Re: Tri-Ex Disassembly...
I can drive around the corner and take a picture of a W-51 thats folded over in half. He didn't have it all the way up and only a KLM KT-34XA on it at the time.
A common problem with the TriEx towers is the crimped tower leg guides at the top and bottom and lack of a sufficient drain hole at the bottom. The legs fill with water and corrode from the inside out. Unfortunately these very crimps prevent the hot galvanizing liquid to get inside sufficiently. I usually will drill a small weep hole in them if the factory hole gets plugged up with metal flakes. Water usually comes pouring out. TriEx owners should take a wire and clean out those bottom holes!
I had one guy that wanted me to tram a 5-el 20M and a 3-el 40M with the tower cranked half way down to "clear the roof". I refused because of the water that came out of the legs. He got Hector to do it and I understand he wasn't excited to do it either.
With the amount of surface rust on the outside, I'd cut it up and scrap it. I just took down a 72' one in Granada Hills and cut it up. All the legs had water in them about half way up. I found out when the cutting wheel broke through.
Even if you get it apart, acid washed, and re-galvanized, the leg thickness may be compromised. Just keep that in mind when you load it up.

Well this one went in around 1975. You can see some of the crusty stuff in these shots. I'd just feel a lot better if everything was cleaned up, inspected, refurbished and put up for another 40+ years of service...
