You may know how to cut and sand plywood, but bending it is a totally different skill set you need to master, but this woodworking how-to will show you the right moves in seven easy steps. In the video, a bend is being applied to plywood for a curved chair leg, but this method could be used for any kind of plywood bends.
Firstly, you'll already need a wooden bending form, which is not shown. To start, you'll need to cut the strips of plywood with a bandsaw. Once you've done that, you'll need to clamp the plywood down to the wooden bending form for a dry run to make it flexible. Then, take the plywood off and glue the strips together and clamp them back on the form. Once fully dried, unclamp again and lightly sand the edges to remove the excess glue. Then trim the edges to the desired width on the bandsaw and sand again.
