[TowerTalk] Rotor replacement

[Phil - KB9CRY]

I'd like to just reiterate that it doesn't matter how many thrust 
bearings one has on the mast, those centering screws are not meant to 
hold any of the vertical loads of the mast/antenna assembly.  They are 
only meant to center the mast in the bearing and other external means 
must be applied to transfer the load from the mast to the bearing.  Many 
may have been lucky using the screws to hold the load but it's your 
fingers.  For me, I purchase stainless steel pipe clamps from McMaster 
Carr and attach these to the mast and let this ride on top of the 
bearing.  Don't use regular muffler clamps as these will rust into an 
unsightly mess.  Phil  KB9CRY
