what kind of chuck you use?

My guess is a Nova?
The Oneway series would require a straight bit, I think?

It is a Nova. How would you make a dovetail recess with a straight bit?

That was my point... Oneway uses a straight jaw, Nova a dovetail..

I assume these are for grasping a spigot, or tenon. What I am talking
about is jaws that go into a recess with dovetail sides so that it pulls
the piece into the jaws as you tighten them.

When I was using spigot (straight) jaws I rounded oval tenons with a
hole saw. I left the guide drill bit in until the saw got started then
dropped out the drill bit and cut down the length of the spigot. The
original live center hole guided the drill bit for the start. This was
done on a drill press so there was no need to set up a jam chuck or cole
jaws.
