Steaming is an effective method of softening or plasticizing wood known as steam bending wood so that it may be molded for craftsman and industrial applications, such as the manufacture of furniture and boat parts.

Homemade steam generator for bending wood approach this method differently, depending on the type of wood grain and the quantity of the material involved in the project.

The timed process involves placing wood scraps in a box, which is supplied with heat via a steam generator. Once the wood pieces are steamed, they are pliable and immediately ready to be shaped during the second part of the steam bending process, with the aid of a jig and other shaping equipment. Generally, homemade steam generator for bending wood should be moist before initiating the steaming process, as damp wood is most effective with heat transfer.

Some woods already have high moisture content while others will need to be pre-soaked. As a general rule, hardwoods are well-suited for steaming homemade steam generator for bending wood bending than softwoods. Experts note that cross-grained wood is more susceptible to cracks and overall bending failure than straight-grained wood, which should be noted before processing the wood.

Greenwood, which has a moist composition, is the standard recommendation for steaming and bending, though different applications require hardwood selection. What is the best wood for bending? Bending qualities of various hardwoods were tested by the U. Forest Service and the results show that white oak, hackberry and red oak were ranked as the best woods for steam bending, while soft maple, yellow-poplar and hard maple were ranked as the least compatible with the steam bending process.

The integral tools used for the steaming process include: a steam boxa steam or heat generatora thermometer and a hose or other device that will connect the generator to the box. Steam boxes may be constructed from wood or from PVC pipe and must completely encase the wood scraps so that the steam may saturate the entire length of the lumber. Some professionals prefer to construct racks within the box for the individual pieces of wood to rest on, though this is not mandatory.

While the box should be tight enough to hold steam, it should also include an opening, like a drilled hole, so that the steam may flow around the wood. Openings are also crucial so that the steam does not become volatile. Additionally, many steam boxes feature a door so that pieces may be added and removed when necessary.

The general time guideline for steaming wood—advised by professionals— is one hour of steaming for every inch of wood that is processed. According to the Department of Agriculturedegrees Fahrenheit is the sufficient temperature to saturate the wood, and this can be monitored by placing a thermometer at the opening of the box. If the wood has been steamed for the allotted amount of time and cracks when it is bent, then it has been under steamed.

To avoid this, professionals recommend inserting a few test pieces in the steam box. As a general rule, the steamed wood should be placed on the bending clamp immediately after it is removed from the steam box to prevent fractures.

Bending forces the flexible outside fibers of the wood to stretch while it compresses the inside surface. The wood is then clamped secured by straps to the form which it will be molded to.

Mar 25,  · I'm wondering it anyone has any experience building their own steam box for wood bending and what they have used (electric) for generating the steam. I know you can buy generators for the specific purpose, e.g. the Earlex Steam Generator, but has anyone had any success using a fabric steamer or steam wallpaper remover to generate the steam? But Earlex now sells a steam generator that is easily hooked up to a steambox. It is safer and shuts itself down if it runs out of water (look for a review in a future issue of the magazine). When you are getting started with steam-bending, it’s best to try something easy – like the crest rail of a chair.
