Editor’s note: Our Mind Upon Mind series is a nod to a 1937 Chips from the Chisel column (also featured in “Honest Labour: The Charles H. Hayward Years”), in which Hayward wrote, “The influence of mind upon mind is extraordinary.” The idea being there’s often room for improvement. To that end, we’ve asked you what else you have thought of, tried out and improved upon after building projects from our books.

This steambending tip is for kiln-dried hardwood.
I am building two staked side chairs from “The Anarchist’s Design Book” to go with our dining room table. Both are built out of kiln-dried cherry and I’m using the simple steambending jig as shown in the book.
The crests are 13/16″ thick and need to be steambent to a 15″ radius.

I have built four of these same chairs previously, two out of ash and two out of cherry. The ash crests all came out well, but I had several failures while bending the cherry crests. Even when using straight-grained wood, cherry is prone to cracking and is a more difficult species to bend than ash or oak. This time around, I had three failures out of my first four attempts. All the failures were on the outside of the curve.
I knew a jig with a compression strap would give better results, but didn’t want to spend the time and energy to build a more complicated, albeit better, jig.
I had seen articles or videos in the past about steaming wood inside a plastic sleeve. While thinking about the best way to do this, I remembered that we have a vacuum sealer machine in our kitchen.

The crest is 18″ long and 2-1/2″ wide before steaming, so an easy size to work with the vacuum sealer. Vacuum sealing makes the bag/wood combination smaller and easier to handle and clamp, but still leaves plenty of moisture.

Here’s my process:
1. Soak the cherry for several days.
2. Put the wet wood in the bag and vacuum seal.
3. Steam for one hour.
4. Put the wood and sleeve in the bending jig together and clamp expeditiously.
5. After the crest has completely cooled and is at room temperature (4 to 6 hours), I unclamp the crest, remove the sleeve and reclamp in the same jig. This helps start the drying process, but it won’t dry very much while in the jig.
6. The next day, I remove the crest and put it in a bar clamp to dry. The wood will still be very wet and there will be some spring back. Tighten the bar clamp to match the 15″ radius of the bending form.

The sleeve retains the moisture during the steaming process, which is more efficient in conducting heat. Steaming without the sleeve heats the wood but also removes much of the moisture. The bag also helps retain heat and slows the cooling process while transferring and clamping in the jig.
If you plan on doing much steambending, my advice is to build a jig with a compression strap. In lieu of a compression strap, I think this is a good workaround.

So far, this technique has worked well after a handful of attempts.
