I just picked up a bunch of plywood for free, is it possible to do anything with it? I'd like to have a desk, but I don't know if wood this thin would do the job.

How thick is it? Is it pressure treated (PT)?

does it have any markings on it?

Yes

Also it's a bit less than 1/2 inch

I could tell you a good project if you have 5/8" or 3/4" cabinetry-grade maple plywood, but What can you use 1/2" for unless you want to make a cheap bar-top arcade cabinet.

1/2 inch will make better book shelves than you can buy from ikea.... you can always double it up into 1 inch...

... You realize you can glue 2 half inch sheets together (remember outside plys always face the same way to keep it from warping) and have 1 inch plywood? just glue, place, and weight down. Either use a paintbrush or make sure to swirl the pieces a few times to spread the glue well.

>> No.801220

Yes create diaphragms, do this by buying 1x2 wood or 1/2x1 sticks. glue them to the edge creating framed piece cut to shape. thenin the field place them no more than 6 inches apart, gluing all this together and stapling them cover with veneer. for the desk top buy one piece of 3/4 plywood and make that the top of the diaphragm for the desk top. sand to a fine finish and then lacquer finish, or bartop.

In that case glue two panels tegether. It would be enormously strong and suitable for furniture projects.

Pressure treated lumber will often have a greenish tint to it.

Look for KD (kiln dried) and HT (heat treated) stamps. Avoid ones that have MB (methyl bromide) and pressure treated lumber, a caution you already have, because it contains some nasty copper compounds and arsenic.

Any n00b guides to building furniture? I'd like to build a small nightstand. Also is it possible to make legs with plywood?

yes you can make legs with plywood, but you have to keep in mind the limitations of the material and design accordingly...

make sure your legs are at least L-shaped or something, because plywood warps some.

also pick yourself up some wood glue
most wood glues are stronger than the wood itself

come to think of it, just dip the whole desk in wood glue

>> No.801269

there are like 400 different kinds of plywood. Post a pic, or pretty much anything we say is bullshit. I can think of all kinds of great shit you can do with certain types of plywood.

make speakers by stacking layers of plywood, makes an awesome speaker.

If that's it in the picture, then it's not plywood. That's veneered MDF by the look of it.

I went to the Toronto Archives and happened on a box full of building pamphlets and magazines. I was more interested in brickwork, but I took pics of some plywood ones.

Here are the plywood ones:

If its thin you could always laminate two pieces together, a fuck load of glue and a fuck load of even pressure over the surface and as many clamps as you can.

Haha. That's funny, because nowhere did I say that I came into possession of something for free.

What I did say, however, was that I went to the City of Toronto Archives (translator's note: an archive is a place with many old things in many boxes). While scrolling through their online catalog fairly aimlessly, I happened to find a box of interest in brickwork, so I summoned the box. In said box, there was also a file containing pamphlets and magazines on wood trim and plywood from the 20's to the 50's.

This wasn't Rob Ford's back alleyway, son. I was wearing white cotton gloves for this.

One cool thing i have done is make plywood picture "frames"

Take a picture

Cut the plywood 1" bigger on all sides.
( in your case double up the plywood and also make it 1"thick)

Usr a round over bit and route the edges.

Place the picture on the plywood. Held in place with a glue stick.

Apply painters tape around the out side edge , sticking up an 1/8 of an inch.

Apply bartop resin. The tape will act as a dam.

Let it cure. Remove tape. Done.

Did a bunch for a friends coffee shop.
