Air tool lubrication: how do you do it?
Starting to think about setting up an air system in my shop. The compressor still sitting on its pallet, but at least I got it home and unloaded without anyone getting hurt. 😉
My question is what to do about lubrication, for the tools that need it. I plan to put in a separate line for spraying, so that’s not an issue. But there are three ways to supply oil to the tools that need it:
1. wall-mounted lubricator installed with the regulator & filter.
2. mini-lubricator installed in the hose just ahead of the tool.
3. just put a couple of drops of oil in the tool before each use.
#1 seems the most “set and forget” option. But if I go with that method, I’m worried about hooking up a blow gun to that line and spraying oil over anything I blow the sawdust and wood chips off of. #2 seems that it could end up being a pain, having to mess with the minilubricator that doesn’t hold much oil and may end up getting in the way. With #3, I wonder if the tools will get enough oil.
I know there are nailers that don’t require oil, but the choice of nailer gets bigger if you include need-oil units as well, and I want to use other air tools that do require lubricating oil.

Just put a few drops in at the beginning of the usage for the day. The inline oilers are more a pain. You tend to run out of oil long before you notice it's out and the wall mouted ones are more suited for an inustrial station that runs the same tool constantly. In line oiler are normally set to give a very small amount of oil so you don't have to worry about dripping oil. Make sure you plumb up your system correctly or you will have water problems. It's not like plumbing your house. Use type K or L copper if you don't use black pipe. There is a new type of plastic airline available but it's expensive. PVC is a no!

No problem really.
Just use a different quick connector for the oil line.
That said, I just put a drop or 2 of oil in the tool once a week.

"3. just put a couple of drops of oil in the tool before each use."
Just remember how much the tool cost, and how much the bottle of oil cost and you probably won't forget to oil the tool.
Two drops in a finish gun, or three drops in a framer, and yer good for the day.

Thanks guys. 'guess if I can remember to drain the tank and the lines, I can remember to add a drop or two of oil.
I was planning on using copper. 'would rather not have to worry about iron pipe rusting, and copper seems easier to work with (I solder pretty well). Thanks for the .pdf; I didn't know about the 8" riser when transitioning from a vertical drop to a horizontal run going to the filter/regulator.
I already hung a reel with 3/8" hose from the ceiling ('sucker was heavy). 'now just need to hook everything else up.
You could always hook up a double head at your main stations. One could have an oiler the other be dry ait. That way, you would have the option of which to use.Lazarus"Wisdom is the toughest of teachers! She gives the test first and the lesson after."
having considered the same options i chose a section of 2x10 for a wooden base with a tee made of 1/4x1x3 crs(2 holes to screw into base) welded to a 1/4x1x1 angle/iron upright(2 assemblies needed). after screwing these assemblies to base ,i hardpiped(1/2") the moisture trap,regulator,oiler assemblies with female/male quick disconnects at ends (one at each end). this may seem like overkill but it provided me with a suitcase style unit that i could store under the bench and allowed me to use a dedicated shorter length of air hose. if it became oil saturated after a year or so i could replace reuseing same quick dissconnects...the bulk of my shop hose remained oil free. i also use a product called kroil as the lubricant...i use it to cool my drills in metal, automatic tapping head threading, and any rusted bolt/nut, bearing,etc. a gallon cost about 15.00 the last time i purchased. plain_james
The real issue for me is the ceiling reel. If I inject oil ahead of that, it'll be "contaminated" and I won't be able to use it for no-oil applications like the blow gun for cleaning off sawdust, etc. It's too expensive to put up a second one.
I'll go with the "couple of drops before each use" method for now.
You rarely will go wrong with the low tech solution.
Just oil the tool before use, per the owner's manual.
