Well I do - it starts off a little more than 3" and tapers down to al little less than 3" at the outer end. I suppose I could mount a chunk of steel in the chuck and turn it to a 60* point.
That's what Keith Fenner does on his big lathe when he's turning between centers. I'd do the same if I had to use a chain hoist to mount and unmount my 4 jaw chuck.
Actually I do that anyways most of the time because most of my between centers turning is less than 1.25" diameter. And it's just easier to chuck a piece of bar and turn it to a 60* point than to unmount the chuck, mount the dead center and mount the face plate. Works great. I've go one piece of bar I use just for this. Chuck it up, turn it to true it up at 60* and off I go.

I also do that whenever I need to turn between centers.
