Here’s a tip for finding the pivot on a Rega and some other arms when using the Feickert. With the arm on the lift I place a 3/8” square of sticky note with a dot in the center over the pivot. With the Feickert pointer over the dot, I’ll swing the arm towards the spindle. If the dot moves from under the pointer, I missed.
That's a great trick! With some arms, it is difficult to locate the exact pivot point - this solves it!
