For the past few months, I have been building an orrery. It is a comission... just shipped it off to Minneapolis. The new owner has made a very pretty web page for it

This has been the main result of my recent acquisition of a CNC Taig micro mill with 4 axes.

One turn of the crank is a fortnight.

Sarah Moore made a video!

 
     

 

 

     
 

The 6 planets and sun and moon are made of glazed porcelain. Shown below is earth, moon and mars.

 
     
     
 

The gears are bronze. I cast the blanks first, cleaned them up in the lathe, and the little milling machine did the rest.

 
     
     
 

The main shaft of the moon drive train rides on 4 sealed bearings.

At present, I don't even use CAD software. All G-code was generated by my own C++ programs.
