It s messy but rewarding to see a gracefully bent piece of wood emerge from a glue encrusted form.
Bent lamination form.
A bent lamination is simply a board sliced into thin flexible plies and glued back together in a form to create the desired shape see photo above.
There are many ways to construct a form and apply pressure.
What you need to use for bent wood lamination is 1 8 bending poplar plywood that comes in either long or short grain.
Learn how to make wood magically bend to your will.
Bent lamination form how to.
If your radii is tight you can use 1 16 wisa italian bending plywood.
Nearly any saw can be used for kerfing.
Last updated on tue 11 aug 2020 bent lamination bent lamination is a process of bending thin strips of wood using lots of glue and lots of clamps.
There is a correction to the lamination formula given in the video.
Essentially by kerfing the part you are making it thinner so it can be flexed to follow a curve.
Using clamps or a vacuum press and we will look at both methods.
So the first order of business is to build the form followed by cutting the wood into lamination strips.
The process starts with ripping some thin strips of wood and applying glue to each strip.
I made it at techshop http www techshop ws what you will need.
Actually there s no magic required.
Drafting design fade out vellum.
There are two basic ways to clamp the parts while the glue dries.
Bent lamination is based on the principle that if several strips are glued together face to face against a rigid form they retain the shape of the form.
The formula is y amount of springback x depth of chord desired to bend n number of layers.
Kerf bending is the process of cutting a number of slots into a piece of material that allow it to bend.
While this method is not very strong it does allow for easy forming of wide or tall parts.
Lamination is the process of bending many thin parts together and holding them in the desired shape until the glue between them dries.
Try bending two thin strips together and see how their surfaces slide one along the other.
Once dry the resulting part will pretty much hold its shape forever.
Bent laminations don t take a lot of specialized equipment.
The more seams you have the less chance for springback.
With glue between each lamination a press is used to bend the bundle of laminations around a form.
These sheets come in 4 x 8.
In this intractable you will learn how to create a bending form for bent lamination.
