Do you own a lathe or know someone who does? If not just go buy a yoyo with a bearing in it. It will work out better all around. ---

Now you have to figure out what size bearing you want in there. Fortunately, there’s many places that show dimensions for common yoyo bearings. ---

In any event, if you are looking for a project, then carry on. Probably your best solution would be to purchase a Duncan Ball-Bearing Yo-Yo Parts Kit. That will the bearing seat you need and a bearing to fit. ---

What, a wood axle and a wood transaxle? Man, we’re talking gobs of friction there. I like the idea of the Duncan kit. I think isn’t there some Crucial SPR kit that sort of does something similar? ---

Me too. Tom Kuhn RD-1. Wood yoyo, modern guts. Seems a more productive use of my time to buy one soon than go and modding something else. ---

The hole in the middle allows the standar 4mm bolt to go through it. Also, there is a groove for the string to sit in the middle, like a center trac.
