youtube-build-a-steam-box-yamaha Really good fun to watch … How to build steam boiler? Well nothing left but to test it and see how it works. The inner tube absorbs sunlight and boils water. Reply 10 years ago on Introduction. Sleeping on this concept last night I thought I might be producing to much steam.

Steamed wood compresses considerably but stretches little. For tight bends less than 4" radius , a steel tension strap with attached end blocks applied to the outside of the bend minimizes stretching [ Drawing below ]. Mild bends, with minimal stretching along the outside, do not need strapping. Parts incorporating convex and concave curves in the same plane require a two-part form to sandwich the workpiece [ Drawing below ] or special tension-strap hardware [ Sources ].

Tension-strap hardware also is available to form parts with bends in two planes. For best results, use air-dried lumber, with dehumidification-dried lumber a second choice.

The heat of kiln drying makes lignin less susceptible to softening by steaming. Use kiln-dried lumber only for gentle bends. All temperate-zone hardwoods chart below steam-bend well and, in general, bend better than softwoods. Steam-bending other temperate-zone species is possible, but limit their use to gentle bends.

Among tropical hardwoods, mahogany gives acceptable results. The brittleness of highly resinous tropical exotics make them unsuitable for bending. Regardless of the species you use, careful board selection increases chances of successful bends. Choose straight-grained lumber without knots or other defects and avoid decay even slight spalting. The greater the run-off angle, the more likely the piece will break when bent. Splitting wood from a larger straight-grained billet guarantees straight, parallel grain but is not always practical.

Straight stock runs through a planer or jointer easier than bent pieces, so do as much sawing, surfacing, or shaping as possible before bending. Surface irregularities can cause splintering, so remove rough saw marks. Holes or mortises distort or they cause the part to collapse or split; perform these operations after bending. Leave extra length at both ends for trimming. Where a bend is near the end of the part, extra length also provides the leverage needed to anchor the bend.

Cut stock for parts requiring tight bends so the annual rings lay flatwise against the surface of the bending form [ Drawing delow ]. For mild bends, grain orientation is less important. Steaming takes about one hour per inch of workpiece thickness and parts must stay on the bending form for one hour, so unless you make more than one form, the steam box only has to accommodate one part at a time. For efficient use of the steam boiler [ Sources ], a steam box should be only large enough to hold the part blanks with room all around for good circulation.

For tight bends on thick parts, increase box size to accommodate resteaming a partially bent piece. The steam box shown in [ Drawing below ] holds two leg blanks for the desk shown above and accommodates resteaming of a partially bent leg. Make bending forms from particleboard or plywood laminated to a thickness equal to the width of the bending blank. Bending a workpiece puts considerable stress on the form, so when in doubt, more form width beats less every time.

A two quart size is good for starters. You can fill it two thirds full and generate steam for several hours.

You will need a heat source. If you plan on working outdoors, a camping stove works fine. If you work indoors, you can use a hotplate. The hotplate I use runs watts. That is hot enough for the three foot steambox I use and just hot enough for the 8 foot steam box.

Since first writing this Instructable, I have gotten my hands on a wallpaper steamer. It works much better than boiling water on a hotplate, mostly because it runs at a higher wattage and puts out more heat.

If you can get a used one, go for it. Cut the plywood to the dimensions that you need. The interior of the steam box should be large enough so that when you load it up with wood there will still be an inch of space around the wood so that the steam can get to the wood. Nail or screw the 4 sides together.

Close off one end of the box. Leave the other end open. Screw a piece of plywood that is 4 inches wider than the diameter of your cooking pot to the capped off end of the steam box.

Cut a hole in the center of the piece of plywood so steam can get from the cooking pot into the steam box.

Drill some holes in the side of the box to run your wire supports through. Keep the holes the same diameter as the wire to minimize the amount of steam that escapes or the need to do a lot of caulking.

