Retired industrial glass blower, we made all the quartz furnace tubes and wafer carriers for companies like Intel, HP Micron etc. I am also a retired Flight Instructor, did it as a side job for 40 years and have been a RL pilot for 50 years with a Commercial certificate, Multi engine and Instrument rating. for fun I have built three airplanes, the first was a Gyro Copter which was scary as hell to fly, I them built a little single seat Volkswagen powered airplane called a Mini Coupe, it looked like a Er coupe with twin rudders. I then built and still own and fly a RV-6. It is a two seat hot rod, aerobatic and flies 200 mph on a Lycoming 180hp engine. When not messing with that I have a 1969 Camaro that looks totally stock but I have modernized the running gear, dash, and put a Corvette fuel injected engine in it. And yes it is true when you retire you don't have any free time at all :-)
