I have two Duncan Bearing Kings. One I keep set up as fixed axle, the other set as a bearing tip. This is the one I’m talking about.
The stock spin kinda blows. I took out the two bearings and then I did my typical cleaning treatment that I do with bearings:
Mineral spirits bath, dried thoroughly, then in acetone. Repeat. This time, Terrapin X treat BOTH bearings.
You MUST do this!! I can’t do much but the top spin for over a minute and when I picked it up it was still going strong. Wow!! Even just cleaning the bearings out completely was a massive improvement, but then adding the Terrapin X treatment: wow!
I’m gonna spend more time on spin tops. I want to work up to the Sophia I have.
