Just two pictures of the start of the barge winch system. This will be the winch mounted on the dock. I plan to string a cable (string) continuous around the drum to a pulley at each end of the dock. I plan to install 2-4 shackles on the barge side of the line that can be hooked to the barges easily. This particular drum is made using two parts of brass tube and two fender washers.
Going to hook this one up using two push button switches and use a couple nimh or nicad cells to run it.
I'm hoping I can install a spring so e where on the line and friction on the drum with about one wrap, have to see if that works out.
