Sanded micro on cowling. Cut exhaust holes so that they would be even and parallel with the spinner back plate. This was accomplished by taking little by little off with a body saw and die grinder and measureing with an electronic level along with the mark-I eyeball. Cut cowling apart at the fiberglass added yesterday and filled some depressions on edge of exhaust holes with milled fiber and flox. This was done with an eye to future work to make the holes a nice oval shape.
