Rockler Steam Bending Kit w/FREE Bentwood Carryall Plan
The steamer worked precisely as advertised. I had to bend some cherry slats for a dining chair. I built a steambox with 4" PVC pipe instead of using the plans provided (personal choice, that's all). Followed the written directions and the steamer produced plenty of hot, wet steam. I doubled the steaming time as my 1/2 " slats had been kiln dried( which makes it very difficult to loosen the lignin bonds in the dry wood) and the wood bent, requiring considerable clamping pressure with screw-type f-clamps. I had previously built some bending jigs to receive the hot wood directly from the steamer. Not wanting to face any rebound-and-straightening pressure, I left the slat in the bending jigs for four days...The slats came out perfectly, holding their new form, with no return to their straight shape. I don't know why the black plastic hose had to be so long, but all in all I would highly recommend this product to others.

Great Steam Generator
I was impressed with the amount of steam this unit created. Plus, I liked all the fittings that came with the kit to assist in making the steam box. Speaking of which, I would suggest using a minimum of 1/2" thick exterior plywood rather than the 3/8" I used. I used a brad nailer to construct it and within a couple of steams, the box was beginning to come apart. By using thicker plywood, it would be easier to screw the sides together.

My daughter has been doing woodworking as her 4-H project for the past 5 years. She has accomplished Champion, Reserve Champion or Grand Champion each year at the county fair but only achieved Champion one year at the state level. Her hope is that adding steam bending to her skill set will help her achieve another Champion or even Grand Champion at the state level.

No where does it say that kiln dried wood does not bed well if at all. Air dried wood is what is needed. I asked at my local rockler and they can not tell me if their stock lumber is kiln dried or air dried. Where is a link of some sort to lumber yards that sell air dried lumber?
Mark B on Aug 14, 2016
BEST ANSWER: Kiln dried lumber bends fine you just have to steam it longer and bend slowly its actually a better finished product so i would say allow extra cost for time but exercise patience u cant rush perfection and dont forget compression to the ends if it stretchs in length wood will definitely seperate but to answer ur question kiln dried is fine to bend
What is thickest stock recommended for this unit?
Kent K on Nov 2, 2016
BEST ANSWER: They show using 3/4". I used 3/4" marine grade plywood so the heat and moisture doesn't ruin the box.
Do you have a 240 volt unit?
A shopper on Jun 18, 2015
BEST ANSWER: Sorry no, we do not carry a 220/240 volt version.
can you order a second brass fitting for the steam box?
Dave S on Dec 13, 2015
BEST ANSWER: I hope so. This product is virtually identical to a unit sold under the Earlex brand, so I would look at other retailers if Rockler cannot sell one. Also, this is a fairly standard fitting, so you could try an online pipe fittings company. I can envision at least a few reasons to have a second nipple, so I hope it is available for purchase without much trouble.
why does my box only go to 130degrees ?
A shopper on Apr 24, 2015
BEST ANSWER: The reason is simple physics. Google " temperature to boil water at 7400 feet" and the answer is 198F. The higher you are above sea level the less energy / heat is needed to boil water. On Mount Everest water boils at 160F.
The front door keeps warping How do I stop this?
Wayne R on Mar 31, 2017

