The oven tool is used for pushing & pulling the racks in a hot oven, a useful gift for the cook in the family. It's a simple project that teaches a lot of basic skills nor are any of the measurements critical, so it is quite forgiving & allows some imagination that needs to balance against practicality. It's an excellent project for groups. We made these in Indian Guides & my daughter made this with several of her shop classes. Only a drill, 1/2" drill bit, coping saw, & some sandpaper are needed once scrap wood of the proper size is obtained.
