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.
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. :lol:
This is from Home Depot just under 1 liter for $9.00

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.
I have never used any of the animal fats or vegetable oils for coolant and lubrication in machining, mainly because for the past 35 to 45 years I have always kept Chevron soluble oil B or another brand on hand But mostly the Chevron product. The mix ratios can vary from 15 to 1 to 50 to 1 depending on application. When I had several machines running more or less constantly I bought it by the 55 gal drum Now I only keep a 5 gal pail on hand I've had the same pail for over 3 years, @ $70.00 to 80.00 per pail it is the cheapest solvent or lube I've found Since currently none of my machines have flood or spray units working on them I just mix up a 2 ltr. drink bottle with a small hole in the cap
