When I was twelve years old I worked full time for my uncle in marine construction. Also welded boilers and pipeline plus operated heavy equipment but putting bridge pilings in and running pipe on a hill and figuring rise and run gave me such an advantage with the quality of mechanical /foundations portion of solar operations that it was just second nature for me to keep plane of array and pile north south east west alightment almost perfect and that’s something I teach all the way down the line to the lowest man on the totem pole good pile makes good torque tubes which makes everyone else’s jobs down the line easier easier means less work less remid all an all you start right and stay right you end right
