Current budget is $250,000 but will be trimmed in time :) I LOVE my 
sponsors!

This is true. But how do we mount a scaffold lift on the side of a coil? 
This won't be easy.

hmmmmm...any ideas? What other than ACSR would be good? Size?

Look at a topographical map of the area. It's very weird, big hills on one

I LOVE being in this line of work :) Perhaps I will build a little version,
