I understand that to turn a blank whose ends are not exactly square a

The stebcentre has the same problem as the 4-prong in that the portion
of the blank nearest the headstock will be gripped more firmly than
the part furthest away. Not a good idea. If you must use blanks that
aren't square on the end you really have to use the 2-prong. Even that
won't work if the angle on the end of the blank is too severe.

Personally I'd find a saw, chisel, or sander and just square the thing
up and mount it properly.
