[Bmcu] Fw: Penetrating Oils]

[Ron Christensen]

Not included are the torque specs for British car nuts and bolts including that point at which the head strips or the bolt breaks resulting in the inevitable knuckle injury, at which point an application of 50% betadine, 30% alcohol and 20% hydrogen peroxide seems to work well.




Subject:  Penetrating Oils
 Interesting!  Even if you're not mechanically inclined, this might be worth
noting.

This story came to me from one of the guy's in the EAA club  Interesting !!

"Machinist's 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 any
commercial 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 a
50/50 mix.  ATF = Any type of Automatic Transmission Fluid
