What model? My 1940’s record 52-1/2 is my absolute favorite tool in the shop.
Conventional wisdom from the old-timers here in the Ohio valley is: no lube – just keep it clean. Grease+sawdust is a special kind of hell. When I disassembled and rebuilt mine after getting it over here from England I did one thorough oiling with 3-1. Haven’t touched it with oil since. That was 7 years ago and it runs like a dream.
Individual preferences apply of course.
