Taig also sells a WW headstock with drawbar. You can use normal WW collets. Taig does not sell those, I bought mine from Sherline. The WW headstock has the same external thread as the standard headstock, so you can use all the standard accessories as well. Only the bore of the spindle is smaller than the bore in the standard headstock. Attached is a picture of mine with a .3mm collet.
