Kerf lines are shallow, parallel cuts on plywood that allow it to flex and bend around curved stairs, furniture, cabinets or special. A quick method is to cut kerfs into the plywood, nearly full thickness, do a test to see how close together you will need to have the kerfs, bend the plywood to desired shape then fill all of the kerfs with thickened epoxy, this will make it keep its shape. Learn how to bend plywood. Hardwood plywood bends better than softwood. Place bar clamps across plywood thicker than 1/2 inch.
My question: Has anyone had experience bending panels this thick? Bending plywood is ideal for anywhere you need to create a curve. Timberflex is available in 4’x8 and 8’x4′ panel sizes and in 1/2, 5/8 and 3/4 thicknesses. But I don’t know how well it will bend. The plywood needs to curve around the fron bend, which is an 18-inch radius curve.
I always wanted to make a bent plywood chair so I went ahead and made this prototype. I used compression mold to curve the plywood and a water based resin glue to put the bendy ply together. Is it as simple as building a mold, steaming the plywood and tying it down? Any advice would be helpful. Kerfing allows for bending all sorts of thicknesses of stock, and is especially useful for bending plywood. Note here how I kerfed just the areas that were going to be curved, leaving the flat areas to be attached conventionally.
Bending Plywood Panels
Veneer Laminating: In the 1940s, several Canadian designers and manufacturers started producing revolutionary laminated and formed-plywood furniture using technology developed for aircraft production during World War II. The original plans call for a lower budget ACX plywood but I bought Hydrotek 1/4 and 3/8 to build from as well as poplar for the keel, stringers, etc.
