Today in the Shop "Building a steam box"
Got a later start then I hoped for and didn't finish it today. The good news is that I almost finished. I should be able to drill the holes for the dowel and install them and then add steam to see how bad it leaks. If it too bad then I might have to tape the joints with duct tape or something.....
So I took a few pictures to share. I decided to use my tried and true setup, I have really enjoyed using my two centipede tables, this one for smaller project and the large one for full sheets of plywood projects.
I found it is much nicer to have a plywood base to work on for almost all the projects. I have this left over sheet of plywood from my last storage rack build that is a really good size for it.
When I want to cut on it I add this sheet of pink foam that is also sized to fit pretty well. I use the plywood good side down so the rubber feet hold good and then the ruff side of the plywood is up against the foam so it holds well.
I went with the cheapest pine I could find. As you can see the length of 4 feet can vary a lot. The other ends are lined up and this is what the results are:
Now there are many ways to get them all the same length but since I have a festool saw and rail I love doing it that way. I start at the "even" end and cut the boards all together and get them both even and square. I took off just a little bit to preserve the most length I could.
Then I went to the other ragged end and again make a cut to even them and to get them square.
BTW in case you missed it I had clamped the boards together so they stay together like a single board. A single clamp in the middle worked for that.
Then it was time to figure out where the screws were going to go and mark the locations. Since I was on to assemble I pulled the foam off to preserve it for a bit longer. I also didn't want to drill into my plywood so I put some scraps under the work pieces.
After pre-drilling I started to assemble the box connecting two boards together twice. This picture shows that:
Then I took the two sub assemblies and made the box:
At this point we going to take a short intermission while a get a snack. I'll be back and we can see how it goes together.

Re: Today in the Shop "Building a steam box"
With the box together it was time to add some legs. The plans call for the front or door side to be higher then the steam feed side. In my scrap bin I found a couple of pieces that seem to fit the bill. I clamped then together and then used large bit to drill a hole.
So when the clamp comes off you have two parts that look like this:
I then drilled the legs so I could use a reasonable length of screw to attach it to the box. Countersinking large enough so I could use my drill with extension to screw them on.
The longer leg was done the same way but of course the hole was deeper.
This is what it looks like with the feet on:
Now it needs the back cover, the one where the steam enters, it has a hole for the steam fitting in the middle. Now I made no attempt to get the box square and the lumber was doing its own thing. If I had to cut the end and get it to fit then using tools designed to make things square don't work so well. However the way I did it works fine, first tracing the end on a piece of wider pin first. Here is what it looked like, X marks the center for later drilling.
Again using the festool track to align to the line made quick work of the non square cuts.
I did the other end the same way and that work very well.
And that is it for this post. I'll be back shortly to continue the story.

Now we are at the stage where we open the steam bending kit box. Exciting for me be much less so you you I'm sure, well unless you go and order one for yourself and get to do your own box opening.
I then got the steam fitting out and drilled the hole for it. There is a nut on the inside and then this threaded portion for the hose. Here it is mounted:
Next it was time to mount the hinges. And here is what they look like:
Then the latch they supplied:
They don't supply a gasket for the door so you have to. What I had hoped to use I have lost somewhere in the shop......... so I went with what I could find. Time will tell if it will work. Anyway it is in place and the open door with gasket looks like this:
And that is as far as I got this afternoon.
I'll add the final details after they happen and then we can get on to a live steam test..........

Re: Today in the Shop "Building a steam box"
Very nice work, Ed. What kind of projects do you have in mind for steam bending?
Re: Today in the Shop "Building a steam box"
I like how you did the feet! Never would have thought of that myself.

Re: Today in the Shop "Building a steam box"
I am getting excited to see the results ! I have seen them made of PVC pipe but never out of wood. Very anxious to see how the Rockler steam generator works.

Re: Today in the Shop "Building a steam box"
As of 2:40 this afternoon steam is on!
So what has happened between times? Well that is what this post is about.
The "plans" give few details so I'm winging it mostly with hopes I'm close enough for it to work well enough.
My next task was to install dowels for the work pieces to rest on in the steam room. I had some 5/16" dowel material so I went with that. I was also very unsure as to where the dowels should go, how many of them and all the details between.
My approach was to do just 3 dowels to start with and then go from there as the need or facts come in to play. Since I want to have some flex ability early on I went with a piece of plywood and drilled three holes in it, this would serve two purposes, first it will allow me to use it as a guide for where the holes in the box would go and second I can pull them out and plug the holes if I'm wrong about placement or size.
So with the three holes it looks like this:
The holes are 5/16" and using the same brad point drill I use to drill them I can mark the hole locations on the box. Of course I had a guide line on the box to start with.
With the hole locations marked I went to a drill guide to make sure the holes were vertical. This is my standby tool for this:
With the holes drilled I then inserted the dowels until they touch the far side (hole only on one side). Using the plywood I marked the lengths.
I cut the dowels and put them into the box.
Now comes the time to see how well I did. Will the plywood fit? Of course it does.
So now let's take a look inside:
At this point I have to get back to the steam box and see how it is doing, actually I've slipped away a few time to check on it but now I have to do a few prep things for the project that is in the box.

Re: Today in the Shop "Building a steam box"
Next I need to drill a "small" vent hole in the front cover.
The rear cover needs a drain hole.
At this point the box construction is finished enough for testing.
The steam generator label might be of some use to those thinking about by passing the kit for a more diy version.
Next it was time to connect the hose. They screw on both ends.
We have hard water so I got a gallon of this for the steam:
After filling the tank I plugged it in and let it start cooking.
I did not have a meat thermometer so that hole is missing as well as the function. Sometime this week I'll go shopping for one.
OK then I'll be back later with some more information and details of what happened.

Re: Today in the Shop "Building a steam box"
Looks like no joy in Aurora today. Three strikes and I'm out.
In each of the cases twisting to 90 degrees was no problem. Somewhere near 180 degrees things went bad. You hear a crack and then it just splits open. Only one the three got any where near the 180, in fact it just about make it but not quite.
So this leaves me with two options. One is to scrap the whole idea of the twisted wood or to try a few new things. This was a project that I needed to get done by next weekend so I don't see that happening. Perhaps on to other things then get back to this later in the fall.
Thinner wood, different type of wood and seeing if I can live with just a 90 degree twist.... Well perhaps I'll just have better luck next time.
I read 136 degrees on the outside top of the box. Wish I had taken a reading inside the box when I opened it but I wanted to get a work piece and get it closed back up so things didn't cool down too much. Next time perhaps.
The aftermath:
And the worst case:

Try steaming it longer ?
