As you saw in the last post I can inlay the mosaic pieces along with the veneer lines into the channel in the top in one step.  However, the rosette on the Torres guitar I copy has a lot more lines, mother-of-pearl and some herringbone which needs to be placed so the “arrows” meet on the centre line of the top.  Years ago when I was having trouble with a wide rosette Rafael Moreno told me about the technique of glueing the rosette into a different piece of wood and then cutting it out and inlaying into the top.  From there to using plexiglass was a short step.  The problems I was having at the time were due to the swelling of the rosette with the glue and the more lines there are the bigger the problem.  So I take the herringbone out of the set of veneer strips that you see above and replace it with plastic spacers which don’t stick to the wood and glue the whole rosette into the plexiglass just as if it were the top.  Glueing in the herringbone is then a simple task once the glue is dry and I can put it exactly where I want it.  Once again I think that Torres (and other builders) must have done something similar because otherwise how can you get the two herringbone points to meet exactly at one of the mother-of-pearl rectangles?
