How to bend wood

[caption id="" align="alignright" width="51"] Lumber (Photo credit: Starbug)[/caption] Bending wood is not a difficult task, which seems to be at first glance. Depending on the degree of curvature, and whether or not a curve, and a couple of ways of bending wood. First, it is necessary to have a way to bend the wood around and attach the desired to keep in shape. Bentwood and most have some degree of "flexible", so you must build your model with expectations for this purpose. And, unfortunately, there is no specific formula to determine the degree of spring back occur because the types of wood. Spring back also influenced by the method of use of bows. That is, the steam coming out of the wood, Or "unbend" more than plywood and this is glued. Another variable is the type of adhesives used in the lamination. As a general rule, the tighter the turn, and more for the return of spring wood, making it to refer the matter of trial and error at best. As laminating thin slices is the easiest way, let's start with this process. The thickness of the final project has a direct impact on the size of strips to be used, but in general, high band to use approximately ¼ "thick. Curves must be closed with 1/8" or thin slices, depending of the types of wood. Seems like a lot of experimentation, but I am afraid that this is a necessary evil. Can be in the form required for laminating be as simple as a piece of pipe or as complex as a set of multiple stations. I would like to keep things as simple as possible. When laminating thin slices, you can reduce the effort and return by soaking spring strips before bending mold clamping without gluing. Dry publish once, and remove mold, glue and reattachment of the mold. Align template with wax paper to prevent sticking to the mold lamination. By soaking sliced ​​done in an open container, and timber, depending on the size of the strips, I 15 minute soak overnight. I also mix half a cup of fabric softener per gallon of water. I think it reduces the wood almost as well as fabric. If the project is a small, open and waiting time is not a factor, and will use polyvinyl acetate, or aliphatic resin glue. If you need more time to work, will use epoxy or resorcinol. Kept Epoxides away adapt quickly, however, because they are rarely hardened to the point that slow groups do. If you are using a light-colored wood, resorcinol dries to a reddish color which may be rejected in the final draft. When was soaked Bretton thin bending, such as the sides of the wood usually guitar as above, but the curve template hot. Bending and electric, or heated with a propane torch and timber supports crisp on the outside of the curve with the Gaza stainless steel thin to help prevent cracking. Can green forest bend in the same way, or by heating the hot charcoal or wood on a good heat gun. Where lamination for unwanted projects, or when they are bent on wood in the compound curves, and steam box is the answer. One can be relatively inexpensive PVC pipe, but it is necessary to get support to keep the warp pipes. You must close the tube ends with screw cap at one end, to allow access to the interior. Put the other end of the tube with DWV reducing tee, and attach radiator hose along with a new port for gas and can be large enough to hold enough water to continue through the work. The water can be heated with a hot plate or burner propane. Drill through the pipe a little less at the center of two or three places wooden nails and insert in comfort. Steam must move freely through the woods to the break. Must dig a hole of about ½ "in diameter in the lid farthest from the entrance to allow steam circulation. When you create a support framework for the steam box, box for the release of steam to allow condensation to return to the water source. The rule of thumb says it should be steamed wood fifteen minutes per inch of thickness, but again, a little experimentation will be necessary. Timber must be placed in the way as soon as possible, because the timber is cooled, it is more difficult to bend. Make sure your timber at least two feet longer than the final part, because it is almost impossible to bend the 3/4 "piece of wood, which is less than a foot long, so the latter will walk to be cut after dry wood. Wood held safely, and leave it there to cool completely. If you are working with several pieces, and put it in a steam box about the desired interval to put a piece in the form of safe, out of the box in the same order.
