Abstract
AbstractAn accelerated method for the production of wax plate models from serial sections is described. Serial sections are projected on the back of 1 mm wax plates and the sharp image produced on the front of the plate is cut out directly with a knife. The construction of a simple projection apparatus which permits back‐lighted projection is described and illustrated. The apparatus is built of common‐size lumber and a small sheet of Plexiglas. It consists of a screen for the image and a wooden track on which a light source and microscope can be moved back and forth for different magnifications. Commercially available wax plates can be used. A method and the equipment needed to produce larger plates are described.The cut‐out images when piled up to form the model are welded together and strengthened by inserting heated straight pins. The exterior of the model is smoothed with an electrically heated glass instrument which provides constant heat of desired temperatures. The construction of the glass instrument is illustrated.
