Hi Gene,

These are extremely stout towers that stay up under rediculous overloads.

I had a BX40, much weaker than the HDBX series, with a TH3 on it.  No problems.
A friend has an HBX56 with KLM34XA, also no problems.

The only BX type tower I have known to fall was a guyed one.  But it was
rediculously overloaded, and extended to 80 or 90 feet with straight 
sections that Rohn used to sell.

I have not personally seen missing rivets on these towers.

Get an old pair of workshoes.  The sides of the shoes will quickly become 
torn.  You won't have has much a problem as I had on my BX since your 
sections are much bigger.
