Bending Hardwood With Steam -- Or Not
If a tree falls in a forest and no one hears it, does it make a sound? I ask because this was a project that took a fair amount of time, and I'm the only member of my family who will even notice it, probably -- and I didn't feel all that strongly about the need for it in the first place.
But it involved the attempt to learn a new skill -- which I kind of failed at -- so I'm going to document it.
I got a sailboat for my kids to use during the pandemic. It gives us a chance to get out in the open air without having to worry about contact with others. The boat we got is 52 years old, and it was pretty much the first boat we could find. It wasn't very expensive, and hasn't cost us much to bring up to speed.
Most sailboats are nice-looking pieces of design. They kind of have to be. The Lido 14 that we got has a lot of curves in its design. I like the way it looks.
But one part of it kind of bugged me. There's a little shelf down under the mast where you can set the halyard lines and other stuff. It's perfectly fine at what it does, but it's (pretty much) the only straight line on the boat.
So, I thought about what it might look like if that piece of wood wasn't straight. What if it had a curve that kind of flowed into the curved line of the hull? I got a piece of flexible trim and tried different curves to see what I liked.
The idea was that I could learn how to bend hardwood by steaming it. I got a piece of 2"x1/2" wood and figured I could run steam from a little teapot into a piece of PVC pipe for an hour or so, and then clamp the lumber into the bend I want and let it set.
Here's where I got it wrong. I had a 2" ID pipe and 2" lumber -- but in my head I was thinking that the 2" dimension would be finished at 1-5/8", like a 2x4. Of course, I was wrong -- the wood wouldn't fit in the tube.
So all I needed was a bigger tube. But that would mean additional time, and some expense, and this little project just didn't seen worth that kind of effort.
So I did what I considered the next best thing. I threw the piece of wood into the swimming pool for 24 hours, figuring I'd let it soak through, bend it, and then warm it up with a heat gun to approximate the effect of steam.
It didn't work very well. It was bendable, but the process revealed every irregularity in the one piece of wood I've gotten. There was a lot of kick-back as it dried, it twisted, it had one 'knot-adjacent' section that didn't bend on a smooth radius.
So I ended up tossing it back in the pool for a 4-day soak. The kids kept taking it out. When it was soggy, I made the clamped curve tighter than my final goal -- and positioned a bunch of additional clamps to force it into the final shape I was shooting for.
At this point, I gave the thing low odds of coming out in any useable shape.
But I was surprised. After two days of drying, clamped, in the sun, it came out with more-or-less the curve I'd originally imagined.
I stained it to match and transferred over the ©1960 manufacturer plate. The boat is actually a 1968.
So there we go. Will anyone notice the change the next time we're out sailing? No. Was it worth the time and effort? Well, it wasn't very much effort, honestly. I'll call it a completed job.
I still can't claim to have any real experience with steaming wood in order to curve it, but now that doesn't mean I haven't curved any hardwood.
The 'shelf' part behind it is 1/4"-thick plastic sheet.
Here it is:
