I tried an old Lard Oil recipe for cutting steel....

Bacon grease has some residual salt in it from the curing process so make sure to clean the part thoroughly after using bacon grease to prevent corrosion.

Good point

I’d like to see a comparison between Anchor Lube and lard. My guess is that’s it’s pretty close performance wise. The smoke from lard is a big negative IMO.

I use tap magic mainly because it works and it’s convenient. But I hate getting the **** on my hands.

Fog busters are probably the best overall option but the cheap one I use is bad about atomizing coolant and stinking the place up. I’m going to build a nice one soon.

One thing to note, lard contains "lard oil", or oelic acid, but lard is not lard oil, it contains stearic acid and other things. You can separate the oelic acid by melting lard with, say, a lesser amount of mineral spirits, maybe 3 to 1; let it sit for maybe a couple of days until the stearic acid, which has no value to us, separates and floats to the surface as a white waxy substance. Remove it and what is left is "lard oil" mixed with solvent. Works a treat on steel, and when mixed with beeswax, makes a nice steel tapping compound. Old school, but played an important part in WWII production, when civilians were asked to save "fats" for the war effort, and they were made into cutting compounds.

I like to use rendered fat or used fryer oil. The latter can be mixed with some dishwashing detergent to make a poor man's soluble oil. I also have dark sulphurized oil, cool tool and tap magic. The commercial ones work better, but the difference is not as much as that between a good tap and a bad tap. A bad tap is challenged on steel almost no matter what cutting fluid you use.

The last sentence says it all.

Of little or no value other than I always thought this was a cool picture and was waiting for an excuse to cue it up....

Hi, when I worked, we in the elevator industry drilled and tapped all day long. The go to lube was the can of Crisco, and if it wasn't handy as gross as it sound saliva was the next best lube. Charlie.

Yep, a lot of drilling and tapping especially installing bi-parting freight doors. Chewing tobacco juice worked in a bind also.

I don't think any other trade drilled and hand tapped more 10x32 to 58x11 threads then us on a daily basis, did it for over 38 years. Charlie

As a side note, if you want to render fat and make your own lard for cooking use leaf fat.
