[TowerTalk] How to disassemble a boom?

[Fred Sanborn]

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 
appreciatethis. 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 thecontrol 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 
automatictransmission fluid and acetone. Note this "home brew" released 
bolts betterthan any commercial product in this one particular test.Our 
local machinist group mixed up a batch and we all now use it withequally 
good results.
Note also that "Liquid Wrench" is almost as good as "Kroil" for about 
20% ofthe price!Steve from Godwin-Singer says that the ATF*-Acetone mix 
is best, but you canalso use ATF* and lacquer thinner in a 50-50 mix.
*Automatic Transmission fluid
