got a hardware display that used some really stiff ply



think it has 7 plys iirc



is this what is called baltic birch ply



was surprised how stiff this stuff is



if not baltic birch what is it


The 'baltic birch' was a Soviet-era collaboration between forest harvests in Latvia and high-quality plywood manufacture across the border in Russia. Panel sizes were metric ("5 feet" square, but really 1.5M square...) With the Baltic states joining NATO, there was a brief hiatus when that product was unavailable...

ApplePly is a domestic equivalent , and mostly available through normal distribution channels. And in 4x8 size.

just found a russian birch out of finland and or russia

might be what i have

i see there is even one has maple face veneer

Is it hardwood ? if so Baltic.

If it is marine glue and spruce or something - might be marine ply.

I have 3/8" steel that weighs like 1/2" steel due to content.

I have 1" ply that is normal pine ply. Just thick. Two 24" squares. :-)

So in wood, the content of the material (wood) is important and the type of glue is important.

I'd second the "baltic ply" - much of it from Finland and available in

4X sheets. It is my building material of choice for cabinetry or anywhere strength and stability are required. - like jigs.

My supplier offers BB in 60x60 and something similar in 4x8 sheets. The

4x8 sheets tend to be much more expensive per square foot.

1/2" 60x60 $19.95 1/2" 48x96 $32.95. About 25% more expensive per square foot.

I build 99% of my drawers sides out of 1/2" BB.

Baloney. If it's birch, then it might be Baltic birch. If it's some other hardwood, then it's whatever kind of hardwood that is (cherry plywood or maple plywood or whatever - bearing in mind that the inner plys will be poplar).

Also baloney. Spruce marine ply is all but non-existant today. If it's marine ply it'll be one of the mahoganies. (noting that you can find softwood ply marked "marine", but it won't pass BS1088 or other marine plywood standards).

There ARE "solid hardwood" plywoods with other than birch top plies from specialty plywood companies - some of which ARE Baltic Birch. Langevin Forest products supplies Baltic Birch with Cherry, Red Oak, Maple, and Black Walnut top plies in 4X8 sheets.Sometimes sold as "European Cabinet" stock. There is other 17 ply product out there that looks like baltic ply but has "s***ty" center plies - called China Ply.

not certain but i think not looks like the stuff in the earlier link

thought it might be marine ply but i looked at some marine ply and it looked nothing like that

put it to good use for a steady jig and it is steady
