The original 'drawbar' in mine is a long bolt with a normal hex head (not a tall head like most mills have), and is hardly a fine example of the toolmaker's art.... it's a bolt, a black iron rusty grimy bolt bolt.[/QUOTE]

I ended up using some high-tensile all-thread with a couple of nuts + perm loctite on the end.
Good to know that it's prob no worse than the stock part.
