As I recall, the Super Nova will take the original Nova jaws.
I also recall that I bought some Oneway jaws to fit the Nova, and thus they
will fit the
super nova. Depending on your budget, the super nova is a step above the
nova (actually a real nice big step), the the Oneway Strong hold is a
jumping step above the super nova.
And there are those that argue, maybe correctly, that the 6" or 5" vicmark
are superior to both of these. I like tommy bars and bought a 6" vicmark
last week with the
smaller jaws that come with it and the large jaws and then
I also bought the super large jaws....they will handle recesses or tenons up
8" dia. I visited Mike Mahoney (of Utah and multiple natural edged
bowls from a single piece of wood, using the McNaughton center saver, fame)
and he demonstrated using
the 8" tenon on rough turning and coring out multiple bowls from a single
piece of wood.
Of course during finish turning he turns down the tenon to the correct sized
