One more sort of funny thing about uncle Bernie, he worked for a very highly respected aerospace company for 40 years developing all kinds of crazy things. When he retired, he was the only one who knew how to make a very specific type of klystron tube. The DoD still orders about one or two of them a year which keeps him quite well off since each tube is well into the six figure territory! He bought all the equipment when he retired and makes about 2 or 3 tubes a year on a quonset hut on the farm. Kind cool really. Even though I think he is a nut, I still sorta have to give him all due respect.
