@Ragman,
I learned "On the job". I was on a project as the groups leader and got really bored becuase Ireally had nothing to do on schedule and Is just get in the way. SOOO, I started helping the carpenters make CORE BOXES (and learned some nwat tricks in cutting and mmeasuring. Ive been doing woodwork off and on most all of my adult life and didnt get really fst till I sid that core box work.
My family ad Mrs F's side all get some handmade stuff by us very few years.
Now Im into fine finishing and faux finishing I karned "French Polishing" a few yers ago and ran across a YOUTUBE thing on it and I needed a way to get a high glass finish. So I worked on the F Polish and it is time consuming but brilliant as a finish
