Rainy today. Decided to do some inside work. After nine years in the new house finally got rid of the OSB scrap that rested on the back of the sink. It was developing some black mold on the bottom. Not the best where beer is fermented. Back splash if three-eighths inch thick. Same composition as some synthetic cutting boards like the one hanging on the left side.
The cabinet on the right goes this winter as soon as I have the new shop organized.
