Claims4
A method of forming a wood board picture puzzle, comprising the steps of:
- providing a wood board having a first surface separated from a second surface by a thickness, with a picture on said first surface;
- die cutting said wood board completely around said picture and completely through said thickness from said first surface to said second surface, thereby providing a die cut portion having said picture thereon and a frame defining an opening and surrounding the die cut portion;
- removing said die cut portion from said opening;
- attaching a back board to one side of said frame, thereby closing said opening from said one side;
- with said die cut portion removed from said opening, using a band saw such that said die cut portion is cut into multiple puzzle pieces;
- then
- inserting said multiple puzzle pieces into said opening from a side of said frame that is opposite said one side, whereby said multiple puzzle pieces are prevented by said back board from exiting said opening from said one side;
- and
- using a punch press such that a peripheral portion of said frame is removed and said frame attains its final configuration.
