UCA bolts stuck rant

We get lots of rain, snow, cold here. The original cables were plastic covered, which cracks with use. I'm convinced the failure of one cable was due to internal corrosion. I had new ones made, and grease them heavily.

Winter before last, this was the project "rod knockin" mini whale (Dakota) sat on the hoist most of the winter.
