my new lathe (57 years old) has a dozen ball oilers in 3 different sizes. about 1/3 of them are broken (not bad for the age). have been looking at them online, most I see are cheap chinese ones. I found some GITS ones on their website but in a photo, they don't look like brass, which may not be a bad thing, don't know, never messed with these before. mine are the flush type with a barrel that taps into a hole and a small, flanged rim at the top. anyone have a source for quality made ones?
