Paul,
How do you think you would go with your new found skills in mould making, in doing the bell
housing you had previously designed. What is the minimum thickness your foundry will
accommodate?  You have suggested they will accommodate fairly thin wall sections for
non-injection type moulding.

Paul Lamar responded:

The big problem with doing a bell housing casting is the pattern is too large for the 3D
machine. I would have to pay big bucks to have the pattern made.  The foundry can do 0.140 wall
and I will soon have some parts with about that wall thickness.

Paul,
Could the pattern be made piece-wise from individual runs of the 3D machine?

You are a genius Russell. Either that or you can read my mind being 
2000 miles away. I was just thinking about that. It would, I think,
take six segments. Chrissi would love it.
