Narrative:
While departing runway 1L, on SID pampus special, I was passing through 500 ft turning left to intercept the 006 degree radial off of ams VOR. I started a bank of 15-20 degrees and was less than 5 mi from VOR when the captain took control of the aircraft, banked 25-30 degrees and caused the aircraft to fly through the 006 degree course. I was given back control and told to reintercept. I began the turn to the right and was reintercepting when the captain again took control of the aircraft again banked approximately 30 degrees to the right. This action again caused the aircraft to fly through the desired departure course.
