I'd like to try and turn some single-piece darts on my lathe using

how to cut the 4 grooves in the flight(plastic "wings") end. Any ideas?

Depending on your equipment, the ideal way would be to use a slitting
saw in an indexer attachment, on a milling machine.
A minimill would do it, as would a $30 indexer with a collet to match
the dart body.

Problem is...the plastic flights are only 0.009" thick and are pressed
firmly into the slots. Are there jeweler's saws or slitting saws that
small?

I slit mine with a .015 saw (thinist I had)..then swaged em down a bit
with an over mandrel ..which was nothing more than a chunk of round
stock with a hole drilled in it a couple thous smaller than the od of
the shaft. I used bronze for the bodies. Some odd stuff I had
kicking around. No idea of the composition. Finally wound up busting
off the shafts over the years, drilled and tapped for commercial ones
later on. Came out to about 18gr, soft point for bar darts. Not much
steel darts around here.
