Since this thread has been bumped, I will add that I have made an ER11 collet chuck following these steps almost exactly and it worked well.

(Why ER11? I wanted a way to mill and drill in tight quarters where a drill chuck or endmill holder wouldn't reach. It works very well in both lathe and mill and, as best as I can tell, it has very little runout. I hold it in either machine with a collet: MT3 in the lathe and R8 in the mill.)
