I’m looking to make some 10 foot long battens to shape a project I’m working on. The battens will only be bent very slightly, I just want to be sure it bends into a nice arc. Which wood would be most suitable for this application?

Many woods will work. Look for straight grain pieces
and of course wood with knots won’t bend smoothly.

Clear softwoods bend well.

Straight grained woods can be bent without too much trouble and like Loren stated knot free would be the best. You can also cut thin strips and laminate them with wood glue in a form and allow to cure then once removed it should retain the bent shape. You can also make a home steam chamber and then bend the wood once it’s steamed but will still need to be held in place until the wood has cooled down and dried. Several sites on the net that cover what your trying to do. Also look on sites that deal with bow making.

Here’s a good site that shows laminate forming: http://www.woodworkingformeremortals.com/2012/09/make-quilt-rack.html

One thing I noticed making bent parts recently is the tendency of the laminated parts to spring off the original shape/form in about 25%.......I was using layers 1/8” thick (Mahogany), so I guess for better results , could be better to use 3/32” layers—like plywood does—OR making the radio/shape form25%. tighter.

If you are using the battens for say drawing a line any straight grain softwood will be fine.I have battens up to 20’ in pine spruce and cedar. They all have different bending characteristics. The dimensions will affect how stiff it is also. Use as stiff as will make the bend for the fairest curve.

I would also say that basically any clear wood (soft or hard) will work for gentle bends, even poplar, but for tighter bends, I would use ash or oak. Hickory, walnut, maple, birch, and others will also work well. I get beautiful clear ash in 10’ lengthst ath will take basically any bend when steamed and still easily bend in a circle over 10’ when dry if cut to 1/4-3/8” thick.

I find that Oak bends very well. Soak it in water overnight and bend it and give it a day or two to dry in the bending frame..

A note on soaking overnight in water. I used that technique on an apron for a round table. I used a piece of 4” pvc with an end cap, poked the lumber into it and tied it to my deck stairs so it couldn’t tip over. I filled it all the way to the top, used a clamp to keep the lumber underwater. Worked like a charm. the piece I got was from HD, so it was only 10 feet long.

Ash is very good for bending, has always worked well for me with steam..holds its shape well also.. Papa

pretty much any wood as long as its not cork, or balsa. Just depends on which method for bending you are using.

The woods mentioned above will do fine and whether or not you laminate strips together or use steam, boiling water or dry heat (heat gun) you will need to over compensate for the bend in whatever form you use. Good luck.

I’ve made several sailboat tillers from laminated mahagony and ash. With some practice and well thought out bending jigs, they work well.
