Best penetrating oil is cheapest

[4wdtom]

AFAIAC pentrating oil works only on exposed treads as it softens the rust up and helps lubricate while removing,it might creep in a fraction between the nuts and treads but thats it.
I never had a nut come off or a pin come out after using whatever brand of penetrating oil that had the stuff completely soak trough the length of the nut or pin unless one works the nut or pin back and forth for some time while adding fluid..
On a pressed in part pen oil helps only to lubricate the exposed end as it is pressed trough as there is no way for fluid to creep in were there is no gap between the parts.

Agree with you, unless there is movement or space for the oil (of whatever brand or mix you are using) to get in it won't do a thing.

Brad, why would I watch MSNBC when Fox is more entertaining than a Three Stooges marathon? (Not quite as cerebral, though. The Stooges could say dumb things in Pig Latin.)

I watch both, I like to know what both extremes are thinking.

A 12+ year old thread makes a comeback! In 2014 it only took 10 responses for a penetrating oil thread to be turned political. The wild days of YT!

Semi-truck lug nuts are torqued to ~460 lb/ft,

The study wasn't using foot pounds on a fastener. It was using pounds of force required to push a rusted pin out of a hole. Pins were put into holes, then chemically rusted into place. The pins were pressed out of the holes and force required to press them out after using the various panther p1sses was recorded.

My point was that some years ago I really did search the internet for the almost mythical research . I just couldn't find it despite a really concerted effort . I'm not saying it doesn't exist just because I couldn't find it , perhaps it does , but , like all things unsubstantiated on the net it needs some healthy doubt .

At the time I was first presented with this, it came with a working link to the original source. That source was named in your link, but now I can't even get the page in your link to load again

In any event, I had the opportunity to read the original full presentation.

As far as the poster on page one calling me dim, I am willing to forgive and forget since he had the excellent taste to choose his user ID from the title of my favorite Pink Floyd song.

"Arnold Layne" is a song by English rock band Pink Floyd. Released on 10 March 1967, it was the band's first single and was written by Syd Barrett.

The song is about a man whose strange hobby is stealing women's nnalert from washing lines. According to Roger Waters, "Arnold Layne" was actually based on a real person: "Both my mother and Syd's mother had students as lodgers because there was a girls' college up the road so there were constantly great lines of bras and knickers on our washing lines and 'Arnold' or whoever he was, had bits off our washing lines."

The me, if trying to free something acetylene is better in that it gives a hotter, faster, more concentrated heat than propane. The concentrated heat is why it is used for gas welding. That said oxy/propane is better than the hand help "Mapp" and propane cylinder torches. YMMV

Actually, my biggest concern is cutting mild steel. I have several old 275 (?) gallon fuel oil tanks I want to cut up. When you cut the ends off, and leave 4 to 6 inches of the curve at the top and bottom of the long flats, they make outstanding skids. Hook a chain into the two leg brackets, and off you go. The curve does an excellent job of preventing snagging as it pulls across the ground. The only catch is, don't try to pull one through the woods. Don't ask me how I know

I want to make a pair of half width ones for myself, and then give the rest away as party favors. The idea of using a cutting wheel or sawzall and then cleaning up the razor-sharp edges I've just created doesn't appeal to me. Will oxy/propane do this cutting?

Glad I'm not the only one to have read the whole presentation. Your memory is better than mine, I didn't remember it was pins not nuts or bolts.

I well remember reading the article 19 years ago. A google search brings up a bunch of posts saying it was torque required to loosen a nut on a bolt but the original article explained how they used a process to rust pins into holes then measure force to break them loose with a press. I was unable to link to the original article, it seems to have disappeared over the years. One place said the article is available if you buy a back issue of the magazine that published it. The story of the study has been retold for nearly 20 years and like any retold story, the details have been altered over the years!

yeh an for the hole crew in dc -from the president on down

This has to be the funniest part of this whole thread. 4 people gave thumbs up or lovey eyes to this post. Remember this post was made in 2014, so...

That is not what the study says in that link in reply #36. If it was a pin rusted in a hole, I wonder how that relates to our world?

Well, that's what the study was. I read it first hand. It had nothing to do with nuts and bolts. It was designed to see how well each squirrel p1ss would break the bond of rust between parts. The easier the pin broke free, the better the penetrant broke the bond of rust, or so it was implied. The pressure required to break the pin loose was monitored with a psi gauge on a hydraulic press. The article also stated that it wasn't a strict scientifically controlled study. I've seen the story in the link. It is a second hand retelling, with inaccuracies, of the original article from the machinist magazine.

Here is the article as I read it 19 years ago.
