'Bigger Cousins'......oh yah. It could be learning to run woodworking machines cemented my respect for stout metal-working machinery. I especially remember Oliver table saws. No sheet metal nuthin', maybe the knobs and handles were plastic.
They woodwork equipment is modest; 2 tablesaws (1 the tiny Monkey Ward), 12" 1950's Craftsman bandsaw, DeWalt planer, the usual power hand tools. I'd add a shaper if an iron version comes along. I've been asked to replicate old patterns of molding heads (homes dating back to 1860's here), it would be worth testing them.
