Re:  Transformer Oil in a Cantenna.

In the interest of Environmental  Security, please don't repeat my comments 
!

In my mind, philosophy and  experience, xrmer oil PCBs, asbestos tile, 
tefelon, and other items',  "scares" and "alerts"  are just a bunch of 
unproven malarkey, as long  as you don't drink, eat or breath them in, 
for sustained periods.  A  lot of money has been made trying to 
correct these myths.

Years ago  (over 55), I made my first really HV power supply using a 
surplus   power company "Power Pig".  In order to retrieve the desired  
transformer, I had to insert my hands, arms and wrenches down into 
the  Pigs's oil to unscrew the retaining bolts.  After draining the  
remaining oil into a small depression in my back yard, I then baked  
the xfrmr in the hot AZ sun for several months, and got rid of 95 % 
of  the still saturated oil, before I installed the xfrmr into the 
PS.   In my military and aerospace carriers, I was exposed daily to  
asbestos wall and floor tiling.  In fact our company once had a large  
contract to carefully remove it (using hazemat equipment and attire),  
from numerous AF satellite tracking stations. These experiences has  
not seemed to have diminished my capability to continue to pay my  
annual taxes !

Ron, I did fill my original Cantenna with Mineral  Oil, which seemed 
to work well over many years.  It was more easily  available than 
xfrmr oil, in spite of the druggist's funny looks.   However after a 
major spill of it (cat litter works well in soaking it  up), I 
replaced it with some modern Power Pig oil, that someone had given  me.

I would have no compulsions on draining a gallon of it in the back  
forty of your lot.  It will never reach the water table.  Even  our 
bleak desert soil has amazing filtering properties.   As the  saying 
goes for those who have been accosted by, and have had to dispose  of 
a  "threatened" species :  "Shoot, Shovel and Shut Up  !"

Mike,

I will be out of  town by the Christmas party so you and I may need to 
make some  pre-arrangement to cover the expenses of the party.    I 
will be  at Thursday's meeting and can collect payments.   I will be 
back  in Tucson by about January 10th.   If you want, we can estimate  
the costs and I will front you the money and we can do the detail  
settlement after I return.

You are  so right about getting rid of the PCB oil. Fortunately when I 
replaced my  original "transformer oil" I worked at the University of 
Utah and they had  a haz mat unit that took care of it for me. They 
came in with masks and  gloves hauled away my Heathkit Cantenna. A few 
days later they brought it  back, all clean and shiny. For me, it was 
easy, but I was  lucky.

The  original transformer oil is full of PCBs (polychlorinated 
biphenyls) and  getting rid of the stuff can be difficult. PCBs are 
carcinogens and have  been banned since about 1980. It is the best oil 
to use in a dummy load,  but don't let anyone know that you still have 
some (except the guys in the  DX club of course). I would keep it 
outside to avoid inhaling the  vapor.

[SADXA] dummy load oil??

Hi Ron,

I found my old Heath HN-31  1962 Cantenna Assembly Manual.. and on Pg. 
9 - Final Assembly -- it  states:

The recommended Transformer Oil may be obtained from most any  bulk 
oil plant.. If transformer oil is NOT available, mineral oil may be  
used, but do not use any type of Motor Oil. The Vaporizing 
Temperature  of Motor Oil is too low, and would cause excess vapor.

Looks like  Mineral Oil will work.  Be interesting to look up the 
Vaporizing  Temps.

My HN-31 still has the original Transformer Oil.. after 52  years, and 
has not leaked. Some vaporizing has occurred, ..since the oil  level 
is a bit low. Thus, I also should replace the oil.

Best  73s,

Bill Davis  W7EXG
