[SFDXA] How to disassemble a boom? - Penetrating Oils

[Bill]

This was part of a thread on TowerTalk. Since I have a boom on the 
ground that I needed to separate, I thought the information might be 
interesting to others.

"Maybe now is a good time to post this information I have found useful
concerning penetrating liquids.  Maybe it will help with the boom
dis-assembly.

Machinist's Workshop MagT  published some information on various
penetrating oils that I found very interesting. Some of you might
appreciate this. The magazine reports the break out torque values on
rusted nuts using the tested penetrating oils.Results are below, as
forwarded by an ex-student and professional machinist.They arranged a
subjective test of all the popular penetrates with the control being the
torque required to remove the nut from a "scientificallyrusted"
environment.

*Penetrating oils ....Average torque load to loosen*
No Oil used .................. 516 pounds
WD-40 ........................... 238 pounds
PB Blaster .................... 214 pounds
Liquid Wrench ............ 127 pounds
Kano Kroil .................... 106 pounds
ATF*-Acetone mix......... 53 pounds

The ATF*-Acetone mix is a "home brew" mix of 50% - 50% by volume
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 about
20% of the price!Steve from Godwin-Singer says that the ATF*-Acetone mix
is best, but you can also use ATF* and lacquer thinner in a 50-50 mix.
*Automatic Transmission fluid'
