[TowerTalk] thrust bearings

[Bryan Swadener]

That'd work. On my US Tower TX-472 in order to make an "umbrella" above the thrust bearing, I added a stepped plastic adapter, intended for use in wood shop dust collector systems. I bought it from the local Rockler store (http://www.rockler.com/dust-collection/dust-collection-fittings/universal-dust-adapter). I cut off the smaller steps, shimmed it to fit my 2" OD mast, and secured it to the mast using PVC tape.

I've seen guys take a 2" rubber ( plumbing) vent flange and slit it to go over the mast and slide it down over the TB3 bearing for additional weather protection. Either bearing, TB3 or the DXE, is a good product. My suggestion would be to periodically rotate the beam, especially during the slow DX season, and even park it in different directions. Don?t let it sit endlessly in one direction. I?ve had good luck exercising my rotators throughout the year. Hope this is helpful.
