Not completely accurate, but I wish !
The 2 days a week are days I answer the telephone.
Those of you who are capable of multi-tasking (i.e. doing precision machine work on a lathe or a mill while answering the telephone) have my admiration. I am not so talented.
As to "work" hours; there is a old saying about those of us that are self-employed: "you can work whenever you want.............AS LONG AS IT IS 80 HOURS PER WEEK"! I generally am at the shop at least 6 days a week, and sometimes more.
