on the 19mm silicone pad groove part of the yoyo (mold actually) do i need a precise tolerance, or can i get away with general tolerance? because i’m not even sure if my design would fil the pad nicely ---

In theory all the yo-yo should be a tight tolerance although I believe most Chinese factories use a tolerance of .0006” for the general yoyo and .0004” for the bearing seat. Those dimensions for OD and ID look mostly fine I personally use an OD if 19.2mm and an ID of 14mm. I think the response pad depth might be a little shallow. I usually go 1.2-1.3mm. ---

There was another thread where someone wanted to make a Tungsten yoyo that was 2.4kgs: > [@I need help to build a 2.4 kilograms yoyo](https://forums.yoyoexpert.com/t/i-need-help-to-build-a-2-4-kilograms-yoyo/421250): > > Hy guys, I am a big fan of yo-yos and bladed weapons. I have a project to make a tungsten alloy yo-yo weighing about 2.4 kilos. I already have the possibility of having the materials, industrial 3D design and the industrial cutting. The problem is that I have no idea what type of yo-yo to choose. I would like a type of yoyo with a large volume of material so that I can increase the weight to the maximum. The ideal size of the yoyo would be 65mm in diameter by 45mm in width. (I can’t do mor… I made one: ![2.4kg_Tungsten_Front](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/8/6/2/862c6bccb4243374f366ba490e0a7b30219c87c3.jpeg) ![2.4kg_Tungsten_Isometric](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/5/6/7/5679b68c3f691e47d072caf5debae4dadf2c78e9.jpeg) ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/6/7/1/671ec9fb99560cb2995d1be8cdf774b1aeb029db.jpeg) Turns out it’s really hard to fit that much weight into a yoyo sized object.

The amount of mostly-fleshed out yoyo design ideas that have been flowing out of my head this past week is insane. It’s driving me crazy that I don’t have time to pursue bringing those to life right now, but just y’all wait a few months. I’m about to explode from the excitement. ---

Writing them down as fast as I can for now. When I have time, I want to really dig into how to do things right. I think at least a few of the designs are going to be really awesome, and I hope others will enjoy them too. I also need to invest in a 3D printer at some point so I can produce some designs myself (though having that ability could will be dangerous for my wallet). ---
