Clipping problems encountered in the PRC at LLO have led to the discovery that the PRC scraper baffle "Z Plates" were built with an aperture approximately 0.75" too small. The PR2 scraper baffle assembly installed in H1 will require removal and re-work. For more detail please see the following link to the LLO log.
