A good collection of small clamps is essential to a well-equipped workshop. Your 48-in.-long clamps may sit on the shelf collecting dust, but your small clamps will never have the chance. Tom Begnal uses a variety of small clamps to cover the common small woodworking tasks, but he wanted to explore the many types he hadn't used. So he gathered about 40 different models in the shop, and set about using each one in a variety of common woodworking applications. The clamps he found the most useful fall into five general categories: spring clamps, bar clamps, cam clamps, one-handed bar clamps, C-clamps, and hand screws. He tested several sizes and models in each category.
