Also...if you are only planning on a single moderately-sized (i.e. not a 40m 
full sized) antenna immediately above a thrust bearing, I don't see anything 
wrong with using heavy-wall conduit for a mast. 

I use heavy-wall conduit from Lowes for masts on both of my towers. One has a 
Force 12 EF420/240, the other a 6 el 15m with 36' boom. Both are only an inch 
or so above the thrust bearings, with nothing stacked above them (ok, there is 
a TV antenna on one mast). Both have been through storms nearly up to our 70mph 
county windspeed.
