I started the morning with cutting the sides of the top of the sliding hatch so that er was enough room so the hatch could slide nicely under the top. I partly cut the entrance bigger and trimmed the front of the sliding hatch. Before lunch I cut the top of the fridge flat. In the afternoon I did grind the edges of the sliding hatch and the top so that they could be filled with putty. After the filling I started with the top of the fridge and cut some foam and glued it in place.
