WRT safety, Yeah a LOT of guys in the 30's, 40's and 50's lost fingers and thumbs to power tools. I believe it was a matter of carelessness, sloppy work habits, forcing things, and just a less than decent respect of what the spinning blades can do.
It was fairly common for me as a child to see guys missing fingers. Other contributing factors could have been drinking (much bigger problem back then...), and smoking on the "job". (split attention...) Or maybe some lost them in the War (WWII)
Almost ALL my floor tools are vintage and near antique in some cases. I treat them with R E S P E C T... (Knocks on wood) and I have all my digits still. A couple of scars? Sure, but NOT from floor power tools... after selling 4 table saws I'm back up to 2 smaller both from the 30's, (one tilting table) 5 or six RAS, still have 3, WAY too many Drill presses, (only sold one so far) Vertical mill, H mil, 3 metal lathes, a couple three wood lathes, Band saws, chop saws, mitering saws, abrasive cut off saw, Grinders, both bench and hand held, routers, (routers give me the willies) router tables (less so) belt and strip sanders, so it hasn't been for lack of opportunity...
