I have made several hand planes over the years and Tom mentioned to me that it might be a good class. Wooden hand planes can be finicky to tune but give much more joy in use since you created it. It would take 2 classes to complete but they are not hard to make and a joy to use after tuning. I made one last night to replace the first one I made 20 years ago. Each student would need to provide their own materials and we would make a traditional Krenov style smoother. I have always used Hock blades and plan or ordering a more few soon for myself, I want to make a high angle smoother for figured woods and another block plane.
The blades are the most expensive part at $40-$50 but well worth it. The wood is up to you but this is a good time to use something that is expensive for large projects but not so bad for this size. You would need 2 sides at roughly 12"x3"x.5" and the center at 12"x3"x1.75". This can be cut from one block of wood if you want. We would cut your rough stock down to those dimensions in the class. I used a 2"x2.75"x 24" board to make my plane.
If we have enough interest I will look at my calendar for July and submit the classes.
