Stopped by to see my long-time friend Jack Fulton last week. Jack is by profession a photographer, also a builder. In the '60s, Jack and I learned a lot about building from Jack's uncle, Alec Fulton. A jovial Scotsman, Alec took the time to teach us novices. Among other things, he taught me how to join cast-iron drainpipes with hot lead (and oakum) — in the days just before ABS and PVC drain pipe replaced cast iron.
