That may work, but the workpiece has a "ball end" kinda hard to make a series if them with that end on them.
You CAN make them one at a time, if that's what you mean, but you still have the issue of support of a round object which may want to rotate when the blade isn't centered ?
It's hard to know his process for making them. Maybe chuck up a long round and shape the ball, cut it off and start on the next one.

I would use a 1/8" paring tool to indicate the length of each piece. Round the top into it. Cut the belly out. Using a sander you could cut the top bevels in. Mark your edges. Good luck.
