Default Is it the most expensive plywood ever?

Pound-for-pound it might be. It's Finnish birch aircraft plywood - the 1/64" (0.4mm) thick stuff. I can't post a link until I get 'older', but it's at the Wood products > Plywood page at the Aircraft Canada Spruce website. I'm thinking about ordering some and then try to come up with a project to use it.

Has anyone ever worked with plywood this thick?! Is Finnish birch an actual species? And are there any sources for very thin veneers (single thickness)? At the nearby dollar store they have some purses made of very thin wood - made in China - for a buck.

So many questions. So much wood. So little time....

Thanks!

To reach your 10 posts just go to the introductions forum & say hi to a few new people. It just takes a couple of minutes. especially since you need just one more.

Aircraft grade wood is always expensive. Weight to strength ratio is key. I have a gang of friends that meet every Wensday night as they are all building Legal Eagles (experimental class plane), based on one a friend built.
(wood is used in the wings of this craft)
Unless your building an aircraft, I would shy away from such expensive lumber.

Can that thickness measurement be right ?
It says it's 3 ply and yet less than half a millimetre thick ?

I build acoustic guitar bodies from 0.8mm ply. I always thought that aero ply had an even no. of plys 8 or 10.

Yes, that's what it says on the website. It's 0.4mm 3-ply plywood.

Guitars?! Cool! I'd like to build a guitar too, one of these days. I'm retired and have decided to get back into woodworking.

That's an unusual guitar you're working on. Are the specs online somewhere?

Thanks......

How many ply is that Mike ?
Here, the thinnest veneer available is 0.6 mm . I can't imagine how they can make ply thinner than that.

Let's see.. that 48"x48"x0.4mm (0.016") sheet of ply sells for what, $53.75?

That sheet of plywood is 36 cubic inches... at 144 cubic inches per board foot... that's 4 sheets per board foot... Oh my!

Check out that new high-tech cordless router.. wireless and no recharging required!!

On the travel guitars, I generally use 2 layers of 0.8mm ply for the sides, joining at the neck block for a bolt on neck, with a shaped and glued in tail block to take a strap pin or strapjack. A variety of shapes are achievable by using shaped blocks as mandolins use. The ply forms its own curves without any heated bending.
