Hi Clint --
Nice that you were able to get that rotator repair info 
in a pdf file.  Perhaps the author of that one would 
also put it on a web site to make it easily available to 
others.  If he needs the space I can add it to my info 
and give him full credit.  I just wanted to make sure 
this kind of information was made available to other 
hams.  Several things on my website came about 
because I couldn't find any good info out on the web 
so I had to wring it out myself.  Then I wrote it up for 

I absolutely agree with you about not using gasoline 
for a cleaner and I knew I'd catch flack from 
someone if I let that go on into the article.  The truth 
is, however, that I told just what I did during my 
repairs and I did caution about using it outside and in 
the clear.  If I was really smart I wouldn't have used 
gasoline either, but if I were really smart I'd be rich 
so I guess you see that I'm admitting to 
Next time I rebuild one of my rotors, I promise I'll 
plan a bit further ahead and have a much safer 
cleaner on site.

I've already received several notes from other guys 
saying that they were glad to see this information so 
my time in preparing it was worthwhile and well