Can you straighten wood that has a bend in it ?
lowery l on Sep 28, 2015
BEST ANSWER: Wood can be straightened but it depends on the size and shape of the steam box itself. For larger wood projects, this unit is too small and does not produce sufficient heat. There are lots of home made steamers that work great for large projects. I did 2x2x48 inch oak for replacing rockers using a turkey fryer and a cleaned out metal 5 gallon gas can as the cooker. Thermometer topped out at 180 degrees and I did not have to refill after steaming for 4 hours.
I'm a first-time wood bender, and have a large project in mind. I want to bend 2x4's into a hobbit-esque front for my chicken coop. I'm pretty sure I need more steam then what one of these guys produce for such a project and am needing some safety and hook-up recommendations to use more then one on a steam box. Any pointers?
Krista P on Mar 9, 2016
BEST ANSWER: You are right about this unit not being up to the task. I don't believe any non-commercial unit would do it.
I recommend using thinner stock and exterior glue to build up to 2' X 4' dimensions. You can build a jig
and clamp the stock (recommend 1/4" to 1/2" plywood or solid stock) or steam and clamp. Hope this helps.
The steam box plan recommends using solid wood or plywood. Can MDF be used to construct the steam box?
Jules J on Nov 13, 2015
BEST ANSWER: The steam is difficult for most wood-based products to handle. I have used exterior grade plywood, and this works great. You can tell if its the right stuff, as its glue between plys is dark brown. I do not think MDF would last, and would advise against it.
If I use 2 of the Rockler steam bending kits will I be able to bend a deck board (10'l x 6"w)?
Gordon P on Apr 29, 2015
BEST ANSWER: General rule is one hour per 1 inch thickness. Because because your workpiece is large, you'll lose alot of heat into the box and into the workpiece. Based on the required size of the steam box and workpiece size, you might want to use 2 generators and double the time (or regular a single generator 4 times with pre heated water)
Has anyone used large-diameter plastic pipe (with fitted end caps) instead of the wood steaming box?
Lafayette Sawdust Guy on Oct 9, 2016
BEST ANSWER: YES, this has been done, and has been published in Fine Woodworking, I believe. It is used for longer parts, or when the number of parts to be steamed is few in number. You still need to support the wood, to keep it off the walls of the system, so that the heat and moisture are in contact with all surfaces of the wood. The plastic pipe sags when heated, so support it every ~two feet with something shaped like a half circle. Remember the plastic will get very hot, too hot to touch, and you MUST vent the system. Steam under pressure will increase in temperature past the boiling temperature of water, and can severely burn you.
Can I use this generator with a plastic bag?
Michl on Dec 3, 2018
BEST ANSWER: I would not recommend it. The plastic bag would melt.
Outside bending wood for guitar sides which I am considering can this be used for extermination of a bed bug problem which requires steam. I like dual purpose and bedbugs I am going to deal with this. Will this work for treating bedding, furniture and wall corners. I know they make steamers for treating bedbugs and I also considered for bending wood. My question is will it work?
Michael on Jan 9, 2016
BEST ANSWER: I would worry about damaging your mattress and letting moisture in. You can also buy mattress covers that are hypoallergenic that will trap the bedbugs inside. This steam generator probably has the generation capacity you'd need but you might cause damage in the process.
What is the steam production rate in kg/h?
Slobodan P on Jun 27, 2015
BEST ANSWER: Roughly 3.3kg/hr assuming no leakage.
is there a thermometer with the kit?
me on Feb 26, 2018
BEST ANSWER: Andy, there is no thermometer. If the chamber is built well it should get to 200 Deg. in about 10 min.

I have some wood furniture that is glued together. Can I use this unit to apply steam to get the glue bond to release so I can disassemble and reuse the
materials used in the furniture? I tried a heat gun but it will take significant amount of time to soften bonds between 2x4s and plywood sheets.
JEK on Jun 11, 2017
BEST ANSWER: If you are disassembling a large piece of wood, it will not do it. You can pre soak it for two to three days. Insert something sharp at the end of the wood like a flat chisel to give it a head start then use the steamer according to the thickness of the wood. The thicker the wood the longer it takes
Can I use steamer to bend heavy timber 3" x 7" x 13'?
Tony A on Sep 15, 2019
BEST ANSWER: Tony, an old rule of thumb in steaming lumber is that you need to apply the steam continually for one hour per inch of wood. Also, generally speaking, you need to build a box big enough to hold every individual piece of wood you are steaming. That said, I don't know how you want the bend to be. If you want to to make an arc out of the piece, you probably will have to steam the entire 13 feet inside about a 14 foot box. I have never steamed wood that thick before, but depending upon whether you are bending the 3" side or the 7" side, I I would guess it would take up to a day of steaming then using a very large and heavy duty jig (picture an oversized metal bending jig) to make the bend....possibly even requiring a small 5-ton jack to make the bend. You might have to steam for about 10 hours then try and see if it will bend. Good luck....I would be interested to hear/see how you do. Jack
What is the wattage of this steamer and is it just powered by an AC outlet?
Brad B on Jan 19, 2016
BEST ANSWER: Yes, this steamer is powered by a normal, three-pronged household AC outlet (120V - 60Hz), and the wattage is 1500W. Once you build the steaming box, as per the plans that you can download, it's a very simple unit to use. A great addition to the shop for bending wood!
why can't I get my wood steaming to get above 135 degrees?
A shopper on Apr 24, 2015
BEST ANSWER: I have no problem getting 200deg.The box that I built is only 3'x3'x6" outside using 3/4" pine. I followed the plans. To give a few hints as to why he can,t get the temp.:... first,. is the heater putting out 200deg plus? 2nd is your box too large in length and/ or the volume too large (may need 2 heaters). Third, how airtight is the box that he built (too many leaks, and your steam is getting out). Fourth, is he doing this inside or outside .. where the ambient temperature could be a factor.I do my steaming inside the house in the basement. Another hint is to put some insulation around the box. Hope this helps.
how do I order a new power cord Cant find mine after a move and no other chord fits?
Karroll H on Apr 28, 2020
BEST ANSWER: Karrol, if you have an old computer monitor cord handy, try that first. From the specs it looks like a standard three prong cord. Did a quick search and found one on line for about $9. Try searching for these key words " Computer Monitor TV Replacement Power Cord - 10-Foot, Black".

