Good thought...according to a very strong legend in England, Jesus was supposed to have visited or stayed there during the silent years. The "isles" are sometimes mentioned in scripture. There is an ancient beautiful church there that carries the tradition that he helped build it...
According to archeological eveidence, there are remains of a city called Sepphoris , 4 miles from Nazareth, which has proven to be very metropolitan for the times. Herod Antipas chose this city as his capital. There were alot of elaborate building projects and Joseph and Jesus were probably employed there. Also the greek word we use for carpenter actaully translates as "artisan," which has a broader meaning. Jesus may have been involved in stone work , masonary woodwork, and other types of construction.
