Thanks for the response. I like flood lights especially for operating accessories and cars in low light. Just figured out I need to add more light around the gantry crane to see where we are dropping canisters in gondolas.
Working on the automated log loader got me looking in to the coal mine dumping system. Recently (Sept 2017) the log loader was not dumping. Turns out a plot of piston distance from the magnet shows the most pulling power is when the piston is 1/16 to 1/8 inch out. The piston was much more out from the magnet so I had to modify by adding about 1/16 inch wood to the sloped part to make the trigger pull when about 1/16 inch out. That fixed it.
