Re: [RE-wrenches] Racks, wind
Also, gotta say Jeff is building very high quality TOP racks. We've installed 7-8 of them since his "departure" from DPW, now Preformed Line Products. Welds, materials, powder coating are top notch. Right at first, as you can imagine getting started again, there were a couple small details that were a little wonky but they seem to have it wired now. Ship times might be a little better too. William, curious how old some of the wind ravaged racks are? I haven't seen that 2X2" material being used for awhile on a rack that size. I used to have some problems with snow when they were using that 2X2" square steel tubing...that was several years ago, like 10?

Re: [RE-wrenches] Solar World Wind Damage
William, Looking closely at your picture of the rack failure with the tower in the background, it looks like there is some discoloration/staining/rust? at the main spar center bolt. I went back to some of my older installs to discover this happening and on a couple of them was able to rock the rack E-W more than I should have been able to. I think this was discussed on the list a ways back, you may be aware of it that that center bolt needs to be reefed on to prevent any movement. If the hole in that main spar was compromised and the rack was able to shift back and forth...not sure if that would contribute to failure of the kind you experienced.

Re: [RE-wrenches] Solar World Wind Damage
Bill; Great point, I have had the exact same trouble not being able to torque that center bolt down. I went back on a DP&W rack that was rocking E-W as you described, and brought a big socket (1-1/16"?) and my new Milwaukee 1/2" impact driver. It only took a 1/4 turn more, but what a difference: completely tight. I don't know what the torque spec on that bolt is, but its obviously more than I can do with regular wrenches. My Pocket Ref shows 257 ft-lbs for a 3/4" bolt. I'm suspecting that might be part of the trouble on the rack that I just reported module failure on. If that rack can start rocking back and forth in high wind, it can really cause damage.
