I put a 4 inch hose from the dust collector in front of and centered on the piece being cut. It doesn’t get it all, but it gets a lot of the chips. If you come up with something better that would be nice…lol
Look at YouTube videos on woodturning and you will see many different designs using different types of hoods to capture the dust. There are some great ideas there
Take a shop vac vacuum head,
duct tape it to the bottom of a TJ Maxx bag.
Cut out the bottom so the vacuum can suck up whatever is in the bottom of the bag.
Hang it under the rotary axis.