can you bend pvc with this unit?
Cory on Apr 21, 2017
BEST ANSWER: PVC bends at 170-220. So, if your box gets that hot, you're good to go. Google PVC bending for more.
Good Luck.
Can schedule 80 PVC be used as a steam chamber?
vinnie on Nov 29, 2016
BEST ANSWER: That will work well. I use the PVC when my stock exceeds the size of my steambox.
How hot is the steam when it's released?
Elvis C on Jul 21, 2016
BEST ANSWER: At sea level, water boils (becomes steam) at 212F (100C). So this is the temperature when it leaves the steam creation chamber. I live at higher altitude, so when my steamer is running, my steam box, which is 12x12x60" gets up to~196F at hottest. DO NOT SEAL THE STEAM BOX, this will pressurize the steam. This does not help steam bending, and makes the temperature rise to higher temperatures. I use welder's gloves to protect myself when I open the steam box door for any reason. Hope this answers your question
Can you bend wood poles for canes?
James on Apr 18, 2020
BEST ANSWER: I have never tried. But I cannot imagine why it wouldn’t work. It depends on thickness and time in steamer. I would thick the fresher the pole the better. I plan on making several bent wood cedar gates from boughs cut this year in the near future and don’t expect any problems. Good luck and let me know ant tricks you learn along the way. J
I am needing to bend red oak in a 12" circle, the size of the wood is 3/4" x 1". Could the steamer handle this in one piece. ? Thanking you in advance. Ross.
Ross M on Oct 14, 2018
BEST ANSWER: I have my doubts that your oak would hold up after drying even if you could bend it to a circle of 23” that is extremely tight and would require a lot of steaming. I would rip your oak into thin strips of 1/8” each, steam them, bend them, dry them and then glue each back together into your circle. The only problem would be that you have to start with a thicker piece of wood to allow for the blade loss of your table saw. Good luck, Ken
Can someone give me an estimate on how much it costs to build the steam box? 3' long by the x 3" or 4 inches following the Rockler plans. I need an estimate to include in a grant application budget. The estimate does not need to include the steamer since that price is clear
Karlyn B on Sep 22, 2018
BEST ANSWER: I don't have an exact answer because another person from my chair making class made the box for us both to make more chairs. Our box is about 5 feet long and maybe 8x8 inches--The box is in a different town than where I live, so I cannot give exact dimensions. We used 2 of the Rockler steamers --our pieces to be bent were 1 and 3/4 inch by 1 and 3/4 inch and about 50 inches long--so we needed a box a lot bigger than your proposed box and more steam-hence the two steamers. You can use exterior plywood--one half inch to 3/4 inch thick--a one half sheet of it should be plenty for you. You also need some hardware--screw the box together, a hinge for the door and a latch for the door. Oh, I see now from Rockler ad that the kit includes hinges and latch. You should start with hot water, so you could get one of those pots that heat fast. But if your pieces are small, you won't need to steam a long time (we needed to steam 1-3 hours for our chair parts)--you should be able to just use one steamer. I would guesstimate $20 for hardware and a few 3/8 inch dowels (for the cross bars for the pieces you are steaming--you don't want to let the steamed pieces just lay on the floor of the box--you want steam to enter all sides of the pieces and $ for whatever a half sheet of exterior plywood costs. Best to set up the steamer outside. If you google steam boxes, you can get some great suggestions.
Sound more complicated than it is, so have at it, and good luck!

I would like to bend 8ft material whats the biggest steam box this can handle?
Anthony S on Sep 23, 2017
BEST ANSWER: This is a tricky answer. The steamer produced steam for a 1/2' X 1/2' X 4' (interior dimensions) or 1 square foot of space. Meaning that generally preserving this volume of 1 sq ft for and 8' length would mean a max of 1/4' X 1/2' X 8' or 1 square foot. The problem is as the steam tube gets longer it will take a longer time to come up to temperature and moisture at the ends. It would be wise to place a thermometer at the end of the tube to watch when the ends come to temperature then start the steam timer at that point. Make sure the steam input hose from the steam boiler is attached at the midpoint of the tube.
Could I make a crook with this?
Christian U on Apr 9, 2017
BEST ANSWER: Yes, have your form(s) set up & securely held down. Steam the wood for an hour per inch of thickness, then remove & apply to your form using firm pressure, but go slowly enough to allow the fibers to conform so there's no splitting. (Don't bend too fast-you can "feel" the wood give). Allow the material to remain on the form(s) a week or so, then slowly release the securing clamps. Hope this helps.
