Scota, your barrel is coming along fine. You are doing so well that I may have to send you any lathe work that pops up.
Bob, I lived on a 32' gaff-rigged schooner for 3+ years - that was totally off grid! Heck, few people had even heard of photo-voltaic cells then. Much less a personal computer. The IBM 360 that I worked with wouldn't fit in FOUR of my boats! Candles n kerosene, haul fresh water from shore.
