: In theory you could carve it all from a solid chunk of wood just
: like the minicell seats. That would waste a lot of lumber. So
: you use laminations to remove the bulk of the material. Then
: carve it to shape and then skin it with a layer of glass on each
: side. The edges of the laminations help guide you during the
: carving. The patterns for mine come off a 3D model.

: For the first one I used horizontal laminations. It worked OK...

: A CNC router would make this a LOT easier! :)
Dan, You don't need to go to the expense of a CNC system. You can build a duplicator system for your router (think key making machine). I saw one in New Hampshire at a Windsor Chair shop. Quite basic. To create your pattern find a tractor seat and make a negative mould of the top surface,then make a positive mould from that. This will be your pattern for use with the duplicator. This should work well with either a block of wood or a glue up as you use. The duplicator has applications for any number of projects where multiple copies will be needed.
