Hi Joe,

If you really want to run a mast all the way to the bottom of the tower I'd
go find a used thrust bearing (the kind that's designed to support both
axial and radial loads) at the junkyard for it to set on and use a rotor
shelf, which you can use later when you get a real rotor, to secure it to
the bottom of the tower.  That steel ball sounds a little hokey to me.
You'll need to design some sort of decent brake to keep it from wrapping up
your coax.  Why not just buy a decent rotor?  Can't add too much to the cost
of the project when you figure in all that extended mast stuff.

I have been thinking about setting up my rhon 45 tower and have been
dwelling a bit on the mast.
 I was thinking about having the mast go thru the tower all the way to
ground level and placing the rotor there.
 I was also thinking about placing a big steel ball of somekind in the
bottom of the mast that would rest in a divot at the towers base. That would
take a lot of the weight load off of the Thrust Bearings.

 What do you think?
