Tracing the top and back

The linings have been glued to the ribs (below right).

The top and back pieces started as rectangular pieces of solid maple and spruce. Each is made of two halves glued together. These are called ‘”blanks”. I traced the outline of the ribs on the top and back blanks using a 3mm spacer, and cut them out on the bandsaw (below left).ribs-top-back
