Topic tags/keywords: question

i was watching Jory Brigham’s method in making bed in this video:

and wondering about the gluing lumbers over plywood.
i think because of different expansion rate of solid wood and plywood this bed will fail (some cracks, glue failure, etc.)
what do you think?

Yeah, ultimately that will fail.

You are correct, IMHO. A lot of time, effort and creativity into something that isn’t going to last.

Looks cool, but it will crack over time and that may not matter to them.

I made a bed from the video of Charles Neil (pencil post bed) and I laminated multiple layers to form a solid rail.

The rails were laminated together to give strength and prevent twisting. It worked well and has for many years now.

If the laminations was solid wood over solid wood and no cross grain condition existed, it would work. I feel that will crack over time.

Looks pretty though.

I learned that lesson the hard way. Warps, cracks and nightmares.

He needed to use Elmer’s school glue, to keep this from failing.

Haha, OR Jory knows something we don’t about plywood + hardwood. Maybe the wood he used is super stable, possibly even fake poly wood. Ya never know! I’ll just chalk it up to TV Magic.
