Narrative:
Given clearance to enter left downwind for runway 24 [at ism] to follow [light aircraft] already in pattern. Pilot flying has considerably more flight time in various types than reporter. Pilot flying establishes tight pattern entry 100 ft higher than traffic pattern altitude. [The target aircraft] is flying much wider pattern and was initially in sight. We lose sight of the [other aircraft] entering the pattern; reporter establishes visual contact with [the target aircraft] at 1 o'clock; after [the target aircraft] turned its base leg. Approximate distance is 300-500 ft away; 25 below. Tower instructs pilot flying to perform right 360; no increased separation after turn. Pilot flying instructed to perform s-turns; which successfully increases separation. No further collision risk.
