This is a nice introduction to foundry and lathe work. It introduces simple concepts in foundry, lathe work and lathe based milling. It will take a junior student around 7 days to complete and makes a nice addition to any tool box.
This project is broken in to three parts. First is the student work book which describes the process for making the hammer. the second is how to make the split pattern used to make the casting pattern. The third explains how to make a foundry flask.
