Bob Morris “Teaching Blacksmithing”
Teaching students to make a Wizard Head
Teaching — Main principles
- Be prepared, a one hour class requires four hours preparation
- Motivate students to retain material taught
- Make a story board of steps in the process
- Teach how to make all the tools necessary
- Bring something to give students such as wizard heads drawings or handouts
- Bob likes two blacksmith books for basics;
Jack Andrews - New Edge of The Anvil
Randy McDaniels - The Blacksmiths Primer
- A fire tender takes the worry away about proper heating
