I am looking for a source that explains what is involved in bending wider pieces of wood. Like 6-8 inch wide boards like in these dressers

http://www.poshtots.com/baby-furniture/baby-furniture/dressers/sobey-dresser/18/4279/1323/21863/poshproductdetail.aspx

This is not what I want to do but it shows it can be done. I am wondering if it is done with steam or with thin boards laminated and bent?

I’m guessing those projects were done using vacuum lamination and bending plywood. The overall shapes would be done with a cross lamination of veneers and bending ply then edge banded with 1/8” thick solid wood. After flushing the banding, a final layer of decorative veneer would be vacuum pressed on both sides of the piece.

If the pieces are really high end, the edging would be cut from steam bent pieces of wood so the grain would be continuous.

You can get started reading about the techniques over at Joe Woodworker’s. There’s a lot more to learn but that’s a good start.

The people that invented that style of work used vacuum
veneering.

If you want to be easy on yourself, use 3/8” wiggle
wood, bend and fasten it to a plywood form you’ll
remove later, then use glue and air staples, glue another
layer of wiggle wood on top. The glue will dry and
fix the shape. Then remove the form from the bottom
piece. Then you’ll have a 3/4” piece. From there
you can build it up thicker, veneer it or fill it and
paint.

You could do it with steam bending but you’d need
to know about metal working to make the rigs to
do the bends.

The FWW reprint books on veneering and bending
cover a wide range of scenarios with curved parts.

Bending solid wood is a very do-able thing. However, only a simple curve is do-able for a first timer.

Compound bend is a very difficult for he who has limited resources and no training. Although I have bent a dozen or more projects with steam, I would never attempt the compound bend without a very good mentor and some more exotic tools than I posses.

You can easily veneer curves like this without a vacuum press.
Curved surfaces were being intricately veneered long before vacuum presses with hot hide glue and a veneer hammer. You can even hammer veneer after the piece is fully assembled.

As for steam bending this sort of profile, cupping would be a real problem. The easiest stock to bend is square in profile. The wider the piece gets for a given width, the greater the tendency will be for it to cup. I don’t have a lot of small bending experience with steam but I have a lot with bigger pieces.

Sam, how did you get the plywood to stay in that shape?

Pretty much the way Loren described above. Two peices of 1/4” bending ply, glued together on a form.

SO it has to be two pieces to hold its shap. Got it. It is like skinny bent laminations.

Have your say...
