What is plywood made of?
Plywood is made from thin layers of wood shaved from logs. The layers, called veneers, are orientated so that the grain of one layer opposes the grain of the layers above and below. The opposing grain directions make plywood a stable product that resists warping and expands and contracts evenly with temperature and humidity changes.
Where did plywood originate?
By Michael Logan. Plywood is a laminated wood product with origins that date back to ancient Egypt and China . In 1865, the first patent for plywood was issued to John K. Mayo.

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.
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.
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 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“.
