Book Scanner progress Jan 27

The Book Scanner project is moving slowly, but moving nonetheless. Pictured below is the lower frame and the beginnings of the collapsible pivot mechanisms. The lower frame is held together with four 5/16-18 bolts and the specialized washers used for assembly of this extrusion. The plate seen in the lower left of the image is .25″ thick aluminum and will be the lower pivot attachment point The two rounded blocks on the end of the single length of extrusion are 1.5″ x 1.5″ aluminum and will make up the pivot blocks and upright arms. Not shown are bronze bearings and shoulder bolts that will attach everything together.
