Hey Gang,
Reading the Nth thread on lubing thrust bearings, and just had a thought - 
would it be a good idea to design a thrust bearing that works based upon an 
'ultra high molecularly weight filled self lubricating plastic" (aka something 
like a filled teflon - or rulon or even vespel) - nothing to ever 
rust/lubricate, and they can take decades of low to medium speed 
rotation/sliding - heck, in theory, if your mast was truly round, you could 
just have 3 or 4 pressure blocks, and it just rides on that

BTW, for that matter, if you could assure it stays WET (not dry, WET), I'd bet 
a lignum Vitae bearing would be about perfect for a tower thrust bearing
