Re: Concrete pier

Nick Iversen

I don't have any experience with pole piers. But for a Mach1 and 130mm refractor I can't image them flexing much. I should go and observe some telephone poles in the wind. But vibration - why do you think a pole would vibrate? What frequencies? I have a wooden Berlebach tripod which is made of much less wood than a pole. I can't image a pole being less steady than that.