The wires will elevate the wood in the box so the steam can get to all sides of it. Cut wires 4 inches longer than the diameter of the box. Run the wire through the holes and bend over the ends so the wires don't fall out.

Finding the hole at the far side by feel is tricky. Shine How To Build A Steam Box For Wood Design a light in the open end of the box and look through the hole that you are aiming the wire for. When the light disappears, you have found the hole. Set your pot up on the heater that you will be using. Screw some legs to the sides of the open end of the box so that it is level with the top of the pot. The level steam box is important so that the lid of the steam box makes a good seal with the top of the cooking pot.

If you're not that ambitious, you can just pile stuff under the open end of the steambox to raise it to the right elevation. When you're all set, fill your pot two thirds full of Build A Mini Steam Box Youtube water, turn on the heater and wait for the water to boil. After the water has come to a boil, the steam box still takes a little while to heat up.

Once you get a good flow of steam coming out of the end of the box, you're ready to heat and bend. One quarter inch thick ribs heat up in under 5 minutes. Thicker stock takes longer. Heat has to travel from the surface of the wood to the interior. Keep in mind that some woods bend better than others.

White oak, red oak, ash and poplar all bend well. Straight grain is important as well. If you have rain running out of the face of the board, your wood will most likely break where the grain runs out. It's really easy to leave on the heat when you're done bending wood. Eventually, the Youtube Build A Steam Box 80 water all evaporates, the pot becomes hot and the plywood starts smoking. Good way to start a fire.

The placement of the wire could be made easier by drilling of the holes and placing the wire As you assemble the steambox rather than after screwing the box together.

Soak the wood you want to bend in water for at least a day before steaming. This will make the wood much easier to bend after steaming. Place the lumber you want to bend in a container full of water, completely submerged, Youtube Build A Steam Box Location and soak it overnight before you steam it.

Keep in mind that air-dried lumber is easier to steam than kiln-dried lumber. Woods with more open grain, for example oak, are the most easy to steam bend. Place the moist wood into a steam box.

A steam box may be constructed from wood or PVC pipe. The steam box needs to be big enough to let the steam flow around the piece of wood and needs openings, like drilled holes, so that the steam gets airflow and does not become volatile.

A steam box is essentially just an enclosure that opens at 1 end and has a hose running into it from a steam generator. If possible, work outside when you are steam bending wood. Steam gets very hot, so be incredibly careful around the steam box and generator. Wear heat-resistant gloves and safety goggles while you are steaming and bending the wood. Hook up a steam generator to the steam box with a hose.

A steam generator may be store bought or you can use an appliance like a wallpaper steamer. Attach the steam generator to the steam box via a hose or tube.

They are available cheaply at most home decorating stores. If you made a homemade steam box, you can drill a hole to fit the hose or tube that connects to the steam generator. Steam the wood for 1 hour for every 1 in 2.

The general rule for steam bending wood is 1 hour for every 1 in 2. This is the temperature that water boils at, so as long as you have proper ventilation in your steam box the temperature should stay close to this number.

Open the steam box door to reduce pressure and temperature if it gets more than 2 degrees higher than this. You can add more ventilation to your steam box by drilling holes if you have difficulty maintaining the temperature. Remove the steamed wood with heat-resistant gloves when the time is up. Turn off the steam generator and carefully open the steam box with heat-resistant gloves.

Remove the steamed piece of wood and begin the bending process as fast as possible before it loses its pliability. Method 2 of Insert the piece of wood you want to steam completely inside a plastic bag. Use a plastic bag or plastic sheet tubing that is big enough to cover the whole piece of wood from end to end. If the bag only has 1 open end, then cut a hole in the other end so the steam can escape from both sides.

Clamp the bag with the wood to the side of something or set it on saw horses. Use clamps to secure the wood to the side of a workbench or other support.

The idea is to suspend it in the air to allow the steam to flow around the wood in the bag as much as possible. Try to steam wood outside whenever possible.
