I'm actually using a cough syrup syringe. The kind you get at the pharmacy for kids who need medicine but can't "drink" yet. Just a smooth tip with an opening about like a coffee stirring straw(smaller than normal straw). I think pencil lead would fit nicely inside the opening of the syringe.
Put some 3 in 1 oil in mine and pressed it down on the button and then leaned the syringe to one side and tryed it. It worked sort of. Made a big mess too!
Then I realized the spring under these things is not that strong. so I pressed the tip of the syringe into the ball until it was pressed down far enough for the syringe tip to be pressed into the brass ring rather hard. Then you use the hydraulic pressure from the syringe to force the ball down further and inject some oil into the hole. A little oil formed a puddle right on top of the oiler, but this way was much less messy.
I would have spoken up sooner about this but I figured I was the one that was learning here and everyone but me knew how to use the chinese grease zerks.
Tinker, I remember you saying you have the
Lathemaster 9x30? Well, I do to so I KNOW this method would work for you. Them damn rough cast holes beneath the zerks are filthy I tell you, Filthy! ;D. I used some small tube brushes to scrub out what I could reach before filling with lube. I will probably have to clean it regularly for awhile, I've noticed black streaks in the oil already and I haven't even started using the lathe! Just what gunk the oil has dissolved, running out under gravity.
Pay a visit to the neighborhood pharmacy and tell the pharmacist your grandkid doesn't seem to be getting any medicine down his throat with that little cup they gave you to use. Let him offer up the medicine syringe.
He really does want to help ya know.

This looks like a really nice hobby supply web site. Lots of stuff, but I know nothing about them. Anyone?
