OK,
I've worked on a Vision machine, with that (split-collet) spindle configuration, although, I've never tried to use a featherlite adapter with it.
As you're discovering, they're not condusive for use with a burnishing adapter.
Have you tried finding a delicate balance, between barley tight and loose?
If that makes any sense.
