I Just set up my (from what I can find on the web, No tags anywhere so not sure) 1900-1910 Fay Eagan 12 inch jointer. I've never owed a machine with Babbitts so it's all greek to me. I do have a couple drip oilers ordered from Amazon but want to run it now. I don't have room for my 6 inch and this beast and my little benchtop unit has such short tables, it just doesn't do the job. As I said, I can't find a lot of info on oil weight to use. I plan to soak them down before start up but with what? I have bar oil for my chainsaw, as well as some motor and air compressor oil on hand but can pick up whatever I need. Any advice? EDIT: I know the drill...No pic...Didn't happen...Heres my proof! LOL! I also got a 3 horse GE IR motor and a second set of knives with it for $400 so, maybe not a full on gloat, still a pretty good deal in my mind. The only thing I'm unhappy with is putting it together by my self! I bet this thing is WELL over 1000 or 1200 pounds! I ended up breaking it down in as many pieces as I could and still struggled!279450

OWWM has lots on old machines, and how to keep them up.

Mobile Velocite #10 is my recommendation. I own a babbitted jointer too and researched the type of oil to use extensively. It took me forever to find the right recommendations, but this is what I settled on and it works great. I'm not saying other oils won't work. They very well may, but I know this one works for sure in my babbitted jointer application. I have my cutterhead spinning at roughly 4300 rpm and my bearings don't get hot or show any kind of wear using this oil. Hope this helps.

I use 5w30 in my bandsaw. It does turn a heck of a lot slower though.

It has been many years but I recall my grandpa using regular 30W motor oil on his Babbitt machines. Out of curiosity, anyone try a synthetic motor oil or zinc additive in this type of applicaton? There are lots of benfits to those in internal combustion applications.

Sounds about right. My dad always used a 20 or 30wt non-detergent oil on babbit bearings. He was a chief machinists mate in the Navy for 20yrs and lived inside aircraft carrier engines for several years, which I guess made him a pretty good mechanic.

The Mobile Velocite oil that was recommended looks good though.

I would use 20 weight non-detergent oil. You can buy it at Tractor Supply in 2 gallon containers. 90% of the time, 20 weight non-detergent is the answer to "what oil should I use for x?".

Velocite #10 is a spindle oil, designed for machinery with very tight tolerances and high speeds. I use it in my surface grinder and milling machine. It's very thin, almost like water, so I don't think it would be a good choice for a babbitt matchine -- it will quickly drain out and will need to be constantly added.

I have a 16" Fay and Egan Jointer. I use the same 30w non detergent that I use in my old Ford Tractor. Does yours have the square head? I had the head of mine reworked by a machinist to hold 4 knives instead of 2 - much smoother cut.

I used Royal Purple synthetic in my Porter. They sponsored our race truck so we had shelves of it. Never had to re-pour the bearings so it must have been ok.
