changing bearing size in a throw monkey

I’m pretty sure it would be possible to mod a duncan throw monkey with a size c bearing. I was just wondering if anyone could tell me how i should go about doing it.

I don’t think you can change a bearing size of any yoyo. because if change it, it wont fit.

You would need to recess an SPR into the yo-yo, which is best done on a lathe.


Or you can do the Protostar space and recess combo too. Either way, you’ll need a lathe.
