The landing gear was extended for a training maneuver. The main gear extended but the gear unsafe light was illuminated. The gear was recycled twice with the same result. Manual gear extension procedure was attempted per the flight manual with no change in results. Ptk tower was notified and a flyby down runway 9R was performed for the tower to visually observe the gear positions. Tower reported that both main gear appeared in the down position and the nose gear remained retracted with the gear doors partially open. Normal and manual extensions were tried again with no positive result. Three attempts were made descending with the gear extended and abruptly pulling up just before maneuvering speed was reached. The maneuvers with additional g force did not free the nose gear. Tower was notified of intent to land. On the final approach the mixture control was pulled to idle/cutoff at 200 feet above the runway. The engine quit but the prop continued to windmill. Landing was made on the main gear at the slowest possible speed. The nose settled very quickly and the aircraft slid straight ahead to a stop. Damage limited to nose gear doors, skin adjacent to nose gear doors, exhaust pipes, and propeller.
