Here's another little jewel, that no mechanical
geek worth their
salt should be without - the General Tools 589 Precision Oiler. This
is a high-quality, leak-proof refillable oiler, that allows very
precise dispensing of even the smallest droplets.
I use a plain medical glass syringe with a fine blunt tip needle for
that. I've also found that orthodontic wire cutters work very well as
flush cutters (and almost as inexpensive as the regular electronics kind).
For a light oil, I dig into my supply of brass instrument valve oil.
All types are available, from regular petroleum-base to some pretty
exotic synthetics. Go to, say, Amazon and search for "Trumpet valve oil".
