This may be an old trick but its new to me.
My hobby lathe does not have coolant and trying to dribble in HP cutting oil whilst parting off it tends to throw it out before it does anything useful.
How to deliver coolant to the cutting edge ? Then it dawned on me to use a syringe :-
Delivered where its most needed and allowed me to go all the way in without any binding.
Parted off - warts and all.
I advanced the cross slide with my left hand while delivering (Rocol) cutting fluid with my right. I am a southpaw - maybe that helps.
The needle is cut off and blunted so I don't hurt myself with it.
The whole cut only used about 1.5cc of oil so its less messy as well.
This is the first time I ever tried this and I was so pleased with the result, I thought I'd share the tip.
Regards, Ken
