This is a problem for me too, I currently have a loan lathe here as well as my own, and the loan lathe has an Axminster chuck which will just about hold the blank, but not as well as the jaws in that tutorial, and its going back next week, so I have to come up with something else.
I went out to prepare a load of blanks the other evening, but soon got bored and did some turning instead :lol:
