Just over a year later, my benchwork, track, electronics, and control
system are finally complete! This weekend I made the last adjustments to my
trackwork; soldering a few more connections and leveling out a few last
problem areas on the track. Both my Backmann EMD GP30 and my Kato SD-40
engines run perfectly on the layout and all aspects of the control panel and
electronics, including the dual-cab wiring, work perfectly.
I also added a handle to the winch that raises and lowers the control panel
so I no longer have to use a screwdriver as a lever. I also came up with a
latching system that will lock the control panel into place when it is in
its raised position. This prevents the winch cable from supporting the
weight of the control panel when raised and also makes the control panel
more rigid when in use.
To do this, I used two double ended bolts that I attached to the
underside of my benchwork. I then drilled two holes through the control
panel base so the protruding bolt end could pass through the control
panel base when it was raised up against the benchwork. I then used
butterfly bolts to support the control panel on these bolts.
To make locking as easy as possible, I cut slots in the holes that
I drilled, allowing the butterfly bolts to pass through the control
panel base. This prevents the butterfly nuts from having to be
completely undone. Once the butterfly bolt passes through the
control panel base, it is turned 90 degrees, allowing the entire
control panel to rest on the bolts (as seen above). Metal braces
were added to prevent the bolts from damaging the hardboard.
