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.

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
