: How are you getting your edge to edge pressure? I understand your
: are getting flat downward pressure.

: I was involved in guitar making years back and we used to put a
: pencil under the seam raising it and then drive nails touching
: the outside edges. Apply glue to the seam edges, pull out the
: pencils and press down and you get good edge to edge pressure.

There is not a lot of edge to edge pressure, only what you get from wrapping the string. Ergo, the pieces need to be accurately jointed. When you are dealing with 24" long pieces, you can joint them with a block plane. In this picture there are eight pieces being glued up at one time and the panel came out nice, with minimal sanding. It has been about 20 years since I last used this technique. (Also, I am neither Spanish, nor a luthier. ;)
