Salty - Thank you for the prompt reply. I appreciate the thorough description on how to go about replacing Pegasus' hatch. Although a bit more work than simply tracing from a pattern, your description makes sense. I especially like the "Easy..." part (notice the ten thumbs!). And, yes, that's a good idea to include "ears". No more stuffing rags into the openings during a downpour.
