I'm in the keep it tight category - why have a thrust bearing if it doesn't
secure the mast? I'd be concerned about scoring the mast and weakening it
over time if there is a small gap. Cheers, Joe WDØM At 11:49 AM 7/22/2004, Noel wrote: Agreed with everthing except the statement. "...Then make sure the collar can rotate around the mast without binding".. Seems to defeat the point of having a thrust bearing? Why not have just a collar then? I think the bolts in the thrust bearing should be tightly holding the mast or at least very snug. Not bearing weight but enough to support any lateral movement. Your method would cause the bolts to eventually scar the mast even though you say the clearance is minimal, unless one used shims. _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
