This CAD screen capture, which looks like a big black blob, is in fact he CAD drawing of the mechanical bits of the current Rat Philharmonic piece with out the handle shown. A lot of hours are spent fussing to get things lined up correctly with a project with as much component density as this. The rats are not shown in this view as I do not tend to draw them with CAD but rather use hand drawings and carve from there. The chair bases on top are just placeholders for where to drill the holes in the top plate for the chair legs.
There are always a few "fit in field" elements to work out once building starts. In this case the hole locations for the foot linkages in the top late will be checked before drilling even though they are shown in the drawing.
I expect to be back in the shop tomorrow afternoon making sawdust and hopefully useable components to start the final assembly. I am trying to complete this piece for the upcoming Belleville show.
Oh yes if you are wondering it is done in TurboCad for Mac!
Automata is a creative blend of my life interests , engineering, art and woodworking.
