Narrative:

The right engine began to shake violently; but was indicating normal around 1;500 feet MSL. I climbed to 2;000 feet and told ATC we were returning to the departure airport; as a precaution. ATC cleared me for the visual approach and switched me over to tower. Tower cleared me to land on 30L. The right engine shook the rest of the flight. The precautionary landing was made without incident.
