Vacations always break my routine unless I take a model with me. We took a week off to go to Wisconsin a week ago. for example, I didn't take a model to work on and now I haven't returned to the bench since. Now I feel like I'm in a slump period. " I'm retired, I don't need vacations," I keep telling her. Other than that I would say engine detail always slows me down. I haven't done any brake lines yet like some of you.
