@Stumpy Nubs  Nope. Besides, I don't think the majority of Baltic Birch *ever* came from the Baltic States. They just don't have enough forest. And you said you should look for high letters and high numbers. I think you meant low for both. Please forgive the pedantry. :)

Really good vid! What' is and what distinguishes AC plywood, CDX plywood? Is "cabinet grade" a synonym for either? Is "Birch" the same as "Baltic Birch" and how is "Birch Veneer" different? The previous examples are from but two of Norm Abrams, NYW, material lists. TIA.

You just re-enforced everything I learned about plywood over a 35 year professional woodworking career. In a few words...what you call it don’t mean it’s what you get. I will, however, dispute one impression that you’ve left with us. Many plies do not necessarily make a sheet of plywood more stable. The retailers and cabinet specialty businesses are selling imported plywood from Asia that has MANY layers in its core...too many to count. I can promise you that it’s not even a little bit stable. Not only that, but I’ve seen the shipping wrapped bundles that state that formaldehyde, a known carcinogen, is used in the manufacturing process. Not noted on the individual sheets. Some may not think that matters but it was always a consideration for me. I never wanted to be guilty of introducing such a product into a clients home, or breath the off-vented fumes myself. It’s a serious enough consideration that the US and Canadian governments banned the use of formaldehyde in the manufacturing process of any construction material years ago.

At 3:02 "So when you buy plywood look for high letters and high numbers ..." When I learned the alphabet there was (and still is) an order to the letters but not a relative higher or lower value. In fact they were all high, on the wall above the chalk board. When I learned mathematics the number 1 is lower than 2, etc. Once I got into computing I learned that a numerical value was assigned to each letter of the alphabet in an ascending (low to high) order, value for A was lower than the value for B, etc. However, letter grades as assigned in schools for a student's work has the A grade higher in value than the B grade corresponding to higher number scores for higher quality work. Where is 1 considered higher than 2? In competition, first place, second place, etc. First place is higher than second place, so here 1 is higher than 2. Back to plywood: If you have a computing, engineering, math, science background then you should say lower letters and lower numbers are better grades of plywood. If you have a teacher or student orientation then you should say higher letters and lower numbers are better grades of plywood. If you are competition person then you should say higher letters and higher numbers are better grades of plywood. Which ever way you say it, it will be confusing to someone. May I conclude you are a sports fan? I am a computing, math, science fan and was a computer technology teacher for 35+ years which must be why your wording caught my attention. Thanks for the interesting video.

Very timely information. I feel like this segment of the market gets more confusing every day with the impacts the pandemic is having on the supply chain. In my cabinetry work, I continue to learn new things all the time and this was excellent. One note, you said the higher the number and letter the better the plywood but the engineer in me cringed since the lower number/letter is the higher grade ... unless I am missing something. (Apologies if this is somewhere in the abundance of the comments on this video). Thanks again for the insights. Great job!

The big plus for MDF is that when finished it looks smooth, no ripples like what you would see with plywood. The big minus of MDF is the weight. I used to have a helper who called the cabinets we installed Stone Henge construction. Additionally, you can use MDF for some “furniture” as long as you keep the center of gravity low so nobody gets crushed if it happens to tip over. By furniture I’m referring to table tops, hide a tv stuff and free standing cabinetry. No chairs, stools or the like.

Way back when I started in woodworking lumber core plywood was available. It had a thick core made up from a mahogany like hardwood (probably Luan) that took up over 60% of the thickness dimension. Lumber core plywood was expensive and was usually reserved for high end projects. Also Baltic Birch plywood often does warp over the 5 foot dimension so the extra layers do not guarantee that it will remain flat. By my recollection the veneer grading system for plywood was A, B, C, D and X for both sides so that a typical cabinet grade plywood might be AB or even AC and construction plywood might be referred to as CDX with "X" referring to exterior glue used in the veneer layers. But I haven't purchased plywood lately so maybe things have changed.

@Stumpy Nubs Sorry, wasn't being funny - just stated that it sounds odd to UK ears. As it happens we are used to both 3/4" and 18mm ply and floorboards as we used to use 3/4" and sometimes have to shim new when replacing. Interestingly, even though the ply is sold in metric thicknesses, the sheet is still basically 8' x 4' (2440mm x 1220mm) Similarly we sometimes have to use adaptors to connect to old imperial pipework and electrical conduit.

You are used to 18mm, so 3/4 is oversized to you. We are used to 3/4 so 18mm is undersized to us. See how that works?

Many years ago early/mid 80’s I took some Altec 2 way PA speakers. I made a separate box for the 15” woofer and separate box’s for the horns. The plywood I bought for it and I’m unsure of the exact name. But it was solid boards inside. 2” to 4” wide. Some times smaller occasionally wider. And it came with a pretty thick veneer outside. Not super think but thinker than any cabinet grade I’ve seen. I didn’t get at a big box store. It was a plywood factory/wholesaler. They sold much more than they made. And did custom woods and sizes. That was in Dallas Fort Worth. I’ve not found a factory here in Baton Rouge. But we have a couple of nice wholesale places with some exotic flavors. Speakers came out great. Wish I still had them.
