We refine wood into different products such as plywoods, chipboard, timber, wooden construction components, interior panels and pre-fabricated houses.

Select the kerfing method when the inside of the bend will not be visible and when the bent plywood will not be subjected to substantial force.
Kerfing weakens the plywood and should only be used where the bent surface of the plywood will not be supporting weight. Consider laminating and bending several thin pieces of plywood when strength of the final piece is a primary consideration. Like steaming, laminating several thin pieces of plywood together requires the construction of a form.
Turn on the heat source for the steam box and steam the plywood for approximately 1 hour per inch (24 mm) of plywood thickness. Put on heavy gloves, then remove the plywood from the steam box and immediately bend it over your form.
Stack you pieces without gluing them and clamp them to the form, attaching the first clamp in the middle of the plywood stack. Stack the plywood pieces and clamp them to the form in the same manner used during the conditioning step. Learning to bend plywood is an important first step if you are planning to create a product that will have curved, rounded or contoured surfaces. For instance, kerfing is not an appropriate method for bending plywood to make a skateboard ramp.
A knot, especially on the finished (uncut) side, will likely result in failure when the plywood is bent. You can fill them with wood glue before bending the plywood if the kerfs will not be accessible once the plywood is bent and secured into position. Press your steamed or laminated plywood over one piece of the form and then clamp the second piece of the form over the plywood.
