I think I need to get an oil gun. Can you tell whether you should be applying oil or grease by the shape of the nipple ? Grease nipples seem to have a ball fitting on the end, and I have some nipples on a lathe which apparently need oil and just taper to a flat end. Then I have some old electric motors with ball ended nipples, so can I assume they need grease ?
And if I need an oil gun, then where do I get one and do I need a special type for oil nipples ?
I realise this is a dangerous thread to launch, so please try to resist the obvious digressions and stick to machinery lubrication.....
