are those two pieces truely both cast iron?

the dry static friction of cast iron on cast iron is "stuck together" (CoF>1). a little grease will make it slippery (CoF <0.1). I would think one should be a mild steel [CoF ~ 0.4)

If they are both cast iron, maybe the local vibration prevents a true static and the dry sliding CoF would be about 0.2. a dab of lube still sounds like it would be highly desired
