Picture of PVC Steambox to Steam Wood
This instructable will go through a step by step process of making a Steambox to steam wood. Other steambox variations are made from wood, however this was the cheaper way to do it.

Step 1: Things You'll Need

Picture of Things You'll Need
-Section of 4" PVC pipe QTY: 1
(Mine came in a 10' section, 4" You can use bigger or smaller, this is what I chose)
-PVC 4" Cap QTY: 1
-PVC 4" Female Adapter QTY: 1
-PVC 4" Threaded Plug QTY:1
-5" Carriage Bolts QTY: 2
-Section Flexible PVC 1/2"
-PVC Primer
-PVC Cement
-Copper 1" to 1/2" fitting QTY: 1
-Moolah = Cash

-Mitre Saw
(I used a Sliding mitre saw because of the diameter of the pipe"
-1/2 and 15/64 Drill bits

Step 2: Cut section of PVC

Cut Section of PVC to desired length. I just added a half foot to the workpieces that I'll be steaming. My tube came out at about 54 inches.

Sorry No pictures of this one.

PVC makes a ton of mess when you cut it. Cut it outside, or over a trash can or something easy to clean up. Also, 4" is alot for a miter saw to handle, so you may have to cut halfway through, and rotate it, cut doesn't have to be perfect, but try you're best.

Step 3: Prep and add caps to tube

Picture of Prep and add caps to tube
Clean the tube as well as possible. I used a paper towel. Next apply primer to the tube, I would suggest applying it when the tube is on its side, or you'll make a huge mess like my old man did when he applied the first little bad, after that he wasn't allowed to touch anything.

Apply the primer to both the end, and to the cap, quickly apply cement to cap, Don't puddle it, but be gracious with the amount applied. Apply cap QUICKLY!!! and give it a 1/4 turn.

Next the other end. Apply primer to both Female adapter and the end of the tube. Apply cement, and install same way, remember the 1/4 turn as you insert the tube into the Female adapter.

Let it cure overnight, the package only says 2 hours, however I gave it a night to set.

You can lay the pipe on a flat surface, secure the pipe, then lay a marking device on a 2x cut to the correct height, then drag it down the sides. Both sides will have a mark the same height off the table.

Next, just measure from one end to mark the spacing for your holes.

Is it possible to steam wood with glued strips? I have a clipboard that I glued wrong and it's warped.

I used a shark steam cleaner as my source of steam.

Why steam wood? Is this used for bending pieces of wood permanently?
This is also good for people who collect surplus rifles. Steam works quite well for removing Cosmoline, a thick petroleum based preservative that is lathered on the surplus firearms before they are stored. It also helps raise various small dents or dings in the wood grains
I know your post is a few years old, but I just saw it. My wife get's angry at me, but when I am restoring a Garand, I stick the stock in the dishwasher on the hot water cycle. Strips it right off!

Yes, its used to make the wood plyable so that it can be shaped to a mold.

A PVC Rope saw would give you a cleaner cut here. They're about 2 dollars at the hardware store. Just chuck the PVC up in something, or make sure it is secured to something. Put the rope saw around the spot where you want to cut it and work it through the piece in a downward motion. A whole lot safer and cleaner than a saw. You also don't risk melting the end of the PVC from the cut.
Good post. Is wood merely soaked or is their actually steam in the box? How do you heat it? You could use a little Lacquer thinner and it will take of all the primer and the black writing written at factory.

I was thinking about doing something like this with a wall paper steamer, nice to know i was on the right track. I had to bend dowel rod for a sculpture project in school and had to use my bath tub, this would have made things much easier.
