     Yeah, I didn't get everything in my head onto the paper.  I don't like 
     to trust a thrust bearing to support the weight alone without a 
     fail-safe backup.  I guess I shouldn't have used "designed" - that was 
     a real poor choice of words.  I do have a paranoia about the mast 
     clipping my toes.  Had one slip down a couple feet once.  Don't 
     remember all the details - the bottom was already lower than my feet 
     and no damage was done as I recall.

Well, Greg, if it is a Rohn thrust bearing, that is exactly what it is for: 
to hold the weight of the mast and antenna.
