I have now laser cut several copies of the two small plywood boat toys, with some success but still needing work.Making the decks slightly curved has had the desired effect of adding stability, but, it has made assembly more difficult.  The result is that I need to modify the designs to improve the ease of assembly, reduce the press-out ‘bridges’ (these hold the pieces in their cur board until pressed, like print bridges in a paper stencil), and improve the ‘fit’ especially in the RoRo.  I want very much to finish with these and move on, but it is not proving so simple.
