Bent Wood Lamination Glue

I ve got a lot of questions on laminating wood techniques and i notice a number of folks are interested in how to laminate plywood sheets.

Bent wood lamination glue.

If you are using yellow glue this does not leave a lot of time. Use plastic resin glue or epoxy. There are many ways to construct a form and apply pressure. It also covers veneer laminating.

Yellow glue sets soft and fast. It is also prone to glue creep a phenomenon in which the cured glue creeps out of the laminations over time resulting in unsightly raised glue lines. So the first order of business is to build the form followed by cutting the wood into lamination strips. The laminate parts need glue between each layer and to be clamped to the form before the glue dries.

When it comes to wood laminating pieces of plastics or another layer of wood are laminated to composites wood or plywood. A couple of glues that seem to be good choices for bent lamination are. Then put against the original form. Pro glue unibond 800 i realize th.

In doing research before attempting my first bent lamination i m starting to look at the appropriate glue choice for the project. There isn t one adhesive ideal for every application. Adding a maximum of 8 powdered cornstarch by volume makes the glue more rigid and controls springback. Part 1 of a bent lamination glue up.

Once the glue dries the workpiece will hold it s new shape. The glue lines from jumping out. Unfortunately it is not particularly rigid and does not have much open time. Because bent laminations are under constant stress they require glue that sets hard.

Quite a while back i did a series of glue tests on bent laminations. With domestic wood laminations the simplest and least visible glue is pva polyvinyl acetate yellow glue. Don t use yellow glue titebond for bent lamination. With glue between each lamination a press is used to bend the bundle of laminations around a form.

10 layers 1 8 at about 5 radius after the glue had cured for 24 hours on the form the parts were laid aside for at least a week. All the real time pitfalls and stressfulness. What you need to use for bent wood lamination is 1 8 bending poplar plywood that comes in either long or short grain. Of these four glues urea resin and resorcinol achieve the most rigid glue line when cured.

Epoxy urea resin resorcinol and polyurethane are all good choices for bent laminations. The wood used was hard maple one of the more difficult from both the glue adhesion and bending stiffness. While resorcinol has a.
