"and how indeed they could be held on a Lathe, in fact I might just take that with a pinch of salt"
:roll:
I would think that you would hold a cast patera on a lathe in the same way that you would hold a copper-alloy helmet on a lathe when spinning it, which the Romans certainly did sometimes according to Robinson. Pressure from both sides! I assume that this is how it is still done. I don't think magnets or gaffer tape would work nearly as well as direct pressure even today. If they could spin helmets on a lathe then they could spin paterae while skilled hands pared the sides down. I seem to recall Lindsey Allison-Jones mentioning visible spinning marks as well. I believe that I am far from the only one here who trusts her well informed statements.
