[HCARC] For your rusted "tower nuts.".

[W4wj at aol.com]

For stainless, it is best to start with NoAlOx on all
your stainless hardware  to prevent the stainless 
from galling and seizing.
 
Over time the stainless will be easier to "unbolt."

I've had  problems with stainless hardware as well.
What's good for  that?

Saw this post on the 599 DX Association  Reflector - might come in hand for
those rusty tower bolts.

BTW,  this is Lew King, W5LEW, K5GIT's brother-in-law, who was hanging out
some  at McDonald's with the HCARC Wednesday morning gang this past Fall.
I'm  over in Mississippi in the motorhome for the winter and will be
WorKamping  again this summer in Colorado.  However, I'll be back in
Kerrville  briefly in late April and will try to pop in at McDonald's to
catch up on  you guys.  We were also in that 16 mile wide monster hail-storm
here  in the Jackson, MS area that made the national news last week -  had
baseball and softball size hail here in my RV park!  Damaged both  motorhome
and van - the van got the worst damage with a shattered  windshield - it's
estimated that 10,000 homes and vehicles were damaged in  the Jackson area.

"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. This was in one
of the Military Vehicle Club newsletters  >>
