Very nice documentation project. I could almost feel the wind in my hair and the rain on my face, not to mention that slippery foot feeling while climbing wet metal and hanging on just a little too tight :-)
PS. I'm glad I re-read this post for spelling errors. I spelled feel as fell and no one needs to relive any memory that that little mistake may have conjured up ;-) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Kunze Sent: Tuesday, November 04, 2003 7:29 PM To: [EMAIL PROTECTED] Subject: Re: [smartBridges] OT: AP tower To clarify, that www.do-it-yourself-tower.com site was a fully engineered installation. I simply did the construction project myself. However, there were multiple inspections along the way and it was not a trivial undertaking. I actually added a bit of over-design myself. The tower is a 150' Rohn SSV purchased new from Rohn, complete with CA stamped engineering drawings. Every aspect was engineered by Rohn. I am very happy with the end result. Now if I can only figure out a way to keep the birds from "dropping" all over my building . . . Don't attempt to do such a project without doing your homework. Your building codes and limits will be dependent on where you're going to erect the tower. Check with your local building inspector. Hope he likes you. ;) Rk At 03:22 PM 11/4/2003, you wrote: >Johns disclaimer at the beginning of the PDF is quite important... not >due to code, but due to liability.
