Arch,

My understanding of the specs for the Nova 3000 is an outboard swing of
23". I once did a 16" platter, outboard on my old Delta Homecraft (10"
swing). The slowest speed was something like 875 rpm and the wind
generated was something. The 3K gets down to 250 rpm so I bet 23" is
not a problem if the blank isn't too out of true.
