We reviewed the stage models for the grand challenge.

Two errors were noted: (i) the pockets on the Stage 1 model are too 
deep; and (ii) the Stage 2 model has five axis faces.

In addition we may want to change the stage 1 model to remove more 
material from the top half because the top wall is lower than the bottom 
wall.

We discussed the tooling and suggested we may want to include a basic 
solution that uses a minimum number of commonly available tools, and an 
advanced solution that uses the best available tools.

The basic solution will then be easily available for those who want to 
reproduce our results, while the advance solutions will show the 
advantages of using better machines.

We have now moved to a weekly schedule so the next call will be at the 
regular times on April 18.
