181. Re: [TowerTalk] Thrust bearing re-grease (score: 1)

Interesting ... so there is no manufacturer's recommendation to either grease or not to grease a TB-3/TB-4. So how did this do not grease recommendation come about? Surely not an old wives tale. Doug

Where is it written that a self-supporting tower has to be guyed with the same tension as a guyed tower? Why can't the guys on a self-supporting tower have no to little tension? Think about it. Those

Well doesn't that just go opposite to my experience. I have used TB-3 s to bear vertical loads for years without any failure. Obviously Rohn doesn't know that their bearings can bear vertical loads.

IMO the over rotation system on this rotor has little benefit with the stock controller. I remove it from my HDR-300s. The benefit in removing the over rotation is that the range of rotation can be i

And if you really want confusing facts, the Delhi/Taco self supporting DMX - 68' in Canada specifies approximate (their wording) base widths of 46" x 48" deep bell bottom base. Soil type is omitted.

Nope... real life experience is an anecdote, not engineering data. It predicts only the past for that one case. There's no way that anecdote trumps analysis, particularly if the analysis is based on

According to your figures, Rohn specifies a much larger tower base (5'9"x 5'9"x4') than does Delhi (46" x 46" x 48" deep bell bottom base) for essentially the SAME tower. So who is right? Doug I'll r
