I tried an old time LARD OIL recipe for cutting steels....

[Ultradog MN]

Speaking of chemicals that used to be common but now are banned:
Another one is Carbon Tetrichloride.
I have some in our kitchen.
This is a vintage fire extinguisher.
It has a small hammer attached to a spring and a heat sensitive link that will break the glass in case of fire. Bell goes ding a ling.
It was in the basement of an old house I bought years ago and has stayed with me ever since. You can buy them on fleabay but they remove the carbon tet and refill them with water. Mine is still loaded as it was.

They were criminals and
paid a small price. Stop while you are ahead.

Where you went off the rails was blaming Republicans. No one's crap smells like perfume.

"That's wrong. Always was, always will be."

a) You are preaching to the converted, nobody in this thread is advocating or approving of dangerous chemicals being
dumped in the river.

b) PM is a brilliant site, it took you nearly 18 years to register your one "like"!

c) The Commies managed to damage their local, and sometimes not so local, environments to a greater degree and, simultaneously commit more murders in a shorter time than hitherto possible.

Many people believe "That's wrong. Always was, always will be." but none of them are holding their breath waiting for you to apologise.

I'm interested in seeing how long it lasts before it spoils from the lard. I plan to report back when it does go bad so that others have an idea how long it could last in a shop fridge.

You could try putting a small amount of vitamin E oil in it. Vitamin E is a natural antioxidant used to make cosmetics or lotions last longer on the shelf.

Jim, if you look back it would seem that you started the politicizing. I'm not sure what difference it makes to the fact at hand. Anyone can make an environmental mess of things.

And I don't mean to single you out. It's getting awful tiresome with all the divisive garbage going on around here. You guys are all starting to sound just like the politicians. Bitching about everything and everyone else being at fault non-stop instead of trying to work together, compromise and find solutions to the problems.

It's not commies, liberals, nazis, or conservatives who are responsible for the damage to the planet and our health, it's humans.

Greedy, ruthless, short sighted, or just plain ignorant.

I doubt that there are any categories of people that could be fairly evaluated as entirely made up of good people, or entirely made up of bad people.

I'll also concur WHOLEHEARTEDLY with eKretz's last paragraph in his above posting. Well said, Eric.

Crisco was mentioned earlier.
To keep percussion caps from flashing over to the next chamber and firing black powder revolver chambers out of line with the barrel I started using it years ago, as many do.
The last time I went shooting though the Crisco smelled really terribly nasty, so I wouldn't agree that Crisco can't go rancid (Or whatever it was that made it piercingly stink!)

We used to pack the inside of hole saws/tank cutters with tallow. As the cutter got hot the tallow melted slightly and lubricated the cut. It worked a treat.

Regards Tyrone.

We used tallow on the slanted wooden ways we built guided missile frigates on. When we knocked out the restraining block the ships slid down into the water smoothly.

But I always thought lard oil for machining was extracted under pressure from pork fat.

Probably mostly because it goes bad fast

Not my experience over a few decade with plain old lard.
My wife likes bacon. every few years i ask her to save some in a tin or jar, & take it to the cellar shop for occasional brushing on rough lathe work. It never spoils, but will eventually get hard as a rock. I have seen (rarely) a little green mold on some really fresh stuff. But that scrapes off, and never had any smell.

Per bees, we keep excluder bars handy. They are a common commercial item. Turn them to the side with the notch size you want to use. Though in truth, i usually make them from scrap; or just grab a piece of scrap when there is evidence of a raid commencing.
There is so much wax here i have tried it for tapping. It's better than nothing on steel but probably not as good as regular larded cutting oil (Nu-clear larded pipe tapping oil) or other commercial products including the bean-based stuff. Actually, for wood, beeswax is not bad especially if the tap is warmed to melt it in place in the lands.

I used to use Tap Magic and Cool Tool back in the 1980's, great stuff. One time, one of the local cutting tool suppliers gave me a quart can of what was called Honykut or some such spelling. That stuff was nasty smelling, medium viscosity. It was amazing for drilling steel, never used anything like it before or since. The only problem with it, about a week after using it on the drill press, the chips, table, and column of the machine were all stained with dark brown rust. It's one major draw back. I gave it away after I saw that, with a warning to the recipient.

I remember using something like that also, when they first cut out the trichlor. It worked decent, but not as good as TapMagic or RapidCut with the trichlor. But i I vividly remember it rusting the crap out of anything it was left on.

Since about 2015 I've accumulated about 1.5L of bacon fat as I keep filling new empty cans and not getting around to disposing of it. It's been at room temperature the whole time and none of it smells at all.

Be fair here now. When was the last time you saw a republican in favor of any environmental regulation. The typical response is, "those damn greenies."

Privatize the profits, make the environmental costs public. It's the standard rule.

Don't sound like your upholding your Canadian Heritage.....
Should be 1-2 liters a year.

a bit sideways comment. I am an artist working in oils,several years ago i came across the old fashioned way for processing linseed oil called water washing. using hot salt water and silica sand. its messy and time consuming but makes a vastly superior oil. lots of old recipes out there that are not available commercially because they are expensive or impractical to do on a commercial level but they may be otherwise superior. back 40 years ago at my fathers company we used lots of hot animal glue to glue paper, cardboard and wood. i was always looking for something better, but that was hard to beat other than making the place smell like a horse barn. When doing turned edge work the girls used "bones" which for some reason werent available for a while so i tried making replacements out of HDPE and hard rock maple, etc, nothing worked as well. eventually we were able to get the bones again, i believe it they were orginaly ivory which worked great and the eventual replacements might of been cuttlefish bones, but the vendor wasnt saying.

 

[Toolmaker51]

I have asked the wife to make bacon tomorrow to see how it works.

Makin' bacon?
Shop-wise, most of us find that counter-productive to getting work done...
See how that works?

DIY cutting fluid

Just curious and had to ask.... I noticed a lot of cutting fluid contains sulphur, and some like Mobil say they are sulphurised mineral oil. I have a gallon jar of sulphur powder. If I dissolved some sulphur into regular mineral oil would I have do it yourself cutting fluid? Or just a big mess...

I don't know why the link changed the title to "Oops..."

It's a linky to a 2005 discussion here at PM.
and it works fine.

I remember the first time I tried the old formula Tap Magic with the 1,1,1 trichloroethane. That stuff was amazing. I still have fantasies of finding an NOS can or two, heh.

trichloroethane, trichloroethene, trichloroethylene?

anyway, i worder what there is to it, as they are good solvents/degreasers. i assume they were the carrier for another substance that facilitates the cutting. so maybe no mourning over it neccessary?
