In this intractable you will learn how to create a bending form for bent lamination. These sheets come in 4 x 8. So the first order of business is to build the form followed by cutting the wood into lamination strips.
Drafting design fade out vellum. Try bending two thin strips together and see how their surfaces slide one along the other. It s messy but rewarding to see a gracefully bent piece of wood emerge from a glue encrusted form. There are many ways to construct a form and apply pressure.
