re: Himitsu-Bako ("Japanese") Puzzle Box.

Very interesting box - the hokone puzzel boxes are amazing.  I cheated and bought some kits which I veneered and glued together.  After doing a few I found that it was very important to make sure surfaces to be glued were sanded flat, and the to use plenty of preasure when gluing up.  Failure to do this resulted in glue lines and a sloppy fit.
