Bending Plywood with a Form

Full Answer

How do you bend a curved plywood?

To bend plywood, start by creating a form out of medium density fiberboard that has the curve you want to bend the plywood to. Then, clamp the plywood to the form using bar clamps and leave it overnight. Next, unclamp the plywood from the form and try bending it to see if it holds its curve.

How do you cut plywood to size?

The entire sheet of plywood should be seated firmly on the work surface. A plunge cut is a cut that does not start from a straight edge, but the center of a sheet of plywood. If you need to make an opening in the middle of a sheet of plywood, for example, you would need to make a plunge cut. Set the blade depth.

How thick of plywood do I need to make a table top?

How do you make plywood more flexible?

If it needs to be cut to size before gluing you could clamp a long baton onto the ply and use that to give you the extra leverage. For a very tight radius it is probably best to laminate it up from several layers of thinner (more flexible) ply. The number of ‘plys’ will also affect the plywood’s flexibility.

How to bend plywood to make a shape?

Create a form out of MDF (medium density fiberboard). Use a pencil to draw the shape of the curve you want to bend the plywood to on a piece of MDF. Cut out the shape using a bandsaw. Trace the shape onto more MDF and cut out more layers for the form.

How to tighten a strap on plywood?

To tighten the strap with the ratchet, bring the handle of the ratchet up and down repeatedly. Each time you lift up the ratchet, it will pull in some of the slack. Continue lifting and lowering the handle on the ratchet until the plywood is bent to your desired curve.

How to remove ratchet strap from plywood?

To remove the strap, lift the handle on the ratchet and pull it all the way back so it’s flat on the strap. You should hear a clicking noise and the ratchet should stay open.

How to fix gaps in plywood form?

If you see gaps between the plywood and the curved side of the form, tighten a clamp over them.

Can plywood be cut to size to bend?

I think you will find that the plywood once cut to size will easily flex enough to bend ‘cold’ around your shape.

Can you steam bend plywood?

Steam bending is not something I would recommend for plywood. An alternative is to wrap the area which needs most bending in towels then pour on hot water. Or simply soak the ply overnight and encourage the bending by propping it on some batons then placing a weight on top.

What Are The Different Ways Of Bending Plywood?

In general, three ways are used to bend plywood, each with its advantages and challenges that need to be overcome. You will often find that people are not always willing to do the work required to bend plywood, as the work can far outweigh the reward.

What Tools Will You Need To Bend Your Plywood Without Damaging It?

Now that you know which techniques we will be focusing on, steaming the wood and layering it, we need to look at the required tools. You will need to use five tools in total when creating bent plywood; each one is rather basic but essential to the process.

How To Use Steam To Bend Plywood?

The layering technique is what we consider to be one of the easiest techniques when having to create a bent piece of plywood. However, you may want to use already existing pieces of plywood when creating your bent pieces, which requires you to use steam.

How thick should a plywood core be?

To maximize the solid-wood effect of lumber core plywood, it’s important to make the central core thick. If your goal is a 3⁄4“-thick panel (and that number is arbitrary – you can make whatever thickness you like), then your central core should not be less than 7⁄16“.

What glue to use for plywood?

This subject is open to some debate. The traditional choice is hide glue, and if you’re experienced with using hot hide in veneering applications, I don’t see a reason you can’t use it to make your own plywood. You don’t need any fancy tools, and we all know the holding capability of hot hide glue. My favorite, however, is Unibond 800. It cures hard and is very much like hot hide in its cured state. It is, however, chemical-based, and you may not feel comfortable using it. To each his own. Epoxy is also an option, but it is quite messy and will likely ruin your bag or press if you’re not careful about squeeze-out. The Unibond stays put and doesn’t squeeze out like epoxy. Yellow glue can also be used. I don’t recommend contact cement. It’s good for Formica, but not so useful for fine furniture.

How do I glue veneers to a bench?

To clamp these thin veneers, I slip a 1⁄2“-thick batten under the joint, then drive small nails right into my workbench (or a scrap of MDF if you’re sensitive about your benchtop) at the edges of the veneers. Apply glue to the joint, remove the batten, then press the joint flat to the benchtop. A piece of wax paper under the joint keeps the assembly from getting glued to the bench. Press the joint flat and feel that the glue line is flush. Now place a heavy weight on the panel and let it cure. That’s it. The nails keep enough pressure on the joint while the glue cures, and the heavy weight keeps it from popping up under the tension of the nails.

How to join veneers together?

To join the veneer, first tape the pieces together on the backside with blue painter’s tape, pulling the tape tight across the joint (the tape will stretch slightly before breaking) every 3″ or so. Now flip the veneers over and repeat the process with water-activated veneer tape, adding a single strip of tape down the joint.

How to remove blue tape from veneer?

Blue tape is a real bear to remove after coming out of the press. Once the veneer tape is on , flip the piece over and remove the blue tape. Make two pieces like this, one for each side of the core. These pieces should be just about the same size as the core, but never bigger.

