So a buddy and I want to make a yoyo. We have enough cash to start up a company, buy the software and carry out a few prototype runs before doing at least 2 production runs. I am familiar with 3D design software and took some courses. My question is…is there anywhere I can find the specs for the response groove, bearing seat and post? I have a digital micrometer but I’ve only worked on larger parts that were to be machined like faucets and light fixtures…nothing this small before really.
any help or suggestions would be appreciated.
