Is it going to be possible to make a kerfed box out of Birch Ply?

No one knows if this is doable with ply?

I can not image it being possible. Never tried it myself and never intend on trying it.

it may be possible but i dont see any big curves being done safely

you can always form it
just make a form to use and soak the birch and slowly bend it to shape

Should be easier actually as kerfing wasn't never really intended for MDF. Just cut through to the last 2 plys and you should be fine...

Look up "kerfing" on yahoo and all of the examples will be with some type of plywood usually or hardwood and they wet it when bending it...

Make sure to soak the wood in your pool

there should be no issues with getting BB wet, but I would try it on a test piece first just to be sure...

Actually steam would be a better technique then just water.
You can probably use a carpet steamer or hang it in the shower.

i remember seeing someone had a kerfed enclosure built with the baffle/port kerfed out of birch. the baffle/port was also stained which looked really nice and everything else was carpetted. you could always try with some scrap would.

You dont want to use regular Birch Plywood. Baltic Birch is the material you need to use. And yes, BB can be kerfed as far as I know. I have never tried it myself, but I have seen it done. Shouldnt be any different than doing it with MDF.

kinda ot but at work we have these thin (1/8"X3'X3') sheets of various kinds of wood, i was thinking of making a "jig" by routing my horn shape. a top and bottom groove, bending, gluing, overlaping them to whatever thickness i desire, along the way pieces of this wood. then just having to square the ends w/ the saw at the end. thoughts on this???

Thanks for all the help guys! If I could find Baltic Birch BJ I would be greatful, but nothing around here but ply. It's worked fine in the past, but with the bends, I could see it possibly splitting between the tiny spaces of each layer.

Although if you use the steam/water method, I could see it maybe working. I wonder if the integrity would be compromised in the strength of it after it is bent...

Steam bending works best with hardwood that was NOT kiln dried.

KILN dried? I assume you meant that verbatim. I could just dry it with a heat gun right?

Wait......do you mean kiln dried before it hit the shelf at the store?

I have kerfed regular fur plywood,birch ply,baltic birch and even hardwoods
but the hardwoods is a pain in the ***..takes alot of time and patience

Yep, just a random fyi about steam bending...

I wouldnt not recommend using regular Birch ply for a enclosure. It is not very dense, and have many voids in the core. Regular birch ply is no different than oak, maple, cherry, etc other than the veneer that is put on it. The cores are the same.

It looks a lot like yellow birch (much darker grain than baltic birch)

Might have to contact him about details.

I'm going to go ahead and have (yes, have...unfortunately, but I have no problem letting another forum member help me, help him) the box built out of Birch Ply. I don't care what anyone says. I have used Birch Ply on the last 7 boxes I've built and they all sounded great; everything from my XXX to the Realms to my SEs.

Yes, its a box by Belunt. He did some nice work. Too bad he decided to follow in Potts' footsteps...
