[TowerTalk] My 48' Delhi Self Supporter folded over :-( lost its bolts!

Mike,

It almost sounds like they were not tightened down to the correct torque to
begin with because they should not have come loose with lock washers.  I
would get new nuts, bolts and lock washers and torque them correctly and
double nut the bolts.

Hi Guys,

Mike VE9AA here.
My 48' Delhi Self Supporter folded over a couple days ago .....

As far as I can tell, the reason this happened is 2 large bolts (with lock 
washers) backed themselves out and there were only 2 remaining legs holding 
it up.  We had some wicked wind up here on the hill the other night, and 
poof, it's was over.

Has anyone else heard tell of this happening to any other Delhi towers? (or 
'similar' self supporting flat-stock towers like a Titan, etc.)

After the fact, I heard that VE1DX had the exact same thing happen to him.

What can I do to prevent this in the future please? Red Loctite? Tighten 
bolts yearly? Other?

73/TNX, Mike VE9AA
