He outlines its shortcomings, too, and tells you how to decide whether to steam-bend or laminate.

Full-text available.  Jig (Pegged Form) and Steam Chamber A 19mm thick plywood board and wooden dowels were used to prepare the jig for the steam bending tests (Figure 2). Holes were drilled along curvatures of mm drawn on the board, and dowels of 12 mm x 12 mm x 50mm were inserted into the holes. View in full-text.  The aim of this study was to investigate the mechanical properties of oak (Quercus petraea Liebl.) wood bent at different radii for locations of the tension and compression sides of wood using micro-mechanical test specimens. Two oak trees having straight stems with approximately 40 cm diameter were selected and two 4 m long logs were cut.

Oak is one of the best woods to bend using steam because it becomes plasticised when heated and exposed to steam. Both red and white oak are ideal species to bend.

You could bend perhaps 1/8” dowel on a hot pipe but you’ll get breakage at less than a 90 degree bend a lot of the time. 1/4” rod could be coaxed into a mild curve. The problem with dowel rod is there is going to be so much grain runout the rod will break easily. You can improve your chances by splitting square. May 14,  · Oak is fairly easy to steam bend, but grain runout will produce a weaker finished product as well giving rise to potential failure during bending. As for the PVC steam box, make a 'V' trough to hold the plastic pipe its full length. Plastic becomes. well, plastic when it gets hot and will sag considerably if not well supported. Jun 07,  · I've read up on steam bending. But oak seems soooo hard and dense. The bend will be a half-circle about " inside diameter.
