Why is Baltic Birch 5X5 instead of 4X8?

[Earl McLain]

I hadn't looked in a while--place near me is now at $81 for 5 x 5 18mm ($78 for 4-9 sheets). I'm thinking that 18 months or so it was in the $150 range, but that is a fuzzy memory. Seems reasonably close to pre-pandemic and pre-war.

This thread begs the question of why 4 x 8? When and how did building in the US standardize on doing things in 2 ft increments with 16 or 24" spacing? There's no indication in older houses that the spacing was anything other than whatever looked good to the carpenter involved, and plenty where there is no particular consistency within a single structure.

1.5 M square seems as sensible as any other measurement for cabinet plywood-- does it fit 32 mm cabinet dimensions particularly well? Construction in most of Europe uses vanishingly little sheet goods and US standard construction methods with stud walls is regarded as a very inferior method suitable only for temporary structures and cheap commercial space, if that. (Masonry and framing timbers being the norm)

because they fit in the wallywagon.

Trees in the taiga are stunted and short. Much easier to get peeler logs 5 feet long then 8 feet. Especially if you are trying to get knot free wood.

I believe the Finn's equipment was 5x5 when they where teaching the Russians how to make plywood is why they made 5x5 (btw they also make 4x8 too)

My local supplier carries both 4x8 and 5x5 Baltic birch in most thicknesses. Pretty sure I remember seeing the edge of the 4x8 stuff stamped with Russia, just like most 5x5 sheets, but could be wrong. I know some Baltic products are manufactured in Finland, and I assume across the entire “Baltic” region. Like Larry I usually prefer/buy 5x5 sheets. The 4x8 they stock around here are annoyingly a true 48”x96” as opposed to being slightly oversized for squaring up

John, look for Columbia. I use it in prefinished maple and it is 96.5 x 48.5 and pretty consistent.

[Larry Edgerton]

The Baltic birch I got was from Russia, which might explain the supply issue. It's metric. The supplier would have 4x8 sheets,as well as the 1.5m x 1.5m, but still in metric thickness . I got one of his last 12mm 4x8 sheets recently. Dado stacks aren't a problem, but router bits require a trip to the tool store.

I take my old 3/4 bits in to a sharpening shop and they grind them to fit metric. I know you can buy metric, but this is almost free and I can have them in small increments to fit whatever.

[Larry Edgerton]

Full lift pricing for 4x8 3/4" BB/BB is currently $98. 10+ is $107 Just before Covid I was paying $57 full lift and $65 full lift for Columbia 3/4 prefinished maple 2 sides. I have not bought any since as I bought several lifts just before Covid, but it says "Call for price" which always makes me flinch. I am almost out, so I will know soon.

Larry, yes I also get Columbia pure bond prefinished maple a lot for cabinet interiors. I guess I was just trying to say that the 4x8 Baltic birch throws me for a loop being undersized compared to the Columbia products you point out.

Ah, got ya. I hate finishing or I would use baltic for everything.

Larry, I completely agree. I would too, as I feel baltic is superior in every way except that I have to finish it! I too hate finishing…

When I bought a bunch of baltic birch ~4 years ago, it was in 4x8 sheets and from Russia (Cyrillic writing on it)

More recently I've bought some, also in 4x8 sheets (different supplier), but it is coming from Vietnam or other place in SE Asia. Sort of blurs the meaning of 'Baltic'. But the material looks otherwise identical to the Russian material (same surface, no voids, etc). Price seems reasonable now - at one point, BB was selling for ~3x the price of the stuff I bought 4 years ago - now it might be more like 1.5x the price.

I do wonder if location has any impact on the source of the BB - I'm on the west coast, so importing from Asia vs Europe may make sense via shipping, but opposite might be true for east coast.

It's probably still coming from Russia, but routed through Vietnam and relabeled there for export. I'm not sure that it's totally legal, but it's a pretty common practice in lots of stuff these days, in order to avoid tariffs or other restrictions. Basically, everyone puts a little money in their pocket to look the other way and business still gets done.

I mean, there aren't many, if any, birch trees growing in Vietnam. It's too warm there. Certainly not enough to support the export of it.

think I was told past the materials were sent to china and then made there. They have been buying our logs for 40 years and slicing thinner venner than we can.

This is a common thing, told Hardwood floors past made in quebec then rough material sent to china and made there and shipped back. They told me it was cheaper than here which is hard to fathom considering all the travel and back and forth. I was told by a supplier once there were even some shops on boats. I remember that as he said junk was dumped in the ocean. Maybe that stopped.

Nothing new how many tools past made in the US are made off shore.

Pretty sure I was told past the baltic birch was inconsistent as it was not always made in the same place even if the materials came from baltic states Latvia Estonia and Russia. Was told The trees grow harder and denser there from the cold. I can accept that as the red oak I bought from Michigan was different than the red oak from Pennsyvannia. At one point buying from both places and machining at the same time.

I know that offshoring of the production is what has resulted in a lot of lumbermills on the west coast shutting down. Instead of the material being milled here and then shipped out, raw logs were being shipped out and processed in Asia.

It used to be (and probably still is) that shipping stuff from US to Asia was fairly cheap, because the ships (and containers) had to return to Asia anyways to pick up whatever the US was importing, so there was excess capacity in that direction. So it just becomes an analysis of does the lower production cost offset more than the shipping cost, and in most cases, the answer seems to be yes.
