It is always interesting seeing specialty hardware. I’ve never built a lamp and had never heard or thought about cutaway couplers or hickeys.

Kaerlighedsbamsen, I’ve wondered about this too… a channel routed on the underside of one of the feet,  threaded inserts on the contact points, and turning the brass locator pins into structural bolts (one being hollow for the wiring). It’s fun thinking up new ways to make Ross contemplate extra work. 😀
