[TowerTalk] aircraft bearing

[Michael J. Castellano]

I'll go with John W0UN on this one. 

Been using a piece of lignum vitae (sp?) for years on a Telex LP-1002 log periodic. last inspection indicates I'll only get around another 50 years life out of it at the crazy rotation speed of 1 rpm!

lignum vitae is what they used to make bowling balls out of back in the old days...not sure what they use now.
 
I'll bet a nice piece of mahagony would work just as well, its hard and stable (won't warp).
