Needle Valve Sight Gravity Drip Feed Oiler - What tubing have you used?

[Nightshift]

Metalmuncher, those needle valve sight glass gravity drip oilers work great on old machines to keep bronze bushings properly oiled. You are gonna use pretty lightweight oil which will gravity flow down a very small tube.

I first put a couple small 1 oz ones right on the bearing caps of my Southbend lathe. I just drilled and tapped the cap for 1/8 PT and because they are right there in your line of sight whenever you're working on the lathe, its easy to remember to flip the levers to turn them on. The harder part (for me) is remembering to shut them off when I'm done!

I also put a 3 oz oiler on the side of my Do-All vertical bandsaw. I just have a standard 1/4" PT fitting going thru the saw frame column with the oiler mounted on a 90* on the outside and then an old 1/4" hydraulic hose on the inside to direct the oil flow to the bearing on the variable speed pulley. Works great! Bill
