To hold small pieces, I normally would use a vac system for cleanup, sanding and rubbing out the finish. A situation arose where the vac was not an option so the following pics are what I came up with and they seem to meet my needs.
224026
Three pieces with #2 MT, all three have a .625 tenon, one of which has a .25 tenon also. On one, the end of the .625 tenon has a 45 degree counter bore used for aligning .25 stubs.

This setup is for holding a base or lid.
224033
In this case, it is a lid that has a .25 hole which fits over the .25 tenon, the tailstock piece is turned to the contour of the bottom of the lid and serves to help center and assist in the lid running true. Light machining can be done in this configuration if needed. I will sand the top of the lid at this time.

The tailstock is backed away and now the bottom of the piece can be sanded.
224029
This setup is for the cup.
224035
The MDF is turned to fit snug in the cup and the .25 tenon on the bottom of the cup is centered using the counter bore of the tailstock piece.
224036
Light machining and sanding can be performed with this setup.
I forgot to get a picture showing how I sand the inside of the cup. For that, I use a .25 collet chuck to hold the .25 tenon on the bottom of the cup and place the MDF piece in the the tailstock to center the cup, then back the tailstock out to sand the inside.
I have found these three pieces to be very handy and use them frequently. There are times when they are quicker and easier to use than the vac chucks. They are turned from 6061 aluminum but do not see why a good dense hardwood would not work also.
One note, these only work on the live centers that accept a #2 MT, such as the Nova.
