Doug,
My wife and I have taught 65-70 10-16 year olds in woodturning classes a Maryland Hall in Annapolis.
Treat the students like little league. you're not training them for the Majors.
You are exposing them to a wonderful way to make something creative.
Keep classes to 3 hour sessions. Each class should result in a finished piece.
Be success oriented.
Spinning tops are a great first class. They can't make a top that won't spin
an instructor finger on the gouge when they turn the handle will make it smooth for those having a bit of trouble.
They can't make a gavel thet won't hit.
Make a wooden model of the gouge so they can see how to roll the bevel on the wood to present the cutting edge.
keep things simple. tool on the tool rest, bevel on the wood, roll into the cut.
We avoid using chucks with kids. many projects are done between centers others on faceplates and wooden morse tapers work great. The older students can turn their own. Stick with 4 tools spindel gouge, parting tool, roughing gouge, chatter tool.
Our list of projects with dimesions can be found on our web site.
