i am making a similar bend using the same would and the same angle and radius but i have been trying to soak the wood and then individually bend each peace round but it just keeps snapping. how did you get it to bend without snapping or soaking? is it because you are bending them all at once?
skillful and effective, but tricky: it wouldn't work with more complex shapes.
plywood should be bent from single plys, in order to allow higher bending and a correct edge grain section. your edge grain is weird: doubled in one way, single in the other one. (ok you could cut in alternate directions...) i
instead of clamps there should be negative and positive dies, so to properly distribute the stresses.
but when you do clamp the layers together i would add another piece of plywood without glue. so you can be sure that your clamps do not press in your workpiece!
I have a question though, Why did you cut the plywood strips allways from the same side? As the finished piece shows, you get 2 layers with grain one way and 1 layer with crossgrain, was that intentional?
I would assume that the plywood will only bend to that sort of radius when the face grain is going across the leg rather than along it. 1/8" ply would probably break if you tried to bend it to that radius the other way.
I'm a designer currently working on a project to design some sort of product out of moulded wood. Can't wait to get sketching to see what i can come up with using this process, then i can start making what iv designed using this exciting method. Wish me luck!
@bradfordashoemaker: The plywood I used is 1/8" baltic birch, and has 3 plys. Of course, you could glue up individual plys, but starting with 3 is less work. The drawback is that the minimum bend radius is larger than with individual plys.
@franciscoferrario: The glue between the layers resists lateral slippage, so it's probably not necessary to "overbend" the mold, at least not by very much.
there is no gurantee that your piece is square, you biased all the clamps pressue one one side, if you alnerate which side the clamps are on, you will get more universal pressure.
@franciscoferrario I didn't build it. but it's exactly 90. plywood glued like that wont be anywhere near as sensitive a a solid steam bent piece. plus if it did bend you could just sand the bottom of the feet flat. :)
great video and thanks for posting .

Love it, all that furniture is great, it's 60's and 00's at the same time.

thumbs up from a german carpenter!

keep up the good work !

is this plywood you are using 1/4" or 1/8" thick?
bradfordashoemaker 1 year ago
@bradfordashoemaker looks like 1/4

Use a cheap 1" paint brush to put the glue on with. It will spread pretty evenly.

Perfect explanation. It has helped me a lot.
But I have a question, the mold of the leg, is at exactly 90 degrees, or a little more?
Because I understand that the wood tends to its original shape.
