Vegetable oil as a cutting oil for machining?

[fandres]

I use chainsaw bar oil most of the time and it works well and is a lot cheaper than cutting oil $10 for a litre of bar oil compare to $50 for 500ml cutting oil.

Where did you find that price $50, I bought 20Lt for that.?
I agree chain saw bar oil is good for a lot of operations though I am sure some will disagree.

Some of the best finishes I have seem and produced were with a small brush and Crisco.

I'm with you bobs409, that smoke is not good for the old lungs. I keep the garage door open when doing any kind of machining. Also have a small fan moving the air across the work.

I also read about lard. My new wonder lube is Fluidfilm. Got turned on to it by a guy who did machine reconditioning most of his life. It's lanolin based and non toxic. Not tried for machining yet but everything else I've tried it on has been amazing.

I have a gallon of their thick Fluidfilm and will have to try it out, I got it for rust protection and was ok not spectacular.

There is one draw back to some types of cutting oil is it give you cancer
FYI I found out this the hard way

Today dry machining and only use oil for threading

Well after trying the vegetable oil for a few days, I'm done. lol It does have a smell that I didn't notice the first day. I watched a video the other day and the guy was using bees wax but he was machining stainless steel. Wonder how that would work with regular steel? Might try the Crisco yet too.

I hear the best lubricating-cooling (cheap) option is pork fat (pork butter? in spanish: MANTECA DE CERDO)

I agree on the Lard oil, applied lightly with a brush from its buttery stage, it works well and is what is recommended in all the older machining books I have. You can mix in a small amount of turpentine to keep it from 'going off' and I keep my tub in the freezer when not in use.
