PM727 ball oilers suck

[coffmajt]

They do not have a shoulder, they are the same as whats in there, just a press in, but no shoulder. Jack, do you happen to have a picture?

Yes I do. I removed the ball types, then carefully drilled and tapped the holes 1/8 pipe thread. I used heavy grease while drilling and tapping to trap and hold the chips, then carefully cleaned each hole before installing the zerk. I use the German oiler designed for Bridgeport with Vactra way oil and it works great. Jack
