Nice write-up at Lassen George. Just the way I remember it, except for the heat! Seems most days were at least 85* in the shop from noon until we shut down at 9PM.
If you weren't there you missed a good time, and I can't imagine there is a less expensive way to come up with a cannon. The classes, lodging, and materials are all reasonably priced, and the machinery and tooling use is free!
If this class is offered again next year, seriously consider attending, it's a bargain. If there is a continuing interest it seems more likely the school would be more willing to repeat it.
Thanks again George, I had a good time and ended up with a nice cannon.
