Radius Bending ply

Has anybody tried this stuff?

Comes in an 8'x4' cross grain - which would be good for trailers wider than 60".

I used it on the tight radii of my first build. It's pretty soft and has a quite open grain, so I'd recommend covering it with something fairly solid. I epoxied it without glass before painting and had to use a lot of epoxy to get a smooth surface.
Use some straps to keep it on while securing it. I didn't at first and a few staples pulled right through it.

I have found this to be true when going length wise. But I'm looking at a 66" - 69" wide trailer which is going to require bending width wise, and I haven't been able to find any normal ply with a cross grain cut (local anyways).

I've used it for hundreds of reception and library stations, like pictured in your link, with veneer or plam coverings.
It will break quite easily by bending & squeezing it in your hand. :thumbdown:

I sill have a few sheets left over and I'd never use it for anything other than it's intended use, in a interior application.
Go with something like Baltic/Russian Birch plywood.
It bends great and so far the piece of 1/2" I have in a bag filled with water (since September 18TH, 2012) is still laminated as tight as day one.
:D Danny

Thx guys

Looks like I will be looking for some sacrificial ply to practice cutting kerfs.

Larry...I see you're in Rancho....did you try Hughes Hardwoods? They have bendy ply...saw it 2 weeks ago. I wouldn't use it however...it's a bit too bendy/soft in my opinion. For me, on a hard bend, I do 2 layers of 1/8" if it's going to be exposed and no aluminum. Doug
