Cold bending wood

Can you bend hardwood? To cold-bend wood , first resaw your stock into thin strips and plane it so the thickness is even. The thickness of the strips depends to a large extent on the radius of the curve. The tighter the radius, the thinner the strips.

It’s a wood that has been compressed in its length under heat and with moisture. When the wood cools , it can be bent cold. And I have yet to encounter wood failure with the stuff. It’s expensive compared to cutting down a tree, riving out the stock and bending it green. Therefore it can stretch on the outside of the curve during bending - no steam or backing strap needed.

Since the wood is first plasticized in an autoclave and then compressed in a hydraulic press, very tight radiuses can be bent. However, now we are heading to see how to bend wood with water chronologically. At the beginning of the process, we should select a particular type of wood what we actually want to bend.

Depends on the hardness or softness of. Steel shaped by cold bending can be found in applications ranging from commonly used everyday items to highly technical specialized industrial applications. Put the wood to be bent in the container and pour in the hot solution. Seal the open end of the container. It is important to keep the container warm.

Such bending is done without treating the wood. In bending thick pieces of solid wood , however, softening with steam or hot water or plasticizing with chemicals is essential. When a piece of wood is bent , it is stretche or in tension, along the outer (convex) side of the bend and compressed along the inner (concave) side. Understanding bending criteria is the key in determining which bending method is best for the application at hand. Great article for bending Australian timber.

Bending wood without steam can be a very successful method. Most people when you mention bending wood think of a steam box and steam. While this is an old and proven metho it is not the only method.

When microwaving, to generate steam, you must wrap the piece of wood in a wet paper towel and put it in your kitchen device. When bending wood around a form, the outside wants to stretch, the inside wants to compress and half way in between it wants to do neither (neutral zone). Bending thin pieces of wood can easily make them snap, crack and split. Just coat the wood with some white distilled vinegar and bend away without worrying about breakage. Bend wood easily using vinegar.

Steamed wood compresses considerably but stretches little. That’s why successful steam bending compresses the wood on the inside of the bend while restraining stretching along the outside.
