Can you clamp the workpiece to the cross-feed of the lathe and put the reamer in the chuck? I know that's kind of backward, and may take some fiddling to get it lined up with the headstock, but might be worth a try. You might have to machine something to get the work at the right height, but lining it up horizontally should be a piece of cake.

Or maybe stick some round stock in the opposite end for a center point and machine a piece that will slide on it that's supported by a steady rest?

[on edit] Sounds like Jerry got there first with nearly the same suggestion.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
