view of the inside of the front, showing the carry bearing for the crank handle. under the plywood, between the cleats, is a chunk of rock maple, about 3.5 inches cubed, with the curve of the trailer front cutting away just under half of the cube. the hole in the maple was machined on a cnc milling machine, is just slightly over sized for the crank. 

btw, thus is un unfinished storage space, hence the glue drips and rough cuts. don't have time to be neat in there.
