Just finished doing a mild restoration on this Kundo. All apart, cleaned, spring serviced, back together. But I am not sure how to proceed getting the torsion spring off the pendulum. Looks simple enough. Don’t want to force the pin out. Is there another way?
Raise the collar against the spring to expose the steel pin that holds the block in the top of the pendulum. Tap the pin out with a punch. After that I usually file the crimp on the center of the pin to make it a loose fit so it will go back together without using a hammer.
