Ideas?

Yes. Instead of a straight reamer, make a set of squeeze blocks with bored tapered holes. Same setup as making the Luger barrel vise inserts, but in steel.

As to the finish, I have had excellent results wrapping blued Luger barrels with one layer of masking tape when turning them in or out via the barrel vise. Whether this would hold up under 100 or 200 whacks with a brass hammer while clamped between two blocks of steel in an arbor press is unknown to me. Perhaps a hydraulic press might be more forgiving.
