Webbending to a tight radius (e.g., less than 4"), it is best to use plywood for most of the form and insert a hardwood nose. If bending on a bench, screw the form down to a larger piece of particleboard and in turn secure that to your work surface. If you are using a bending table, you will have to drill holes in the form to match table holes.
