I manufacture tooling for the foundry industry. Mostly prop style pumps and enclosed impellers, volutes and split pump casings. This design took about 3 hours.

I also design molds for other customers, wax injection tooling for the lost wax casting process, and plastic injection tooling. Considerations need to be made in the design for parting of the tooling depending on the type of manufacturing process needed. Many designs have no clue what this means.

You seem to understand the concept very well. How long did it take you to produce this drawing?
