Why? "The term blacksmith derives from iron, formerly called “black metal,” Blacksmiths existed long before any exports out of Africa.

Roughly size I ran a couple years, 30' and 40'. Any table length requires twice that of bed and ways, but that's why they did such fine work. None of that potential table sag or binding ways of lesser machines, or concentrated wear.
While planers technically operate as 'single point' machines, they have reasonable feed rates, of course lost some time on return stroke. Worked out beneficial on certain kinds of parts, such as weather stripping molds, wing spars, machine skids, and tables of smaller machine tools.
Examine the foot of a large radial drill, I've seen tool marks that indicate planing and scarf milling, both easy work for a planer.
Scarfing of that variety employs a slightly tilted spindle and turning cutter. They step cuts over a bit more than cutter diameter, leaving shallow grooves with narrow lands between, accomplishing part of what scraping does.
Overall, planers did reliable work on parts with very long but small profiled features. Also remains maybe best at undercutting, where an endmill or other rotating cutter just can't enter.
I often wonder how many remain in operation. Extrusion has taken over what long compression molds did, with far more compact machine footprint and tooling.