What wood should I use for a central core?

I like to use mahogany, but any stable wood is acceptable. Mahogany has a fine texture, and it is stiff and light. These attributes make for a wonderfully lightweight but strong panel. Here’s the other important thing: This central core should be made from the most quartersawn wood you can find. Riftsawn is OK, but try your best to get those growth rings dead perpendicular to the faces. I usually have to select narrower boards to get the most quarter across the full width of the board, then glue these up until I get the width I need. This is typical edge-joining work. Easy stuff.

What is lumber core panel?

With a lumber-core panel, you can treat the entire panel as solid wood, attaching hardware in the same manner as you would with solid wood. A lumber-core panel, like any plywood, is made from an odd number of layers. This serves the purpose of balancing the layers.

How to cut a piece of plywood?

First, carefully set a piece of wood or plywood onto the working table saw, taking care not to have the wood slip or pull away from your hands. Once the blade is all the way through (the blade needs to be quite high), clamp the insert down. You will be cutting on the insert, which does not allow the bottom layer of plywood to chip downward because of the low clearance between the blade and the insert. The insert is sacrificial and it's usually only sensible to make one when cutting large amounts of plywood. To make safe cuts, make sure that whatever you're cutting isn't at an angle or unsupported on the other side.

How to cut plywood smooth?

1. Choose the right kind of blade. To get a smooth cut on a sheet of plywood, you'll need to have the right blade. Look for a carbide-tipped blade with a high tooth count. You can find blades labeled for plywood or "finished cuts," but make sure to check the tooth count.

How to cut plywood with zero clearance?

Alternatively use a zero-clearance insert under the plywood. To make one of these, carefully set a piece of wood or plywood onto the working table saw, taking care not to have the wood slip or pull from your hands. Once the blade is all the way through (the blade needs to be quite high), clamp the insert down. You will be cutting on the insert, which does not allow the bottom layer of plywood to chip downward because of the low clearance between the blade and the insert. The insert is sacrificial and it's usually only sensible to make one when cutting large amounts of plywood.

How to cut plywood with a circular saw?

Cut with the good side down. When using a circular saw, place your plywood on the cutting surface with the good face down. The teeth of the blade enter the sheet from underneath, and exit at the top. When the teeth exit, they may cause some chipping. Placing the sheet with the good face down will ensure a smooth surface.

How to get smooth cut on a table saw?

Choose the right blade. To get the smoothest cut from your table saw, invest in a blade with a high tooth count, such as an 80 TPI plywood blade.

How to cut a plunge saw?

Position your saw for a plunge cut. Place the front edge of the shoe, or the base plate of the saw, against your sheet of plywood. Carefully lift up the blade guard, and line the blade up with your cut mark.

How deep should a knife blade be?

Set the blade depth. Lower the blade to about .25 inches (0.6 cm) more than the thickness of your sheet. This will ensure the teeth of the blades just barely cut through the underside of the surface.

How to bend plywood around mold?

Use clamps to bend the plywood around your mold. Use bar clamps for plywood thicker than 1/2 inch and use strap clamps for thinner plywood. Strap clamps won't form depressions in the wood, but they aren't strong enough to bend thick plywood.

How long does it take for plywood to bend?

If possible, apply the rags on both sides of the sheet. It could take several days for the plywood to become soft enough to bend. During this time, be sure to re-soak the towels with warm water to keep them -- and the plywood -- wet.

What type of plywood is best for bending?

The best plywood for bending has a close-grained surface that won't splinter and separate when you bend it. For example, construction-grade fir plywood is not the best choice for bending, because the softwood fibers tend to separate under pressure, especially around knots. On the other hand, plywood with a close-grained hardwood face is less likely to splinter. Birch, mahogany and poplar are great choices.

What is the mold to clamp plywood?

Creating a mold to which to clamp the plywood is an important part of the bending process. This needs to be made from a rigid material that won't lose its shape when you clamp the plywood to it. The mold doesn't have to be elaborate -- a metal bar may do the job -- but keep in mind that it will determine the accuracy of the bend.

How many feet can you bend 1/4 inch plywood?

You can get a bend radius of as little as two feet by bending 1/4-inch plywood, whereas the minimum bend radius for 3/4-inch plywood is 12 feet. These radii increase if you bend the sheet along the grain of the wood instead of across it, because splinters are more likely to form when bending along the grain. Advertisement.

How long does it take to mold plywood?

Slowly tighten the clamps to force the plywood into the shape dictated by the mold. You may be able to do this over a matter of hours for thinner plywood, but for thick plywood, expect the process to take days.

What to do if wood has separated from surface?

If any of the wood has separated from the surface, you may need to cut it off with a knife and fill the resulting depression with wood filler. Tip. Look for plywood made with water-resistant glue. If the glue isn't water resistant, the layers may separate when you soak the plywood. Advertisement.
