I built a dummy load consisting of 4 x 200 ohm globars in parallel.  Each 
resistor is 12 inchs long x 1 inch OD. 
Each resistor resides in its own 3 inch od x 12 inch long AL pipe.  All  4 x AL 
pipes are heliarc welded  together. 
The entire mess will sit in a 7 gal new paint can.    A 5 gal can + top part of 
a 2nd can were brazed together.  
A 7-16 DIN was installed dead center in the top lid....along with a pressure 
relief tube, off to one side.
Instead  of xfmr oil,  can distilled  water be used instead ??    It will only 
be used on 160-10m..and maybe 6m.

If something goes terribly wrong, Id rather have water all over the basement 
floor  vs oil.   Distilled water is
an insulator.   Heck, Bird + CD have water loads that use tap water.  AG6K 
depicts a hb water load...with a 
single 500W resistor inside some pvc tube and a garden hose fitting on one 
end....and  coax connector on the
other end.  

I realize water boils at 212 F.   Has anybody tried distilled water in a 1 gal 
dummy load ?  Is it still 50 ohms ?
