Does anybody have a suggestion for a reusable precision oiler? I would like it to deliver single drops which would be appropriate for delicate applications such as some firearm points, individual bike chain rollers, small threaded or pivoting applications.
 
If I have to apply a very small amount of oil or adhesive, I'll use a home made "watch oiler". I take a piece of solid copper wire, usually 18, 20 or 22 gauge. Form one end into a loop handle. The other end gets flattened by placing it on a vise and striking it with a hammer. It's crude, but effective. Put a little oil on the flattened end and then touch it to the part you want to oil. The oil wicks off the "watch oiler" and onto what you want oiled, and you can easily control the application.
 
I have used hypodermic needles with good luck. 10cc seems to be the ideal size. I dull up the tip with a Scotchbrite wheel to avoid needlesticks. Make sure the plunger is silicone and not butyl like most of them are. Medical grade silicone plungers are grey in color. Butyl are black. If you try to use butyl, the plunger will swell up.
