I'm in the process of modding a Trompo Grande the I recently received from Science of Spin/YoYoPlay. It has the brass modified diabolo tip. My problem is that the weight ring rattles. I can press fit the crown so that I don't see any gap between the crown and the body anywhere and I can hear the smallest rattle, but once the top is dropped even from a small height, the ring will start to rattle again.
Any suggestions? Thanks, rick
