Thanks for the help. I actually used to be a welder. Welding is a great solution, but this would be a tough one. The aluminum is all painted. The rim is backed and flush with concrete (if that makes sense to you).
The owner would like me to rewire the power to the pool pump house, but not do the bonding. They called the pool installer and building department and were assured that it was properly bonded when installed (this isn't a recent installation). I tried to explain that a properly bonded pool wouldn't give varying voltage readings between the ladders and different parts of the rim.
I also have a situation of neutral/ground bonding I posted in the code section I could use help with. I don't know if it's related to the pool situation or not.
Thanks,
Dave
