Ball type oil nipple & oil injector

A sheet metal screw works fine to screw in the hole and then lever the oiler out. Do not push the ball below the surface too far or it will go sideways into the corner. You will likely never get it back again. I use about 2" of clear vinyl plastic aquarium tubing on the end of my pump oiler, cut off square, and push that down on the ball and then pump oil. The tubing seals the interface, the pump overcomes the spring, and you can see the oil flowing into the oiler, and nowhere else. It also keeps your machine from getting scratched by the oil can tip, and the oil can is still completely useful for other tasks. The tubing needs to be replaced about twice a year because it gets stiff.
 
Good internet sleuth-age. That's got to be them.
 
had to quote this as I was looking around my shop laughing......no offense meant, just cracked me up the way I work....
Some people really care about keeping their stuff pristine. I like to keep things in good shape and in good repair, but these are machines to work with, not to spit polish. To each their own... I just added it as another plus of using that method of oiling machines.

Pump pressure overcoming spring seems to be standard solution. Is that necessary? Are ball oilers used as a check valve with substantial oil pressure?
I couldn't find suitable oil can for my minilathe (all commercial ones leaked badly) so i build adapter for medical syringe - and to reduce spillage "business end" contains push rod moving ball out of way - oil can be injected with minimal pressure. Works great for minilathe but will be messy if i ever use it on something with pressurised oil
 
Somewhere I saw where a guy made his oil can work better for oiling the ball type fittings.
He cut a slit or X across the end of the tip of the oil can's nozzle . The nozzle tip pushes the ball down and the slit or X breaks the seal and lets the oil flow.

The ball and spring are to keep contamination out.

That sounds like a way to drip oil all over the outside of the machine. Ball oilers are installed in vertical as well as in horizontal orientations. The idea is to get all the oil in the hole, and for it to stay there. Slits might work at adding a drop of oil a second, and then letting it work it's way into the small opening, at least in oilers installed on horizontal surfaces. When I oil, I want to get the oil in there, under pressure, no fooling around, and without wasting oil or leaving a mess.

Not necessary, the tip breaks the seal, the pressure from the oil passes the oil past the ball. Too much overthinking .
