i agree with the farrier teacher. A lot of people don't like to start small. The beginner classes i have taught we start out learning anvil comfort and hammering properly is shown. Hammering properly is very important and the students are continually reminded throughout the classes, because it is very important and we all have to be reminded until it becomes second nature. Then you teach to round something square, then take it to a point. The second day get them to design something with what they have learned, i have had surprising results that way. With that you can build a simple set of tongs. That takes in drawing, rounding, tool design and riveting. Very simple exercises and valuable. As you teach them the basic skills get them to build the tools to make what they are designing and it is much more rewarding and when they go home it is a lot easier for them to build new stuff and tooling up for a job is learned right from the start.
And on and on it can go from here. This course design can be 2 days or 2 weeks, what ever you have planned.
