Loosening Rusted Parts.


Got this from my step-son this morning and thought it was worth sharing.

Machinists Workshop recently published information on various penetrating oils. The magazine reports they tested these products for break out torque on rusted nuts and bolts. A subjective test was made of popular penetrating oils, with the unit of merit being the torque required to remove the nut from a scientifically rusted bolt.  Average torque load to loosen nut:

No Oil used 516 foot pounds
WD-40 ..238 foot pounds
PB Blaster .214 foot pounds
Liquid Wrench .127 foot pounds
Kano Kroil .106 foot pounds
ATF/Acetone mix. 53 foot pounds
The ATF/Acetone mix is a home brew mix of 50/50 automatic transmission fluid and acetone. Note this home brew released bolts better than anycommercial product in this one particular test.
Our local machinist group mixed up a batch, and we all now use it with equally good results. Note also that Liquid Wrench is almost as good as Kroil for 20% of the price. ATF/Acetone mix is best, but you can also use ATF and lacquer thinner in a50/50 mix. ATF = Any type of Automatic Transmission Fluid.

This version of the story was in one of the Military Vehicle Club newsletters

Don't know what the side effects might be, Amigo, but I can almost gaaroontee that Constipation would not be your biggest concern.

 No doubt.

I have used some variation of that formula  or another for most of my life as a wrench turner.  A guy gave me a Winchester model 94 rifle once that was so dirty and rusty that before I even set a screwdriver to it except for taking the butt stock off and the forearm wood, I filled a five gallon bucket  with a gallon of ATF, a gallon of acetone, a gallon of diesel, and a gallon of Marvels Mystery Oil.  Then I stuck the action end of that gun in there and let it soak for a couple of weeks; then I started "working" it a bit every day and putting it back in the bucket.  The barrel was so crudded up that I couldn't even poke a cleaning rod through it, so I poured as much of the mixture as I could get into the muzzle end and let it soak a bit then would get in there with a dental pick and dig as much loose as I could, and set it to soaking again.  Eventually, it all came ungummed, and after I got it apart and cleaned up, the only scars it has are some pitting.  All of the parts cleaned up with just ScotchBrite and polish, and I didn't even have to work them on a stone.  Now, that is a gun with some character.

Em(I), if it had been a Marlin, would you have gone to that much trouble? nobiggrin  Did you ever fire it after the cleaning?

YES, and yes. Not a bad shooter. It's in 38-55 Winchester, and one of five Model 94 (full length) rifles I have, one in each of the five original chamberings they came out in, and the newest one was manufactured in 1908. As to Marlins, I do like my Marlins, too, have several in a few different calibers, and I would have gone to the same lengths for one of them, as well as probably most any gun, especially old ones. When I was active in Cowboy Action shooting, my main match rifles and carbines were Marlin 1894s and Rossi 92s, a repop of the Winchester 1892, in .357 and .44-40W, and one reproduction Henry 1860 in .44-40W.

Way cool, I've always wanted a Winchester Lever Action in the .357 caliber but when I got the big "D" I sold my Winchester collection to my good friend and kinda got out of the hobby so to speak. I've also given all of my long guns to my boys and am down to a Tarus Revolver for Home Defense.no
