Leaf, although I’ve never tried that yoyo myself. Thanks! ![hybrid hub 10.30](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/3/6/b/36b679c901447804db2098e893ce613b3fce2971.png) ---

This will probably fly apart. Ideally you have one metal part on one side of the plastic (the hub and bearing post) and one metal part on the other side of the plastic (the bearing spacer). The bearing post goes through the middle, and the screw pulls it together. ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/1/6/b/16b7b52087886ad80fbe7b365c9867a7b2f2c295.png) ---

Thanks, this is what I had thought. But from pictures of the H5 Leaf, it looks like the hub is just a single piece of aluminum, with the plastic sitting on top, so I thought I might try something similar. Does anybody own that yoyo and can confirm how it’s constructed? ---

I know it’s possible to make designs like that (iceberg has a single piece hub also), but not how you’ve drawn it. On the iceberg at least there’s all sorts of stuff going on internally that you can’t see without cutting it in half. ---

It looks to be a concave slitted section that holds the single piece hub in. It looks like it’s pressed through the inside of the cup and is kept in place by the retention groove ---

I would love to cast these for you if you rather try that. I’m actually working on casting a few right now and was looking for folks to help me R&D. My biggest issue so far is balancing and how to ensure I do it properly. ---

forged carbon fiber’s best properties is that you can make a solid 3d part straight from a mould, there’s absolutely no reason to add extra steps to complicate the process ---
