Hi Grant,
I am also interested in your concept of a UV resistant UHMW radial top bearing.
I am part of a team that is building a station in the Caribbean, and am
considering trying a non-metal bearing approach. Do you have a sketch or
drawing that you might share?

Grant,
I'm curious about this. Some questions:
- How did you drill the hole for the mast?
- How much oversize? I imagine its not very critical, is that true?
- Is any particular color better with respect to UV and other environmental
exposures?
Thanks, and 73.
