[TowerTalk] clamp on trhust bearing

[Patrick Greenlee]

Jorge, amigo, sorry but I can't recommend a two part bearing to use 
without the grand hassle of pulling the mast. You might be able to 
"surround" your mast with "rollers." You will need at least 3 rollers 
(wheels with their own bearings) arranged at 120 degree intervals.  If 
it were me, I would go for two levels of 3 rollers per level to 
distribute the force such as you would avoid denting or crushing the 
mast due to sharply concentrated force at the contact areas.  I would 
recommend considering placing a section of telescopic fitting tubing to 
strengthen the mast at the points of contacts with the rollers.  This 
reinforcement would have to be split into two pieces to be put onto the 
mast for the same reason you can't just easily swap out your failed 
bearing assembly.

Other that something along the lines of the above, I have no clue how to 
avoid the major pain of taking it all apart.

Good luck amigo,
