I designed a W shaped MR85-W4 yoyo. I didn’t want this one to use the standard RBC pads, but a smaller custom size. Problem is, to do that requires a minnimun 5000 piece order. To get around that, I designed this one to use a standard O ring size that is used in taps (fawcetts). Cheap, plentiful and very easily purchased at hardware stores. ![1000008592](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/7/5/a/75adc187123d934a08eeea2f81d465adb60ca8c7.jpeg) ![1000008591](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/e/b/f/ebf0244d34c3be713a2df97fa5453e9735a13b95.jpeg) ![1000008590](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/7/e/1/7e17ad0ce58f21a0f16b7bbb81e67ae5d94a73d2.jpeg) ---

@ yocolas There are a few problems with forged carbon: -Forged carbon is not a homogenius material so you have to balace the yoyo proper -Small parts are difficult so get out of the mold. Especially the part between the response pad and the ball bearing -if you print the mold it is often not precice enough to fit the weight rings so you have to overwork the body I have tried this in the last year and now I´m working on a new design 🙂 ---

i made the body and ring to not be press fitted so i’ll just bond the ring and the body together, and i could tune it while the glue is curing, and yeah the 3d printed mold is so disgusting the z seam is so noticeable and it’s not a perfect circle, it’s literally a polygon🤣, i was thinking about using resin mould or billet mould, but damn they’re so expensive ---

i’m pressing the yoyo out from the mould using a modified axle, i shaved the thread except the one that’s going to connect with the thread in the yoyo, maybe try to make the female mould 4 pieces, you split the body into 3, and 1 more piece for the response pad area, should be easy enough, can you share your mould design? ---

Could someone check if this bearing seat design is good in terms of machinability and durability? The yellow part is POM, 2.5mm at the thinnest part; the green and blue components are 7068 aluminum. Let me know if it’s helpful that I provide moredetails.

I pulled some details from the original one I made and one of my favorites that I have, the CLYW x OD Summit. I wanted a bit more organic geometry with flowing arcs and tangent lines. Everything is offset from or concentric with something else in the spun profile sketch. Machined this in two operations on my mill, starting with the outer face first. This allowed finishing the internal features, engraving the logo and profiling the outside diameter. Once this was finished I flipped the half and held it on an expanding 5C collet. This allowed probing the “finished” OD for concentricity then finishing the remaining features including threadmilling the M5 x 0.8 thread. For the bearing I ended up ordering a bunch of ABEC-7 bearings from McMaster. These worked out perfect for the spares I made from this batch since I gave them to family for Christmas presents and were slightly responsive out of the package. For mine I pulled off the shields and flushed the grease out then lubed it with thin oil. Spins well and is dead silent. It’s not as fast as some of my other bearings get but it’s getting faster the more I throw it. Most likely still some residual grease in the cage. > **[McMaster-Carr](https://www.mcmaster.com/3759T57)** > > McMaster-Carr is the complete source for your plant with over 595,000 products. 98% of products ordered ship from stock and deliver same or next day. Made this a few weeks ago and have been carrying and playing with it daily. Most likely going to bump the weight up 1-2g but otherwise real happy with how it feels.

That’s fine. The POM shouldn’t go any thinner and the 7068 shouldn’t go my thinner than 1.2 mm in important parts but at the bearing seat where it is less important to the structure you might be able to go thinner. ---
