While a little hard to see, the pins mount in holes drilled in the end of the pendulum's hook-shaped protrusion. Once mounted, I marked where they sat on the hanger, and drilled holes to receive the cups. It sounds more complicated than it is; here is a zoom-in of the installation.
In the process of installing the pins, I snapped off the pendulum's hook. So that is now gluing. Once it's dry, I'll be able to tell if this helps to reduce the pendulum's running friction.
Update: after drying, for the unloaded pendulum, I get a median of 71 full periods for the amplitude to halve. That puts the unloaded Q = 320, which is a little bit better than before.
