. Mainly because the node (internals) turn vs the Robust where the body turns. Both have through holes, the Robust though is threaded 3/8x16 for a drawbar I guess. But I don't know what you need a drawbar in a live center (I am sure to get some reasons).
Just so you won't be disappointed.
One use of a draw bar and which also requires the revolving outside housing is in turning thin stemmed goblets. I saw Stewart Batty tape the goblet cup to the live center and open the tail stock to put stretching pressure on the stem. He did not have a string steady that would work so he stretched the stem to take out the wobble.
Of course he could only rely on the morse taper holding. With a draw bar he could have really cranked it open. 🙂
