I was cutting some ash blanks this morning and it was scarey when you cut the
circle and the bottom face of the blank is a lot smaller than the top face, and
you can see naked blade between the wood and table..

It's not the naked blade that worries me about that, it's the lack of
support across the narrow base. It'll tip, and that's a great way to jam
a blade and kink it.

A bracket or false table to support a pin from beneath is a much quicker
and safer way to guide a blank flat-side down. Failing that, attach a
wire guide from the top of the saw and mark out the centre on both sides
of the bowl. They're only blanks - accuracy doesn't have to be that
close until you're turning them.
