Hello,

Has anyone ever tried to make some at home ? From what I read on the
internet, industrially made boards are glued toghether by spraying resin
over the wood particles , then the result is pressed, and baked with hot
air.

I am thinking in giving it a try, with a home made manual press (not much
pressure) and possibly dilluting wood glue with tap water. Don't want to
baked it though. I'll just let it dry at ambient temperature.

I would use the boards for covering wood structures of furniture, so the
cohesion of the particles doesn't need to be high.

Regards

Wouldn't be worth the time, effort, and materials, as far as I'm
concerned. Even if I only considered my time worth 25 cents an hour,
still wouldn't be worth it to me. I can get a 4'X8' of OSB for just
under $6, including tax, plus the cost of gas to get it. I'd buy enough
other stuff to make the cost of the gas worthwhile.

You want a cheap press? Lay it out, put a thich sheet of steel on
it, and park a truck on the steel for a day or two.

I'd have to classify this under "cool thought, not particle"..
I see a few problems, besides not being cost effective:

What size boards and how big a press?

Can the pressure be even enough to get uniform thickness, or do you kill planer
blades running sawdust and glue through?

Covering wood structures of furniture?
Are we talking tarping or veneer? Neither application works for me, with home
made or manufactured particle board..

OTOH, if you could make it out of cherry sawdust you might have some cool
material.. ;-]

Having worked in the lab 40 odd years ago in the production of particle
board and the development of MDF prior to the granting of patent, I think I
can answer this. In the mix with the spray and the milling process to get
the lumps out and in laying the mold, some of the particles become charged.
In the pressing, electrical charges cause these charged particles to weave
into the others, not easily done at home. We made test boards then using a
2 ton press, high voltage variable amps; a 3/4 inch board began as 3 pieces
each about 8 inches tall.

Never mind. I am a hobbyist. My goal is to recycle wood that is left over
from other works.

Never mind that either, I have built one that is enough for my needs.

I don't know the numbers, but I'd say there's not a lot of us here
that woodwork for their main income - we're hobbyists in other words.
You recycle leftover wood by using it in another project, making small
things, appropriate to the size of the piece of wood - kid toys, jewelry
boxes, jigs, etc. Sawdust use as mulch, pet bedding (depending on wood
type, and animal type), traction in the winter, even make sawdust clay.
Wood too small to realistically use, can go in a bonfire, smoke meat,
BBQing; even make charcoal, then charcoal briquets. You can spend time
on making your own particle board if you want, but I'd consider it a
totally useless waste of time and effort. Better to think of some
activity that would be a useful waste of time. Your time, but homemade
particle board just seems so pointless.
